Searching high and low to find the best RV water filter can be frustrating. No one would want their RV’s water to be contaminated in any way. Simply put, it’s an important part of the RV experience.


In most cases, replacing the water filter in our RV is not something we look forward to, especially when it takes too long and too often. Nonetheless, the task is absolutely vital, but it doesn’t have to be time-consuming.

On your next road trip, ensure that you and your family are well hydrated and healthy by investing in a quality water filter.

An RV’s equipment might fail for a variety of reasons, which can be a huge problem. There are a number of reasons why it’s important to get it properly the first time around, and that’s what this guide is all about. We looked at dozens of products before settling on our top ten.

Our Top RV Water Filters Picks

1. Camco 4063 EVO Premium RV Water Filter – Overall Winner

Equipped with a 5-micron barrier that eliminates odors, germs, chlorine, and sediment from the water. The Camco also complies with all low-lead regulations, guaranteeing that you have a safe drinking experience.

No problem with adaptability either. Most hoses, as well as your RV’s, can be easily attached. After that, you can use it to clean your car or to take care of your garden. Calcium deposits and excess chlorine are effectively removed by the filter.

An installation tool and Teflon tape, as well as a filter housing, are supplied in the box. Because of this, it can technically last for a whole camping season, but how often you use it will determine whether or not it will actually survive that long.

Even though this is a subjective issue, some consumers have complained that the filter leaves behind a strong chlorine flavor.


  • Barrier with a 5-micron thickness that is designed to last a number of seasons


  • In certain cases, the chlorine taste may linger on your tongue for a while.

2. Waterdrop WD-RVS-1 RV Inline Water Filter – Best Buy

The Waterdrop is our most economical water filter. A great alternative if you’re on a budget. In order to optimize efficacy, the unit comes with a multi-stage filtration and has a three-month lifetime (about one camping season).

When it comes to drinking water, use Kinetic Degradation Fluxion (KDF). In addition, GAC (Advanced Granular Activated Carbon) reduces typical contaminants like chlorine, arsenic, or fluoride by filtering out bigger silt particles. An anti-crimping and anti-snagging hose are included in the package.

Despite this, buyers should be aware of the fact that many consumers claim that the filter significantly decreases water pressure, leading to a “poor flow” experience while using it. If your RV has low water pressure, this might be an issue.


  • Technologically advanced methods of cleaning
  • The hose that does not snag while at a reasonable price


  • It might lead to a decrease in water pressure.

3. Clearsource Premium RV Water Filter System — High-End Option

As one of the most durable products on this list, the Clearsource Premium RV Water Filter System provides its customers with a high level of performance. You’d be unlikely to find a buyer who didn’t like it.

Our top pick, Clearsource, will fit you wondering if you have a little additional cash to spend. Included in the set are two filters mounted on a robust steel stand. If your RV has a water source, the stand will use a three-stage purification mechanism to ensure maximum results.

I’m also thrilled by its 5-micron sediment filter, which performs a great job of eliminating sediments from the water. One of the second-stage carbon filters is capable of filtering out contaminants as small as 0.5 microns, including cysts, volatile organic compounds (VOC), giardia parasites, and chlorine.

A five-micron-sized particle is removed in the first stage of the filter, while contaminants and poisonous substances like chlorine are removed in the second stage. The third and last step focuses on taste. The  Coconut shell carbon block is used to enhance the flavor. They can treat around 2000 gallons of water with the filters they come with.

Thanks to its sturdy and solid construction, this premium water filter can also withstand much abuse. The stainless steel fittings and hardware are also a big plus. Thanks to the built-in stand, it’s also a breeze to use!

Of course, the cost is a major concern with its features. As a result, the price of the water filter is significantly higher.


  • Durable Powder Coated Chassis Increases the filter’s corrosion resistance.
  • Stainless steel fittings are more robust than ordinary fittings and less likely to leak.
  • A 5-micron filter in the first stage and a 0.5-micron filter in the second.

  • Filters with the most costly price tags on our list 
  • Filters with the most costly price tags on our list 
  • The hoses must be twisted because of the fixed hose fittings.

4. External Culligan RVF-10 Water Filter

An external water filter, the Culligan, is a low-cost option for those who want to save money. With a robust filter shell and brass components, it is meant to last outdoors. For better water taste and odor removal, activated carbon granules are utilized.

Every feature of this water filter has been created to fulfill the needs of every RV owner who is looking for a new model of this type of water filter in particular.

For example, this product’s design is exceptionally durable and long-lasting. Well-made filters are difficult to damage on your travels. Due to its robust design, the drinking water is also more flavorful and refreshing.

In addition to being durable, this design ensures that the storage tank will be cleaner, minimizing the amount of maintenance you have to do in order to keep it clean. When you’re a person who hates cleaning, this feature is a godsend!

A deeper study of the unit reveals that it is only licensed to clean 250 gallons, which may not last as long as it claims. Users claim significant leakage as well as a possible reduction in life expectancy.

Easy installation is another feature that indicates how convenient this device may be for the lucky buyer. Installing this device will be easy thanks to its elegant appearance and included hose fitting kit.

It comes with an entire manual that leads you through the entire process. Furthermore, people loved the instructions, so I decided to include it. Also included is a filter cartridge, which has been proven to be quite successful at removing sediment and other things like bad odors/tastes from an RV’s drinking water supply.


  • Durable for the outdoors
  • The first level of filtering eliminates unpleasant tastes and odors from the water supply.
  • Does not allow unfiltered water to get into the RV’s tanks.
  • Perfect for the holiday season.

5. ESSENTIAL Premium RV Water Filter With Cyst Removal – Best Sediment Filter:

A heavy-duty sediment filter that will also be permanently installed inside your RV, such as the RV Water Filter Store’s Essential RV Water Filter System, is a great choice because it comes with the essential 12-inch mounting bracket to help you secure it within your RV. Heavy-duty NPT fittings on this filter make it more durable than a standard hose fitting.

Furthermore, these connectors are substantially more durable over time and are less likely to leak if they are slightly bent under the weight of your water line or the filter unit itself. This filter system also comes with an extra 1-micron filtration cartridge which personally makes me happy.

This filter should be changed every six months, so it should last you at least a year with all of the parts that arrive at your door when you order. While sediments are removed from the water, the filter also eliminates giardia and other contaminants.

Aside from improving the quality of water, it protects pipes from chemical and sediment buildup over time. An excellent flow rate of 3-4 gallons per minute (GPM) is achieved at 60 PSI (pounds per square inch). Because of this, it won’t interfere with the effectiveness of your dishwashing or make it harder for you to remove soap from your hair when you’re taking a shower.


  • The heavy-duty NPT fittings outperform standard hose fittings in terms of durability and reliability.
  • This filter comes with a spare 1-micron filter included in the box.

6. Camco TastePure RV Water Filter 40043

To anyone searching for a high-quality water filter made for RV use, I will always recommend the Camco 40043 TastePURE water filter. Initially, I was drawn to this filter by its great capacity. Apparently, it has a larger capacity and can last the whole season.

High flow rate capacity due to its large design and 20-micron sediment and carbon filter, which acts to dramatically minimize bacteria formation in the treated water.

This feature is particularly useful because it delivers clean drinking water, regardless of the source of water. Drinking water purifies chlorine and smells by eliminating sediment, odors, and tastes.

Aside from that, it’s perfect for use at any camping site. It also prevents mold, germs, and fungus from growing in the filter, even if it isn’t used.

Everyone says the threading is not up to par. You may have trouble connecting it to your RV if this is the case. Most customers don’t want to deal with the trouble of going via the manufacturer’s warranty if they run into this problem because of the hassle.


  • Small sediments up to 20 microns can be removed with this device.
  • It can be linked to garden hoses
  • Certified Lead-Free
  • Flexible hose

  • Grains of KDF that improves filter performance


  • A problem with the threading may exist.
  • It will only last for three months.
  • Comes with no case to keep it clean and safe.

7. AQUA CREST RV Inline Water Filter

AQUACREST RV KDF Water Filter is one of the more versatile options on our list. Because this product may be used in cooperation with the Camco water filter, it is quite practical for the consumer.

A good value, the Aqua Crest comes with two different filter cartridges. For a clean and delightful drinking experience, it has a 20-micron filtration rating with GAC, KDF, and fluoride removal. Your iron, fluoride, chloride, and other pollutants will be removed with ease.

Another good quality of the Aqua Crest is that it’s versatile. If you want to clean your car or water your plants, you can use this hose. To eliminate snags, the package contains an anti-kink hose connection point. The package should last for roughly three months.

After all that, though, it’s difficult to recommend the fixtures due to their quality. Threading connection points and flexible hose connection points are both inefficient. There are certainly better filters out there than this one, but this one isn’t so bad.


  • Reasonably priced
  • Comes with two cartridges.
  • The flexible hose that doesn’t tangle easily 


  • The threading connection is prone to being defective.
  • There is no reason to use the hose connector, as it is completely pointless.

8. Beech Lane BL-113 RV Dual Water Filtration System

There are a number of features in Beech Lane’s External RV Dual Water Filter System that will ensure that your RV is supplied with clean water. Such as its lead-free brass fixtures that will provide a secure connection and eliminate problems like hose leaks, which I find quite appealing.

For added durability, the Beech Lane comes with two cartridges. Using a dual micron filtration system rated at 5 and 0.5 microns, respectively, the device removes dirt, sand, and other larger particles as well as tiny particles, such as dangerous chemicals. In addition to improving the water’s flavor, it also enhances its smell.

The cartridges are also capable of treating up to 1,900 gallons of water, which is quite a bit in an RV. But some users of the equipment have complained of leaks. Even though this isn’t a common event, it’s nonetheless worth noting.

  • Several sources have indicated significant leakage.
  • Filtration of UV or reverse osmosis is not available.

9. Culligan RV-800 Outside Pre-Tank Water Filter

A good RV water filter to consider is the Culligan RV-800. Because of how effortless it is to connect to RVs, boats, motorhomes, campers and trailers, this water filter has surprised me.

Attaching the 12-inch flexible hose is a breeze because of its flexibility. Another feature that makes it ideal for recreational vehicles is its slim design. My confidence in its capacity to eliminate chlorine odor and taste, as well as germs and sediments in water, comes from its quick fill design and high flow rate.

As an added bonus, it has an impressively long cartridge life and can hold up to 2,200 gallons. Its compatibility with all standard hose fittings is another characteristic that makes this Culligan water filter for recreational vehicles special.

From 40 to 100 degrees Fahrenheit, it’s well suited for the task at hand

Some issues were found that you should know about before purchasing this product. Some customers may be put off by how cloudy the water produced by the system is. In addition, it lowers the water pressure in your RV’s water system.

10. Watts 520022 RV Duo Outside Water Filter

This water filter’s suitability for RV and boat users was the first item that stood out to us. For any RV owner looking for a water filter, the garden hose fittings come in very handy.

In addition to being well-suited for usage in RVs, its performance isn’t awful at all. In tests, this Watts RV water filter removed 99 percent of cryptosporidium, cysts, and chlorine from your water, as well as undesirable tastes and smells.

There are two filter cartridges included with the Watts, and the treatment capacity is 2.5 gallons per minute, which is water that should be enough to handle any faucet and the majority of showers. Cryptosporidium and giardia cysts, as well as sediment and chlorine, can be removed with 99.9% efficacy.

Sadly, the package’s best feature may be the housing itself, which is a shame. The rest of the bundle isn’t as durable as it is. Because the cartridges leak and the threaded connection points wear out quickly, the installation might be difficult if not impossible in some cases.


  • Effective use of two cartridges and a sufficient water flow


  • Faulty threading and leaking cartridges.

11. Waterdrop TSU 0.01μm Under Sink RV Water Filter – Best Under-Sink Filter

To filter water for just one or two sinks in your RV, the Waterdrop TSU 0.01-Micron Filter System is a great option.

In addition, it features one of the finest filter components of any model on our list, with a lifespan of up to two years. Your water is filtered to eliminate 99.99% of all sediments, bacteria and protozoa, and other contaminants with a 0.01-micron filter element.

As soon as the filter element has been fitted beneath your sink, it may be simply removed and replaced without having to remove the entire device. The Waterdrop is also equipped with Smart Technology, which provides information on water quality and operation mode.

  • Changing the filter is quite easy.
  • With a 2-year warranty on this filter, you can be certain that your investment is protected.
  • When a filter has to be replaced, it will notify you ahead of time.
  • Installation is made easier, and there is less leakage.


  • Considering that it does not filter ALL of the water that enters your RV, this filter is a little pricey for what you get.
  • These filters are not designed to safeguard your RV’s water lines because they are put under the sink.

12 Waterdrop G2 RO Tankless Osmosis Water Filter – Best Reverse Osmosis

Long-term users will benefit from this technique of filtering as there is no need to change the filter every few months.

Consider the Waterdrop G2 RO Water Filtration System if you’re looking for a RO water filter. With a flow rate of 0.28 gallons per minute and a tankless design that helps you save space, this filter’s high flow rate is a result of its style.

A composite filter, which has a long shelf life and is designed to be changed every six months or so, is also used in this system, as well. In spite of the heavy water consumption, the filter replacement rate stays consistent since this filtration system is designed for family RVing.

One of the filter’s components is an activated carbon block, while the other is a polypropylene (PP) membrane. Sludge, rust, and fluoride are all successfully removed by a combination of membranes with carbon blocks.

In your water, you should not find heavy metals, colloids, large particles, and other organic things. Tankless technology allows this filtration device to be 70 percent smaller than traditional under-the-sink water filters.

In order to fit neatly under your sink, Waterdrop designed this filtration system with integrated water and electricity connections. In addition to reducing leakage, this design reduces the possibility of power outages if water spills from other parts of your RV’s interior.

A 30-minute installation time is possible with the WaterDrop G2, provided that all instructions are followed precisely. As soon as the main body of the filtration system is fitted, the filters may be removed and replaced by simply twisting and pulling out. The whole process takes less than three seconds, and you’ll be back to filtering clean, pleasant drinking water in no time at all.


  • At the very least, the filters in this system are designed to last six months.
  • As a result of its design, you’ll save room under your sink while simultaneously improving the flow rate of this system.
  • Decreases leakage and increases safety by reducing power outages.
  • Installing replacement filters takes only a few seconds after the first installation.


  • There are cheaper RV water filters on the market, but due to reverse osmosis technology and space-saving design, this isn’t one of them.

13. Viqua S2Q-P/12VDC Silver Series – Best RV Ultraviolet (UV) Purification System

Designed with RV electrical system standards in mind, the Viqua S2Q-P is an RV-specific device. With this RV water filter, both you and your passengers will be protected from harmful bacteria found in untreated water sources.

The Viqua S2Q-P runs on 12 volts, but many UV purifying systems run on 120 volts or more, according to the manufacturer. There are usually three electrical systems in RVs, including one for the car (12-volt system), one for the RV (120-volt AC system), and one for the RV (12-volt DC system).

This system works only when the RV is hooked up to a 120-volt electrical source at the campsite, although it’s always on when it’s 12 volts DC. Most likely, if you’re going to be working with possibly polluted water, you won’t be near a campground.

Elegant, lightweight, and small, the unit fits nicely under your sink or under your storage tank in your RV. In addition to a green LED light that indicates that the device is operating properly, there is also a warning that sounds before you drink the potentially hazardous water.

Antibacterial and cyst-killing technologies that employ ultraviolet light remove bacteria and cysts from untreated water sources without requiring chemicals or the production of any waste.

It’s important to have a UV purification system in your RV if you often travel to remote areas where clean water is uncommon. With a UV system, you and the other passengers on the RV are kept safe and healthy.

For untreated sources such as rain or surface water, including such lakes and streams, the Viqua S2Q-P is also capable of filtering water (though if you are drawing water from a lake or stream, it is always judicious to have a water analysis performed first.)

As rust and sand particles may encapsulate germs and protect them from ultraviolet light, UV systems work best in conjunction with a sediment filter.

As part of the Viqua S2Q-P, a sediment filter kit is included that may be placed in front of the UV lamp to enhance overall system performance. It is advised that a carbon filter be put before the UV system, as UV light alone will not enhance the flavor of the water.


  • Eliminates 99.99% of harmful bacteria.  With a compact and thin design, it easily fits under the sink.
  • 12-volt DC system for RV compatibility
  • Durable results are provided by its high-performance light
  • Designed with off-grid uses in mind.
  • LED lights for additional functionality
  • Has an integrated alarm to indicate when a lamp malfunctions
  • Quick contact time and high flow rates


  • Water gets quite hot if kept in the chamber for a long time
  • Needs sediment pre-filters are required for optimal performance 

What exactly is an RV water filter?

In an RV, water filters remove silt and other pollutants from the pumped water. As well as reducing chlorine and eliminating sediment, RV water filters also prevent clogging, premature failure, and damage to your plumbing and appliances.

There are a variety of water filter options available to you if you have more specific water concerns when traveling. It is possible to make untreated water drinkable by using ultraviolet (UV) equipment. Remove lead from your drinking water by using filters that filter out heavy metals present in old, corroded pipes.

Water filtering is also a less expensive and ecologically friendly option than buying bottled water in an RV, which may be costly and environmentally damaging. Depending on the coach size, budget, and RV lifestyle, you can customize your RV water filtration system to meet your unique needs with ease. Whatever your situation, an RV water filter will make your trip more enjoyable.

What are the benefits of using an RV water filter?

  • Clean water: Make sure your trip isn’t ruined by unpleasant scents and filthy water. The quality of water you’ll encounter on the road is impossible to anticipate, so make the most of it by equipping your RV with a water filter before you hit the road! Taking a shower or drinking contaminated water will be a thing of the past. Investing in a basic RV water filter can give you peace of mind and enhance your entire experience.
  • Keeps your RV’s plumbing from becoming clogged: Your RV’s plumbing is less likely to become blocked with sediment. Blockages in pipes are caused by sediment accumulation. You’ll also need to do more regular cleanings, and your water quality will suffer. It is possible to prevent silt from entering your RV’s system by installing a simple inline or canister filter.
  • Flexible options: For RVers, there are many different alternatives for water filtration, regardless of the amount of filtration requested. From putting reverse osmosis membrane technology under the sink to just hooking up hydrants to get rid of that chlorine taste, there is a solution for your water quality issues. Examining your RV habits and studying available options might help you discover the perfect match.
  • Environmentally friendly alternative: There’s no need to worry about all that plastic ending up in the garbage if you’ve been using bottled water while on the road. Water filters are considerably more handy and cost-effective than lugging cartons of bottled water. Purchasing bottled water might be expensive. Filtering water also reduces the necessity for pre-purchasing it.

What is the function of an rv water filter?

In order to use an RV water filter, it must be installed in the RV’s present water system. A filter is used to ensure that only clean, filtered, and disinfected water are sent to your faucet once the water is drawn from your municipal water connection or water tank.

Furthermore, the best filters also eliminate tiny protozoa and bacteria, which may be harmful to your health if they are present in your water. One of two basic filtering methods is used to purify your water using these filters.

Some people employ physical filtration, while others use chemical filtration to purify their water. As mentioned above, the top models employ both of these filtration methods.

Filtration by physical means

If you want to get rid of large particles from water, physical filtration is your best bet. Dirt and other particles are collected when the water passes through a sieve-like device. Big particles may be removed with a fine textile membrane, whereas smaller particles can be removed with thin gauze.

Filtration by chemicals

Your water will be disinfected by chemical methods by utilizing a chemical that is known to eliminate bacteria and protozoa, as well as other contaminants that might cause disease.

Many chemicals are used in water filtration, including iodine, chlorine, and algicide. If you’re looking to remove possibly harmful microorganisms from your water, this type of filtration is the best.

Both of these filtering processes will be used by the best RV water filter, as we briefly mentioned above, to remove big sediments while also neutralizing small bacteria and protozoa.

RV Water Filtration Types

Use frequency, water pollutants, and desired water quality will all influence which RV filter system you pick. In order to make an informed decision about which system to purchase, you need to know what each filter choice offers.

Filters made of carbon

Using a carbon filter to remove chlorine and chloramines from your water will enhance the taste and smell of your water.

Carbon filters are one of the most prevalent methods of water filtration. By eliminating chlorine and chloramines from water, carbon filters are well-known for their ability to restore freshwater flavor.

Municipal water sources are disinfected using chlorine. To kill bacteria, chlorine penetrates their cell membranes through a process called oxidation.

Water that has been chlorinated, on the other hand, has an unpleasant chemical flavor and odor. Adsorption, a chemical process, effectively removes chlorine from water. During the water filtering process, contaminants adhere to the surface of the carbon block like Velcro, allowing them to be cleaned out.

When it comes to water, carbon has the ability to help clean it of pesticides, weed killers, and other VOCs (volatile organic compounds). As long as your water supply is free from harmful bacteria and heavy sediment, you can benefit from a carbon filter in your RV.

Filters for Sediment

In addition to removing particles from your water, sediment filters preserve your RV’s plumbing and increase the life of your other filters.

An RV sediment filter is essential when dealing with filthy or debris-filled water. If your water is polluted with sediments, it will have a murky brown or yellow color, as well as an unpleasant flavor.

Water and equipment in your RV can be damaged by sediment as well. A buildup of dirt and debris may block your RV’s plumbing, causing damage to your toilet, shower, and faucets.

As a result of sediment build-up, water pressure might be reduced, resulting in expensive, unnecessary repairs. Additionally, sediment reduces the efficacy of many water filtering devices. In the presence of high sediment, carbon rapidly uses up, while silt and particles prevent UV rays from effectively sanitizing your water and keeping it safe for human consumption.

Everyone who owns a recreational vehicle should use a sediment filter on their water supply. It’s necessary to use a sediment filter if your RV is hooked up to anything other than municipal water. You can extend the life of your RV and other filters by including sediment filtering into the design of your RV system.

Purification using Ultraviolet Light

For water that is microbiologically dangerous, UV systems are the perfect filtration method.

Viable microorganisms such as bacteria are rendered useless with ultraviolet purification (UV). These microorganisms have the potential to be pathogenic, infecting you and anybody else in your RV with waterborne diseases.

Pathogens are prevented from reproducing in water by using UV lamps to disrupt bacterial DNA. This prevents them from polluting your water and spreading disease. The use of a UV system is recommended if you are planning to travel to locations where the quality of the water is dubious.

In addition to sterilizing the water, UV does not improve taste; therefore, use it in conjunction with another RV water filter system to get the best results. Water that has been sitting idle in a storage tank can be treated using a UV purification system, as well as water from a well or untreated source that has been exposed to bacteria.

Reverse Osmosis

In order to obtain water that is free of virtually all dissolved solids and of high quality, one needs to use reverse osmosis technology (RO).

As one of the most extensive and powerful water filtration systems available, reverse osmosis (RO) stands out from the others. As the water is pushed to cross the membrane made up of small pores, the dissolved salts and debris are removed.

Filtering the water before it passes through the membrane by using a sediment prefilter and polishing it with a carbon postfilter improves its taste. R.O. is a highly effective method of purifying drinking water, but it isn’t practical for the majority of RVers.

However, despite the fact that RO systems are growing increasingly popular among RV owners, the amount of space they demand is problematic for most RVs.

As well as a huge number of wastewater booster pumps, reverse osmosis systems call for a separate storage tank. It’s called brine, its waste product, and it’s pumped out of the system into the drain, along with the contaminants it contains.

Around 80 percent of the water treated by RO units will become brine without a permeate pump to reduce waste. Due to the fact that most campsites do not have drain hookups, this could be a challenging procedure. If you have the time and space, a reverse osmosis system in your RV can provide you with high-quality drinking water.

Buyer’s guide

Many factors must be taken into account when choosing a water filter.  An equipment’s performance is influenced by many factors. This section can help you make a better-informed purchase decision by breaking out some of these elements.


The purpose of today’s tutorial is to demonstrate water filters for RVs, as the title suggests. In contrast, if you buy a product that can serve two purposes, you’ll get more for your money. The use of hose bib adapters allows for the use of several water filters outdoors.

Numerous benefits can be gained by using a water filter to purify the water from your garden hose.  Start by remembering that the same substances you’re trying to stay away from can be harmful to your plants. Using a good water filter may reduce calcium accumulation, which can be an issue when washing your car.

Your filter’s functionality will be enhanced if you invest in something versatile, which may prove to be pretty advantageous in the long run.

Water pressure

Sadly, RV water filters often result in a reduction in water flow. Though that is true in some cases, it is not always the case. Water production capacity is even stated on certain filters. “Gallons per minute” (GPM) is the unit of measure for this.

No matter how much water per minute you need, there are a few things to keep in mind. It takes roughly 2-3 gallons of water every minute to take a shower, for example.  A higher production ratio is unlikely to be required as a result.

Aim for a moderate production in any case. Low water pressure is a common problem for recreational vehicles, which means that many of them do not have excess capacity.


On the other hand, some of the options on this list had multiple filters. This has the obvious advantage of giving you a lot more mileage. While a two-pack is more expensive, it will likely save you money in the long run.

Expected life expectancy

The lifespan of a water filter is influenced by a number of things. Personal use is clearly the most crucial factor to consider. When it comes to filters, the more you use them, the more often you’ll need to replace them.

As a result, this is frequently only detected after you’ve observed foul-smelling water flowing out of your sink.

When it comes to replacing your filter, most manufacturers provide guidelines on how often you should do it. Three months to a year is a common timeframe for these assessments. In the RV, on the other hand, you are likely to use a lot less water than you would in your home.

The amount of gallons of water a filter can process before it needs to be replaced has become a standard practice for several companies. Take a shower, for example, and you’ll use about 17 gallons of water.

When combined with a little bit of arithmetic, figures like these can help you develop a more accurate time frame of your life based on your everyday habits. A longer lifespan filter costs more, but it saves you money over time.

Hardware and housing

But that’s not all there is to it. On top of all of that, your product’s enclosure and attachment components play an important role in its performance.

A durable plastic housing is a good investment as it ensures that it will survive for the duration of its life expectancy Brass is widely used in hardware to prevent leaks and resist typical wear and tear.

However, housing materials may be reused and even compatible with filters made by different manufacturers, which is a blessing.


The performance of some water filters depends on the temperature at which they are used. This range is normally very broad, but it may be limited in certain cases. Such a filter could, for example, perform optimally between 30 and 100 degrees Fahrenheit

If you reside in (or want to visit) an area with a harsher climate, this may not be the best option for you to consider.

Treatments you desire

All water filters are not created equal. Therefore, you need to find out what the filter is capable of in order to make an informed decision.

Listed below is a list of common contaminants found around the world, but particularly at campsites:

  • Sedimentation (sand, dirt, etc.)

There are usually limitations to the types of filters as well as the effectiveness of the filter. It’s not uncommon to come across filters that claim 99.9 percent efficiency in removing contaminants. Naturally, the more efficient your filter is, the better off you will be as a result of that fact.

Water Tension

In addition, some filters will mention that they must be used with a certain PSI level in order to be effective. A 30-60 PSI limit, for example, is not uncommon.

The amount specified by the manufacturer will usually be near to what your plumbing system is currently able to provide. The water pressure is already regulated for safety reasons since too high or too low may cause problems.

Make sure the filter doesn’t have any additional PSI requirements before using it to be on the safe side. A particular regulator will be required if this occurs.

It’s still possible to find great stuff for less, but if you use that as a starting point, you should be able to find mostly high-quality items.


Others must be placed under the sink in order to filter only drinking water, while others are connected to the pipe that enters your RV’s water tank.

Should I filter all of the water used in the RV or just the drinking water?

It all comes down to what you want from your RV water filter, as we discussed in the previous portion of this guide. People choose to either filter drinking water or water that’s meant for showers and cleaning.  It’s all a matter of personal choice, after all.

All of the water that enters my RV is filtered, in my opinion. As much as my health is concerned, I use it since it has been proven to improve skin, nail, and hair quality.

Therefore, I’ve always thought that filtering all of my water was the greatest option for my health and well-being. Getting a system that can accomplish this, though, will cost you somewhat additional money.

Finally, it comes down to weighing the pros and disadvantages of each method and choosing which one best suits your individual requirements.

What is the best way to clean an RV water filter?

Keeping your RV water filter clean is the easiest way to extend its life. To put it differently, cleaning your water filter more often decreases the frequency with which you need to replace it completely, and vice versa.

In order to clean a water filter in an RV, the first step is to backflush the filter. Cleaning the filter means running it in the opposite way from how it typically operates.

Some filters need you to manually reverse the flow, while others require you to use a backflush hose to remove any accumulated debris. To eliminate bigger particles that may be caked inside the filter, syringe backflushing is advised for the smaller filters. It is not necessary to use an air compressor for bigger filters.

Before backflushing your filter, if it has been dry for too long, let the water flow through it normally for a few minutes. Soak the components in water to wet them and release the hold of any germs or dirt on them.

Ceramic filters may need to be disassembled and manually brushed clean if they’re present in your water system.

A soft-bristled brush should be used to avoid harming the ceramic filter. If you’re unsure which brush to use, refer to the owner’s handbook.

Chlorinated tap water is used by some filter owners to clean their filters. In addition, this method is more efficient at neutralizing any minute bacteria or protozoa that have accumulated inside the filter while simultaneously washing it out with water.

The filter should be flushed with at least one gallon of chlorinated tap water if you use this method. Put a gallon of ordinary clean water through the filter before using it for drinking or dishwashing, and you’re ready to go!

As a result, you may be assured that your filter is free of extra chlorinated water. In the event that you are unable to access chlorinated tap water, you can manufacture your own using a mixture of plain tap water and bleach.

Do not exceed eight drops of unscented, transparent liquid bleach per one gallon of clean tap water if you opt for this choice.

Then, stir the mixture completely and let it sit for at least 30 minutes.

Next, backflush your filter using the bleach water solution that you’ve created. Just one more gallon of tap water (without bleach) should do the trick before reattaching your filter and putting your drinking water through it.

How long will an RV water filter last?

Depending on whatever filter you use and how you utilize it, the exact answer will vary. To their credit, the majority of filters are advertised as having a longer service life.

Filters can be extended in some cases if they are not used every day. Some filters last three months, while others last a year.

Though there are filters with long life spans, replacing them every three to six months if they are used regularly is typically recommended.

In addition, prolonged periods of inactivity can have a negative influence on your filtration system. Non-regular usage of filters with charcoal or ceramic components, for example, might cause them to crack and break. Using a filter with a broken component is not recommended.

How do I install (or replace) my RV water filter?

Installing or changing an RV water filter will depend on the type you’ve purchased, so be sure to read the instructions carefully.

Review your owner’s manual and follow the installation directions exactly before installing or changing an RV water filter. Meanwhile, inline water filters are the easiest to install of all types of filters.

In order to use them, you just need to install them in-line between the city water output and your RV’s inlet hose. In contrast, a canister-style water filter must be permanently installed under your RV.

For this sort of RV water filtration system to operate, it must also be connected directly to the water pipes, which will need extra plumbing work initially.

First, turn off the water supply to your equipment and empty the pipes. In order to avoid getting water in your RV’s underbelly compartment, remove any hose fittings before you start.

Check to see that your filters are placed correctly so that water flows into them in the right direction.  However, if you’re still unclear, you should always consult your user handbook.

Make sure everything is aligned correctly before connecting all hoses and pipe fittings and tightening them to ensure a leak-free system.

All fittings should be covered with the plumber’s tape to create a watertight seal. The filter may be installed after everything has been connected and checked to ensure there are no leaks.

There is a reduction in damage resulting from this, allowing the filter and its connections to last for a longer period of time.


If your concerns about these water filters haven’t been answered yet. The reason we are still here is that we’re not surprised. Here are some of the most often asked questions about RV water filters and how to maintain them.

Is it possible to use a water filter for hot water?

Answer: No, in a sense. When used with hot water, most of these filters will reverse the filtering process, enabling contaminants to return to the water.

As a rule of thumb, if in doubt, contact the manufacturer. After accidentally passing hot water through your filter, you may always fix it by immediately rinsing the filter with cold water for at least two minutes.

What is the best water filter in terms of taste?

That’s a tough one to answer since it’s so personal. You’ll get the best flavor from drinking water that’s been cleaned using a carbon and sediment filter.

Do RV water filters get rid of chlorine?

Almost all water filters for RVs will remove chlorine. While UV water filters do not, it is important to study the specs of the water filtration system before buying.

How do you keep RV water filters stored?

Due to their resistance to stagnation, they may be stored wet or dry. A dark and tidy place to keep the filters is all that’s required. Wet filters may be cleaned by removing water from their canisters and replacing them. Keep your CDB-KDF filters immersed in water if you have them.

Where is my RV’s water filter?

In some cases, your RV’s tank’s water filter is linked to a hose. Many of them may be put under the sink as well. In addition, your RV may include a filter in the tank as well as under the sink.

Do RV water filters remove chlorine?

The majority of RV water filters will eliminate chlorine. UV water filters, on the other hand, do not, so carefully read the specifications of the water filtration system before purchasing.
