Best RV Water Filter

[amazon fields="B074CNXQXQ" tracking_id="cotor-bg-best-rv-water-filter-20" value="thumb" image_size="large" image_align="center"]

The CLEARSOURCE is one of the most complete options on our list, able to do everything as well or better than any of the other alternatives that we reviewed. For starters, this is one of a few RV water filters that provide a true two-step water filtration process to remove multiple types and sizes of contaminants. Giving you clean drinking water, and removing most bad taste and odor.

On top of that, the CLEARSOURCE provides the largest flow rate on our list at 6 ½ ga, and the comparison is not even close. Even better, the CLEARSOURCE also tops our list in lifespan by being able to filter up to 2000 gallons of water before needing to change out the filters.

This water filter is reasonably easy to install for a two-step water system and uses universal connections. Outside of the standard issue that most caravan water filters have with their connections, the only real concern with the CLEARSOURCE water filter is its price, which is one of the highest we saw.

Bottom Line: Unless you plan on carefully restricting your use of multiple water sources and appliances, the chances are that the CLEARSOURCE’s massive water flow and extensive lifespan makes it one of the best options.

Best RV Water Filter: Remove Sediments, Odors & Bad Tastes

With all of the different tasks and appliances, you need to account for, sometimes the most basic aspects of RVing can get lost in the shuffle. A prime example of this is water, potable, or otherwise, especially since it is not difficult to get for an RV.

However, while getting water for your RV may not be a problem, making sure that the water quality is as it should be can be an issue. With RV parks and other camping locations not always maintaining the best plumbing system, you may want to improve the water quality of the water company’s filtration with some of your own.

That is why we put together a list of the eight best RV water filter reviews, detailing each filter’s particular strengths and uses. We also provide a helpful buyer’s guide, so you can figure out which is the best water filter for your RV’s needs.

Why You Should Use an RV Water Filter

Clean water is essential for every living thing, and while most municipalities do a decent job ensuring the city water is safe to drink, things can get a bit less reliable when traveling on the road.

Even in an RV campsite, there is no guarantee that the city water is clean because most RV parks do not change out their pipe systems regularly enough.

Even outside of drinking water, it is vital to make sure you have clean water for a wide variety of purposes, including cooking and cleaning– both yourself and your possessions.

Different Types of RV Water Filters

The type of RV water filter you should choose depends more on the particular issues your source water faces. Most basic RV water filters focus on contaminants like large particle sediment, heavy metals, harmful chemicals, and common bio-organisms.


An inline water filter connects directly to the appliance and only filters water used by that appliance. This kind of filter is handy if you have few appliances in your RV and is also a bit less expensive than more robust water filtration systems.

However, inline water filters are not as good if your RV has multiple sinks, showers, and other water appliances.


Canister water filters generally connect to your RV’s main water supply and filter the water for multiple appliances– if not all of them. That said, smaller canister water filters can also serve as inline filters for a single appliance, though this can be a bit pricey depending on the type of filter material used.

Reverse Osmosis

This is the best kind of water filter to decontaminate the water from organic compounds and incredibly fine particles. That said, reverse osmosis systems are also usually more expensive, take up more space, and are more challenging to install.

Carbon Filters

Carbon filters serve a couple of purposes, but they primarily act as medium-sized particle filters. This includes anything from sediment to volatile organic chemicals (VOCs) but does not usually include organisms. That said, carbon filters also do a decent job of removing contaminants that remove any bad taste and odor from the water.

Sediment Filters

While carbon filters can remove larger particles, they tend to lose their filtration ability rather quickly if they do. Because of this, some of the better water filters out there include a special trap designed to catch only large particles like sediment.

Ultraviolet Purification

This is another excellent water filter is you need to primarily remove organic contaminants from the water. That said, UV water filters are not the best for eliminating sediment or inorganic compounds, though it is more environmentally-friendly than most other types.

Things to Consider When Buying a

Water Sources

Water sources refer to where you get your RV’s water from with sources in a town or other municipality generally have a better water quality than those pulled from wells. Keep in mind, the distance the city water has to travel from the water source can also play a huge impact as well.

Depending on what type of material the plumbing is made of and how old it is, perfectly clean water can become contaminated while traveling through the plumbing. If you park your RV somewhere in or directly adjacent to a town, you may not need as thorough of a water filter to obtain clean, drinking water.

For cleaner water, a basic carbon filter will often suffice by removing the chlorine taste and odor. For water gotten “off the beaten path,” look for a water filter that cleans sediment and organisms, especially cryptosporidium and giardia labia.

Water Pressure/Flow & Filter Size

The water pressure and flow rate are important as they largely determine how many water faucets you can use at one time, as well as how much water you can use from a water source before running out of water. Keep in mind, RV water appliances generally use fewer gallons per minute (GPM) than the average one found in your home.

For RV sinks, the average flow rate is about 1 GPM but can get as high as 3 ½ GPM for more robust models. Likewise, the average RV showerhead will have a flow rate of 1 ½ GPM but can get up to 2 ½ to 3 GPM.

For water pressure rates, you generally want to stick somewhere between 50 to 60 pounds per square inch (PSI). Any lower and you will not have enough water pressure to take a good shower while anything higher might cause damage to your RV’s plumbing— depending on the quality.

That said, since RVs usually only carry anywhere from 50 to 300 gallons of drinking water, it is often a better idea to use appliances with lower flow rates and higher water pressure rates. This arrangement can allow water filters with lower flow rates to still provide enough GPM for the water you use in your appliances.

In terms of “size”, the filters usually follow a standard size, though how much water they can filter before the cartridge needs to be replaced differs. Generally, filters meant to clean larger particles need to be replaced more frequently than those which filter finer contaminants.

Filter Material

Most water filters do not tell you the material of the filter outside of carbon filters. This is not a significant concern, though most water filter cartridges are made into some mesh weave to better trap contaminants.

Another common filter material used is kinetic fluxion degradation material (KDF), which is also known as copper-zinc filtration. This material removes heavy metals as well as chlorine and other chemicals that can affect the water’s smell or flavor.

A few RV water filters may also contain activated alumina media, which helps filter out fluoride, though you generally need a large amount for this to be completely effective.

Ease of Use and Storage

All of the water filters we reviewed use universal connections, which make them reasonably easy to install and use. For dual-canister water filters, look for models that include a special “canister wrench” to make changing the filter cartridge easier.

Likewise, storage is rarely an issue as single canisters are often 11” x 3” and dual canister systems include mounting brackets. Some single canister water filters do not come with a mounting bracket and will need to either be fastened separately or positioned so that they do not move.

Best RV Water Filters: The Results

Camco 40043 TastePURE RV/Marine

Best Hose RV Water Filter

Camco 40043 TastePure RV/Marine Water Filter with Flexible Hose Protector | Protects Against Bacteria | Reduces Bad Taste, Odors, Chlorine and Sediment in Drinking Water

The Camco 40043 TastePURE RV covers a lot of your bases, but one of the best things about it is how portable it is. For one, it is one of the more compact and lightweight models on our list without the need to permanently fasten it through installation.

On top of that, it also uses universal connections, which allows you to connect one end to a standard water hose and the other end to a standard nozzle. The Camco 40043 TastePURE comes with a high-carbon filter capable of removing particles of 20 microns.

That said, the Camco 40043 TastePURE does not come with a filter cartridge capable of filtering any smaller particles leaving best-suited as for filtering out sediment. Of course, you can always purchase a separate cartridge filter, but that might limit its versatility a bit.

Thankfully, the Camco 40043 TastePURE uses a KDF cartridge, so you do not have to worry about bacterial build-up when the filter is not in use.

  • PROs

    • Cheaper option
    • Is a 20-micron filter
    • Is a high-carbon filter
    • Has a universal connector
  • CONs

    • Functions mostly as a sediment catcher
    • Connections may leak

Bottom-Line: If you want a product to serve a couple of different purposes, it is hard to deny the Camco TastePURE’s versatility.

CLEARSOURCE Premium RV Water Filtration System

Highest Flow Rate RV Water Filter

Clearsource Premium RV Water Filter System | Pristine Water. Unparalleled Water Flow. Built-in Stand.

If you are comparing models by specs and capabilities alone, there is not much of a competition between the CLEARSOURCE and pretty much any other product that we came across. For starters, this is a two-step canister water filtration system, though it is not the only two-step model on our list.

Still, the CLEARSOURCE water filter first uses a sediment trap to screen contaminants of 5.0 microns or larger, then runs the water through an activated carbon filter to catch anything 0.5 microns or larger. Even better, the CLEARSOURCE uses stainless steel fittings, which resist rust better than most other types of materials while maintaining superior structural integrity.

Still, the most impressive quality of the CLEARSOURCE likely comes with its flow rate of 6 ½ gallons, which is almost twice as much as the next closest model on our list. It also ties our list for the longest lifespan, able to filter up to 2000 gallons before you need to change out the filter cartridge.

  • PROs

    • Contains a 5.0-micron sediment filter
    • Includes a 0.5-micron activated carbon filter
    • Has a 6 ½ ga flow rate
    • Filters up to 2000 ga
  • CONs

    • $$$
    • Connections may leak

Bottom-Line: CLEARSOURCE tops our list in all of the relevant specs, including flow rate and total gallons filtered with its two-step filtration process providing some of the cleanest water.

Culligan White Single Unit RVF-10 Level 1

Best Hot Water RV Water Filter

Culligan RVF-10 Recreational Vehicle (RV) External Water Filter, White, 250 Gallon

The Culligan RVF-10 Level 1 is a great product on our list for any task that requires the use of exceptionally hot water thanks to a list-leading maximum temperature capability of 125-degrees. Not only is this great for taking hot showers, but it also works well for cooking and cleaning purposes too.

It also does not hurt that the RVF-10 Level 1 uses universal connections, making it an excellent choice for hose and nozzle hookups– though it is not quite as well-designed for handheld use as some of the other products we saw. However, it may be a bit easier to control for this purpose since it comes with a button that controls the inlet valve.

It is worth noting that the Culligan RVF-10 Level 1 may not be the best for filtering potable water, as it is primarily a filter for sediments. Still, the activated carbon mesh has a lifespan of 250 gallons, and the body can accept any standard canister filter cartridge.

  • PROs

    • Has a maximum temperature of 125-degrees
    • Has a universal connection
    • Has carbon filtration
    • Filters up to 250 ga
  • CONs

    • Higher price point than some other models
    • Only sediment filtration system

Bottom-Line: The Culligan RVF-10 Level 1 tops our list for units that can withstand hot water temperatures.

Beech Lane External RV Dual Water Filtration System

Best Budget Dual RV Water Filter

Beech Lane External RV Dual Water Filter System, Leak-Free Brass Fittings, Mounting Bracket and Two Filters Included, Sturdy Construction is Built to Last

For those who want all of the benefits of a two-step system but do not have the money to spend on the more expensive models, the Beech Lane BL-113 is ideal. To increase its overall value even further, the BL-113 water filtration system also comes with a lifetime warranty, which is easily the longest warranty that we found.

Like many other two-step systems, the Beech Lane first runs the water through its sediment mesh to remove particles 5.0 microns and larger. Then, the BL-113 sends the remaining water through a carbon block filter that removes any particles 0.5 microns and larger.

While this is great, the Beech Lane also has a decent lifespan, able to clean up to 1900 gallons of water before needing its filter cartridge replaced. Though it may take a bit more installation, the BL-113 at least uses durable materials for the mounting bracket.

  • PROs

    • Contains a 5.0-micron sediment mesh
    • Includes a 0.5-micron carbon filtration block
    • Has a lifetime warranty
    • Filters up to 1900 ga
  • CONs

    • Connections may leak

Bottom-Line: That the Beech Lane can offer a two-step filtration process at such a low price is pleasantly surprising.

AQUA CREST RV Inline Water Filter

Best Multi-Source RV Water Filter

AQUA CREST RV Inline Water Filter with Hose Protector, NSF Certified, Reduces Chlorine, Bad Taste&Odor for RVs and Marines, Drinking & Washing Filter with 1 Flexible Hose Protector

The AQUA CREST could arguably be considered one of the best all-around values on our list if for no other reason than the fact that you get two different canisters for one of the lower prices on our list. On top of that, the AQUA CREST is one of the few products we found which uses a multi-stage filtration system inside of a single canister system.

Despite what it may seem, the AQUA CREST is not meant to be used as a two-stage filtration system. Instead, the individual canisters are intended to be used as water filters for two different water sources, like one for potable use and one for utility purposes.

One thing to consider is that AQUA CREST comes with a hose connector, but you will likely want to replace it as soon as you can. That said, this is the only product that we reviewed, which can filter fluoride out of your water on top of the more common contaminants.

  • PROs

    • Relatively inexpensive
    • Is a 20-micron filter
    • Comes in a 2-pack
    • Has a fluoride filter layer
  • CONs

    • Connections may leak
    • Has a poor hose protector

Bottom-Line: The AQUA Crest is not only one of the less expensive models that we came across, but it further increases its value by providing two canisters instead of one.

Culligan RV-800 Exterior Pre-Tank Recreational Vehicle Water Filter with Hose

Clearest RV Water Filter

Culligan RV-800 Exterior Pre-Tank Recreational Vehicle Water Filter with Hose

Culligan makes another appearance on our list, but this time the company focused on an issue more likely to plague RVers more than most: turbid, cloudy water. To make sure that was not an issue here, the Culligan RV-800 is the only one on our list that can boast a turbidity level of 5 NTU, which is the rating for clear water.

On top of that, the Culligan RV-800 also boasts a list-tieing lifespan of 200 gallons filtered before you need to worry about changing out the filter cartridge. Like the other Culligan, the RV-800 uses universal connections and is even easier to use portably too.

On the other hand, the Culligan RV-800 is meant primarily for cold water purposes and does not boast the high maximum temperature rating that the prior Culligan does. It is also worth noting that the RV-800 serves primarily as a sediment filter, making it best-suited for utility purposes.

  • PROs

    • Runs at the low end of the price spectrum
    • Is a 5 NTU turbidity filter
    • Can filter up to 2000 ga
    • Has a universal connection
  • CONs

    • Only meant for cold water use
    • Is primarily a sediment filter

Bottom-Line: The Culligan RV-800 focuses a bit more on the larger particles commonly found in questionable water supplies and clears them right up.

Watts POE12DSA1KDF Dual Exterior Water Filter Kit

Best Mid-Level Dual RV Water Filter

Watts POE12DSA1KDF Dual Exterior Water Filter Kit

Though the Watts may not be able to boast list-leading specs across the board, it does come in at least second-place and is less expensive than some of the other premium products we found. For example, this model has the second-largest flow rate that we reviewed at 3 gallons, which is generally more than enough for multiple simultaneous RV water sources.

On top of that, Watts uses a two-step water filtration system to remove more particles than most single-step products. This model includes both a sediment filter for larger particles as well as a KDF/GAC carbon filter for the finer contaminants.

On top of a high throughput rate and a solid filtration system, the Watts also impressed with a 12-month lifespan before you need to replace the filter cartridge. However, this is one of the few models that use plastic fittings rather than metal ones.

This leads to the unit leaking more than some of the other models we reviewed, which is a problem for most canister system products in general.

  • PROs

    • Has a 12-month lifecycle
    • Has a universal connection
    • Comes with a KDF/GAC and sediment filter
    • 3 GA rate
  • CONs

    • Is a more expensive product
    • Connections may leak

Bottom-Line: The Watts Dual filtration system is a solid mid-level option for a two-step product, especially if you run multiple appliances simultaneously.

Hydro Life 52141 HL-200 External Filter Kit

Best Mid-Level Single RV Water Filter

Hydro Life 52141 HL-200 External Filter Kit

When it comes to single-step models, you are often limited by the flow rate, which rarely exceeds 1 gallon. Thankfully, the Hydro Life HL-200 suffers no such issues with the largest single-step filtration system throughput of 2 ½ gallons.

On top of that, the Hydro Life ties our list for the longest lifespan before needing to change filter cartridges at 12 months. The HL-200 also uses a carbon filter cartridge with finer mesh than most other carbon filter cartridges to remove even more contaminants than some of its competitors.

The KDF/GAC filter is also easily replaceable with any standard filter cartridge fitting the canister system. Likewise, the Hydro Life HL-200 filtration system comes uses universal connections, though it is a bit bulky to be used as a handheld model for utility purposes.

Still, this is one of the few products on our list to use stainless steel fitting as opposed to brass or plastic ones.

  • PROs

    • Has a 2 ½ ga flow rate
    • Has a universal connection
    • Comes with a KDF/GAC filter
    • Has a 12 mo lifespan
  • CONs

    • Is a more expensive product
    • Connections may leak

Bottom-Line: The Hydro Life HL-200 may not be the least expensive water filtration system that we reviewed, but it might provide the best all-around value.
