When you roam about the country in an RV, you experience changes from place to place. That includes the taste, quality and purity of the local water supply. RV water filters can be pretty basic devices that reduce or eliminate odors, unpleasant tastes and sediment, but some go a lot further than that—aiming to eliminate bacteria and viruses before they can reach the RV’s faucet and your drinking glass.

As with most things, you get what you pay for. The most basic RV water filter on our list starts under $30 while the most elaborate is $500. Besides your budget, you should factor in how often you use your RV, where you go and your experiences with unfiltered water in those areas.

Travelers who tend to go to the same campsites and just want to improve the taste of their drinking water will find the Camco TastePure to be the bargain solution. It offers easy installation, a flexible hose and 20-micron sediment removal at a very low price.

The Waterdrop Inline RV water filter is impressive for the level of filtration it offers at a fairly low price. There are four layers of filtration (non-woven fabric, Kinetic Degradation Fluxion, granular-activated carbon and another layer of non-woven fabric) that the manufacturer claims will filter out suspended solids, large particles, odors, arsenic, heavy metals and chlorine. It’s easy to install and durable, with a flexible, anti-kink hose.

The Frizzlife SP99 is a solid choice for a permanent water filter that doesn’t need to be installed with the supply hose or stored when in motion. It offers three-stage filtration and comes with an additional faucet, allowing users to simultaneously run hot water for dishes and pour glasses of cold drinking water. 

The Camco EVO is an inline RV water filter that bridges the gap between the lower-priced inlines and the more upscale filters. It offers a high degree of filtration, easy installation and sturdy construction, making its moderate price a great value. 

If you want to eliminate virtually all risks in the drinking water in your RV, the Clearsource Ultra is the answer. It offers three-stage filtration with a 5.0-micron filter for rust and sediment; a 0.5-micron coconut shell carbon-block compound for chlorine, volatile organic compounds and other contaminants; and a third stage to filter out both bacteria and viruses. Featuring rugged construction (the manufacturer uses the term “bulletproof”) and durable stainless steel fittings, this is a premium RV water filter at a premium price.
