Camco 40045 TastePURE

  • Micron Rating: 20 Microns
  • Material: KDF and carbon

Camco is a popular RV parts brand because it makes good products, so if you're looking for the best RV exterior water filter you can lay your hands on, then here's an offer to check out.

The in-line design offers a high flow rate with its 20-Micron rating. It removes an extensive range of contaminants including bacteria, sediments, chlorine, Aluminum, heavy metals, and lots more, thanks to its KDF and carbon filtering technology.

For its downsides, Camco offers different packages. So, you can either get a package of 1 filter and a hose or 2 filters without a hose. It's also a temporary filter, so it comes with a 3-month average lifespan.

On the brighter side though, it delivers a high volume of clean drinking water from any conventional tap and if you're not satisfied with the flow rate, you can always opt for the extra-large filter.


  • Quickly & easily delivers clean and safe drinking water
  • Easy to install and use
  • Removes an extensive range of water contaminants
  • Available in different package options


  • It's temporary and only lasts about 3 months
  • The 2-pack option doesn't come with a hose

2. Camco 40631 EVO RV Water Filter

Camco 40631 EVO

  • Micron Rating: 5 Microns
  • Material: Polypropylene, KDF, carbon

Here's another Camco RV water filter but this one features a replaceable cartridge, making it a longer-term filter than the other 3-month temporary filter.

You'll still need to change the cartridge though, and they come at a cost, but you get a more stable filter with this offer, which is especially great if you want to install it permanently in a particular place.

For downsides, this filter costs more than the temporary models, plus it's rated 5 Microns, which means it has a slower flow rate than the 20-Micron models.

Camco includes an extension hose and an extra cartridge in this offer, although you'll need to buy the mounting brackets separately if you need it. This filter easily attaches to any standard tap or hose connection.


  • Premium RV filter with replaceable cartridge
  • Reduces bad taste, odors, chlorine, bacteria e.t.c
  • Attaches to any standard tap or hose
  • The package includes a hose and a replacement cartridge


  • Costs more than temporary models
  • Its 5-Micron barrier makes it slower than 20-Micron filters

3. Culligan RVF-10 RV Water Filter

Culligan RVF-10

  • Micron Rating: 5 Microns
  • Material: Carbon

Culligan also makes one of the best RV in-line water filters with this RVF-10 offer. The filter uses a replaceable cartridge to filter out contaminants and deliver safe drinking water.

It will remove sediments, odor, tastes, and Chlorine from the water using its carbon-impregnated 5-Micron cartridge filter. You should keep in mind, however, that 5 Microns means a slower flow rate.

Another con is that this filter lacks other filtering agents, so it won't filter many metals and chemicals, and you'll need to remove the cartridge when not in use, to dry it and prevent bacterial growth.

The package also includes a hose installation kit, but without a hose. Its D-15 cartridge has a 250 gallons or three months rating, and Culligan backs the package with a 5-year warranty.


  • Compact RV filter with replaceable filters
  • Its D-15 replacement filters are affordable
  • Installs easily with included kit
  • Backed by a 5-year limited warranty


  • Does not remove metals and other chemicals

It comes with a dual-stage filtration system that passes the water first through a 5-Micron sediment filter membrane before passing it through a second activated carbon membrane.

In the end, you get pristine drinking water that's free of cysts, Chlorine, giardia and lots more contaminants at an impressively fast rate of 6.5 gallons per minute.

The only problems are the high price of the unit and the larger space that it takes up, but if you want the best, then you've got to pay.

  • Offers a 5-Micron dual-stage filtration system
  • Features a metal chassis with stainless steel fittings
  • Clearsource backs it with a 1-year warranty

You get a blend of different filtrations materials, including GAF, KDF, and others. They then combine to remove an extensive range of contaminants, including heavy metals, Chlorine, Fluoride, and Arsenic.

The downside is that each filter comes rated to last at most about three months, but that's more on the lighter use side. With heavier use, they'll surely last way less than that. There's also no included accessory in the package.

How to Buy the Best RV Water Filter

How To Buy The Best RV Water Filters
How To Buy The Best RV Water Filters

RV water filters are special devices, so you'll need to understand their specific systems and technologies, to make an informed decision when making your choice.

There are different RV water filter types and they also use different filtration methods. There are also many similar technologies and specific terms that you'll need to understand.

All these important factors are below for your convenience.

1. Types of RV Water Filters

The first thing you should understand when it comes to RV water filters is the different filtration types available. These different types come as a result of the different materials used in producing the filters and the natural properties of these materials.

RV water filters come under three groups, namely sediment filters, activated charcoal filters, and ceramic water filters. Here's a look at each type of filter.

Sediment Water Filters. This is the oldest and most basic filtration system you'll find. It simply needs water to flow through a series of small particles that get stacked together and thereby rid the water of its impurities in the process.

If all you need is a simple filtration of your RV water, then a sediment filter can do the job, but as you can imagine, their success depends on the size of the sediments, as well as the depth of the sedimentation.

Activated Carbon Water Filters. This type of water filter also filters water using the same principle as sediment filters, but they do much more than that.

With an activated carbon filter, you'll additionally get rid of bad tastes and smells in your water, thereby improving its overall quality. They also filter lots of heavy and harmful metals, as well as volatile organic compounds that are often found in low-quality water.

Ceramic Water Filters. This type of filters use very fine ceramic as their filtration barrier and are very good at removing sediments and micro-organisms like bacteria.

Where ceramic filters fail is when it comes to chemical contaminants like chlorine and lead. They can't handle these chemicals that activated charcoal filters handle very well, so you'll often see a hybrid ceramic and activated charcoal filter that does the job perfectly.

2. The Water You Want to Filter

Also worth consideration is the water that you plan on filtering. You need to consider the amount of water that you need to get filtered and then plan on a capable filter system.

You'll also need to consider the type of water that you're filtering, as well as how clean you want the clean water. If you're filtering dirty water with sediments, for instance, then you may want to invest in a sediment filter that filters all the water in your RV.

If you want only the best drinking water on the other hand, then you'll want to consider a filter that removes biological and chemical contaminants as well.

Another possibility is installing a general filter for the entire RV and then a specific filter for high-quality drinking and cooking water. The final decision here, however, is all yours.

3. Micron Rating

Most of the RV water filters that you'll find come with a micron rating and it's important that you understand what it means. A micron is a micrometer and equal to a millionth of a meter.

A filters micron rating tells you how small its holes are and this is important because smaller holes filter more contaminants, although they may work slower than filters with larger holes.

4. Size

This one is on an individual basis because you need a filter that fits the water needs of your RV. Remember that a larger filter produces more water flow, while a smaller filter produces less water.

There's no single answer here, except that you should get the largest filters that can fit into your rig because the water flow slows down with time due to sedimentation. You'll need to clean out the filter or replace it at one point.

5. Ease of Installation & Use

You'll be changing your water filter after about 3 months, so you need to consider getting a water filter that's both easy to install and to use, for your convenience.

6. Brand & Price

Top brand products may seem to cost more but they often offer better value than cheaper products. Here, it's left for you to find your balance between brand, price, and quality.
