Choosing the Best RV Water Filter System – A Roadmap to Clean Drinking Water


When you’re traveling in an RV, whether it’s for weekends or longer stretches, you encounter different water sources at each stop. Knowing the water quality or whether chemicals are present can be uncertain. That’s why having the best RV water filter system is crucial for safe drinking water on the go! Below we’ll explore several different RV water filter systems commonly used by RV owners.

RV Water Hose

Before we get into RV water filters, let’s chat about the critical first step in filtering drinking water for your RV: using the right RV water hose.

A regular garden hose just won’t cut it here! Ordinary garden hoses lack the safety standards needed for drinking water, potentially containing lead or materials that can leach chemicals into your water—definitely not what you want for your drinking supply!

When shopping for an RV water hose, ensure it’s explicitly designed for drinking or potable water. We’ve tested both the Camco Premium Drinking Water Hose and the Teknor Apex Zero-G RV hose, and while both work well, we prefer the Zero-G for its lightweight design and easy storage.

Pro Tip: It’s wise to add a water pressure regulator to your setup. This handy device helps maintain consistent water flow and protects your RV from potential damage caused by excessive water pressure. It’s a simple, yet effective addition to your water system that can make a world of difference in the long run.

Inline RV Water Filter

An inline RV water filter is a compact and convenient filtration system that connects directly to your water hose, effectively purifying water before it enters your RV. This ensures that you have clean and safe water for various uses inside your vehicle.

Camco TastePURE

One of the most common water filters you’ll find around the campground is the Camco TastePURE Inline RV Water Filter. This filter is designed to be connected directly to the water hose, ensuring that all water entering your RV is filtered.

The Camco TastePure uses a 20-micron sediment filter, effectively removing particles larger than 20 microns, including sediment, rust, and debris. While it may not address more complex contaminants like chemicals or microorganisms, it provides a good level of basic filtration suitable for many camping scenarios.

The filter has a large capacity and can last between 3 to 6 months depending on usage and water quality. Its simple design and affordable price make it appealing to weekend campers and full-time RVers alike.

Beech Lane Dual Water Filter

We personally use and recommend the Beech Lane External RV Water Filter System for its exceptional dual filtration capabilities. This system uses both 5-micron and 0.5-micron filters, effectively removing large particles like sand and dirt as well as smaller contaminants like chlorine. The Beech Lane system, complete with brass fittings, a mounting bracket, and two filters, offers a comprehensive solution at an affordable price point.

Reverse Osmosis Water Filter

While reverse osmosis (RO) is a highly effective water filtration method popular in many households, its suitability for RV use requires consideration. RO systems can remove up to 95-99% of total dissolved solids, chlorine, and fluoride, ensuring exceptionally clean water.

The trade-off is a slower water flow rate due to the intricate filtration process, often necessitating storage tanks for filtered water. This can pose challenges in an RV due to limited space, and the system typically needs to be installed under the kitchen sink. Additionally, RO systems remove beneficial minerals such as magnesium and calcium along with contaminants, which may not be ideal for everyone.

RVers should weigh the pros and cons carefully before opting for an RO system in their camper.
