When you travel around in an RV, even if you’re doing it part time or on the weekends, you’re going to be changing water sources at each location you go to. You won’t necessarily know what the quality of the water is or whether chemicals have been added to the water. Since you’ll be taking in water you may not be familiar with, it’s best to filter your water before you drink it.

For an RV there are several different ways you can go about filtering your water.
The Camco TastePURE Inline RV Water Filter is probably the filter we see most often around the campgrounds. These filters are large capacity filters which last on average 3-6 months. It’s a 20 micron sediment filter so it removes particles greater than 20 microns. If you’re more of a weekend warrior this system would probably work just fine for you.
The Dual Water Filtration system is another option. The one we specifically have is the Beech Lane External RV Water Filter System. This system uses both a 5 micron and 0.5 micron filter in order to filter both large particles like sand and dirt as well as smaller particles like chlorine. The Beech Lane system comes with brass fittings, a mounting bracket, and two filters. At the time this article was written it only cost $60 on Amazon. One of the nice things about this filter is that you replace the filters when needed with any universal filters of the same size. Another option in the Dual Water Filtration category is the Clearsource Premium RV Water Filter System. This product is significantly more expensive. At the time of writing this it costs $275. Both have 5 and 0.5 micron filters. The main difference between the two (from what we can tell) is the mounting bracket is a little different and the fittings are stainless steel instead of brass. In our opinion not worth the $215 price difference 🤷🏻♀️ But as with everything, do your own research!
Reverse osmosis is another option for filtering water. Reverse osmosis is a popular option for many home owners, but for RVers may not be the best option. Reverse osmosis is not a quick process and this slows down the water flow, which is why these systems have tanks where filtered water is stored. The system also takes up a good amount of room and would most likely need to be stored somewhere under your kitchen sink. While this type of system can remove anywhere from 95-99% of total dissolved solids as well as chlorine and fluoride it can also remove beneficial minerals such as magnesium and calcium. 
Another option many Rvers like to use for water filtration is the Berkey Water Filter. This filtration system is a stainless steel system that sits out on your countertop. It has a spigot for easy access. While this may be a good option for many, for us personally we don’t want it taking up the extra counter space. Plus there’s the fact that it just adds another thing that needs to be stored away on moving day.
In addition to the dual water filtration system we have on our RV, we also use a Pur Water Pitcher that we store in our refrigerator. They also make faucet filtration systems which fit onto your faucet as well.
Water is such a vital part of life so it’s definitely important to use a filter that is going to get you the cleanest water possible. If you have questions about our water setup or have a water filtration system we missed, let us know in the comments!
