What is the Best RV Water Filter?

The Travel Berkey Water Filter System is my top choice of the best RV water filters. Many RV owners turn to the Berkey as a reliable and robust option for purifying their drinking water. It uses reverse osmosis technology to remove particulates, bacteria, and even some heavy metals from your water supply and also includes additional activated carbon filters for extra protection.

What are RV Water Filters?

RV water filters ensure clean and safe water during recreational vehicle adventures. Water filters for RVers are designed to remove impurities, sediments, and contaminants from the water source, providing fresh and potable water wherever you go. 

RV water filters typically contain multiple filtration stages that eliminate contaminants, including chlorine, bacteria, viruses, heavy metals, and unpleasant odors or tastes. The best RV water filters employ a combination of activated carbon, sediment filters, and sometimes even advanced technologies like reverse osmosis or ultraviolet sterilization to deliver superior water quality. 

These filters not only enhance the taste and odor of the water but also protect your RV’s plumbing system by preventing clogs and buildup caused by sediment or other impurities. They come in various types and models, offering different levels of filtration and features to suit different needs. With these filters installed in your RV’s water system, you can have peace of mind knowing that you and your family are consuming clean and healthy water on your travels.

How Can RV Water Filters Benefit You?

Finding Quality Water Sources for RVs

When you visit a State or National Park campground, a private RV campground or even a Harvest Host location, they typically have a water source for your RV to hook into to have a direct water flow to your interior faucets. In traveling around the country, I know from personal experience and research that not all water sources are equal. Water quality varies a bit and, in some places, can even be toxic.

How to Choose the Best RV Water Filter for You

When searching for the best RV water filters, it’s essential to consider factors such as filtration efficiency, filter lifespan, and ease of installation. Look for filters capable of removing a wide range of contaminants with a long-lasting filter cartridge or replaceable elements. Additionally, opt for easy installation and maintenance filters, as this will save you time and effort on the road. Some popular options for top RV water filters include brands like Camco, Culligan, and AquaCrest, known for their quality and reliability. 

Investing in the best RV water filter for your needs ensures that your water supply remains clean and refreshing throughout your RV adventures, promoting a healthier and more enjoyable travel experience.

Buyers Guide: How I Conducted My Research 

As an experienced RVer, I’ve covered thousands of miles in my Airstream travel trailer and clean fresh water is one of my biggest concerns when I’m on the road. I explored each of these products and many more in detail before selecting the ones that best cater to my needs. Let me share with you how I considered various factors while making these choices.

I have a US Pure Water Filter at home, a reverse osmosis (RO) process. So in my research, I was looking to duplicate that system for use in my Airstream while traveling. That led me to find the Berkey travel filter and understand all the different systems out there. Naturally, As a newbie RVer, I certainly wanted a similar unit for my RV.


When conducting my research to find the best RV water filters, I started by considering pricing as a crucial factor. As an avid traveler, I understand the value of getting the best bang for my buck. I looked for options that offered a balance between affordability and performance. While some water filters may come with a higher upfront cost, I took into account their long-term value and durability. Additionally, I read through customer reviews and expert opinions to ensure that the filters I chose were not only reasonably priced but also had a reputation for reliability and effectiveness.


Next, I delved into the features offered by each RV water filter. Every traveler’s needs are unique, and so are the features required in a water filter. I sought filters that offered multiple stages of filtration, as this helps to eliminate a broader range of contaminants. UV sterilization features were also a plus, as they provide an extra layer of protection against harmful bacteria and viruses. An essential consideration for me was the filter’s flow rate, as some models may have slower filtration speeds, which can be frustrating when you need water quickly. I also looked for filters with easy installation and maintenance processes, as I prefer hassle-free solutions during my travels.

Potential Negatives

While evaluating the products, I made sure to take note of any potential negatives associated with each RV water filter. This included considering any limitations in terms of filtration capacity, filter lifespan, or compatibility with various RV setups. Some filters might require more frequent filter replacements, adding to ongoing costs. Additionally, I weighed the physical size of the filters to ensure they would fit comfortably in my RV’s designated storage area. Understanding the limitations of each product allowed me to make informed decisions, avoiding potential disappointments down the road.

Final Considerations

By conducting comprehensive research based on pricing, features, and potential negatives, I was able to select the best RV water filters for my needs. I now travel with confidence, knowing that I have a reliable water filtration system that provides my Airstream with clean and safe water throughout my journeys. Whether I’m camping in a remote wilderness area or parked at an RV resort, I can enjoy a refreshing glass of water, cook with peace of mind, and maintain the plumbing integrity of my beloved travel trailer. As an experienced RVer, I can’t stress enough the importance of investing in the best RV water filter to enhance your overall travel experience.

Wrapping Up

After traveling over 20,000 miles in my Airstream Travel Trailer and using these water filters I can honestly say that I’ve had very few issues with either the Berkey or the Camco. I write down my usage and change the filters based on the manufacturer’s specifications. It’s a small price to pay for having clean water while I’m on the road!

A primary inline RV water filter hooked up to your intake hose can make water suitable for daily chores and drinking. High-end water filters can even prevent health-related issues.

Should you drink the water directly from the tap?

Though you can drink tap water at RV campsites, over 30% RVers polled used some filter before they drank the water in their RV.

Where do you attach an RV water filter?

It is recommended that Inline RV water filters should be connected closest to the city water inlet. Most inline water filters come with a hose attachment to attach the filter to the channel.

How long do RV water filters last?

Most RV water filters will last about three months, depending on your use, and a high-quality filter could last up to 12 months.

What is a Micron Rating?

Micron ratings are the size of the openings in the filter. The larger the number, the more it allows through. Bacteria range from 0.2 to 2 microns in width/diameter and 1 to 10 microns in length, and viruses range from 0.004 to 0.1 microns. Insecticides can be 0.5 to 10 microns, and mold ranges from 10 to 30 microns.
