Top 10 Best RV Water Filters

Best RV Water Filters

A quality water filter is definitely one of the most valuable RV plumbing purchases that you will make. Clean water is vital for good health, and since good RV water filters are not expensive, they can make a massive difference in the quality, taste, and smell of your water both at home and during your travels.

Of course, you should usually filter all of the water coming into the holding tank of your RV, anyhow, since this is the best means of ensuring safe, clean, sediment and bacteria-free water. Since it is rare to find pure water at every destination, a sound water filtration system for your RV or camper will provide you with safe, sanitary, and tasty water wherever you may roam. In this review, we will present the top 10 best RV water filters on the market right now.

First, Let’s cover a little bit of basic information about RV water filters. There are two types of systems.

Whole Water Filtration Systems:  These systems process all of the water that comes into your RV. Inline units that combine carbon filtration plus sediment removal are prevalent in many RV water filtration systems. Taste and odor removal are pretty good with these, although the ability to remove sediment may be somewhat limited. Although they are compact, their flow rate is limited, and they have a shorter life span. Still, they may be more than adequate for those who only use their RV’s for infrequent travel.

Standard Canister Systems: These water filtration systems for RVs are definitely the most versatile option, especially for those who are traveling full-time. This is because they typically have a much better water flow rate, and they will last longer. Also, you can configure and customize these systems to your own needs. 

Best Water Filters for RVs and Campers

Understanding the jargon used when talking about filters will also help you make a confident and well-informed choice. So, before we look at our list of the best RV water filters, here are a few terms to familiarize yourself with:

  • NSF class I, class II, class III: The National Sanitation Foundation uses these ratings to denote the efficiency of RV filters. For example, a Class I filter will remove chlorine from your water most efficiently. After class I, you have class II filters, which are not as good, then class III filters, and so on. 
  • Flow rate: Although you will need a filter for clean water in your RV, they, unfortunately, interfere with the flow. The amount of water (in gallons per minute) that your filter can handle is called the flow rate.
  • Microns: Microns are measurements of the size of particles filters will remove
  • Life expectancy: RV water filter cartridges will eventually become clogged. 
  • Life: The life of your filter indicates how much time you can reasonably expect it will last. Eventually, RV water filters get clogged and need to be replaced.
  • Material: This indicates the material used to do the work of filtering the water.
