RV Water Filtration Systems RV Water Filtration Systems can be a make it or break it on a trip. Water is the most useful resource on our planet while it covers 71% of the earth’s surface. Water is mostly in the ocean and seas but can be found in a small part in the ground (1.7%). While we are on the road, in an RV resort, or especially boondocking we need this resource to survive. To properly sustain life the human body must ingest between 0.25 and 2 gallons of water daily. (1 and 7.5 liters)

Water Filtration vs. Water Purification

Water FIltration is the process of removing particles that have not been removed by another process such as purification. Purification differs from filtration based upon the processes. Filtration is the means of flowing water through a filter such as sand or polymer membranes. Where purification is done by adding a chemical to disinfect the water, like chlorine.

The water filtration system used in most RVs or by campers and hikers uses a cartridge with a carbon filter. The water is either drawn through or pushed through the filter. The process reduces bacteria, sediments, chlorine, lead, mercury, and other minerals remaining in the water. These can be minerals that collect in the water as it passes through pipes and into the RV through the hoses.

RV Water FIltration

The Water Filtration System within the RV can vary in size based upon the RV and the need of the RVer. Some RVer prefers to have small single cartridge filtration systems. These are great for the person who only travels a few time a year. Theses smaller cartridges should be changed every year.

Larger Water Filtration Systems are for the full-timer. The people know as RV Nomads. They live in their RV and travel the country. These types of water filtration systems will need to be changed more frequently based upon there water consumption. The RV Nomad could be boondocking using the fresh water from the freshwater tanks. In this case, they may choose to add an inline filtration system inside the RV.

Some of the Water Filtration System will use an additional filter cartridge to extract additional minerals. The additional filter could use some type of water softener or additional commercial grade filter.

RV Water Filtration Systems

RV Water Filtration Systems The basic RV Water Filtration System starts at the spigot. A simple carbon filter is attached to the spigot using a short anti-kink connector about 4 to 6 inches long. Some people may opt to put the short anti-kink connector on the RV with the filter just prior to attaching to the RV. Either way is acceptable, just make sure you observe the directional arrow on the filter. These RV filters are designed to work in one direction.

If you notice your water is not clear there are a few reasons. Usually, it is found that the filter was installed in the wrong direction. Other issues could be associated with the pipes delivering the water to the RV resort, there could be a local water problem, and even an issue with the hoses from the spigot.

Best RV Filtration Systems

Before we discuss the best RV FIltrations System lets look at what we need to filter out. There are usually 4 real issues that cause dirty or unsafe water conditions.

  • Sediment: is the largest mineral needed to be removed. It can run about 100 microns in size. Wells and springs can be loaded with sediment. The sediment can clog up fixtures, hoses, and valves. RVs are designed to be little weight for traveling. This means that some fixture and valves are made of plastic which can build up sediment more rapidly than brass. Sediment is where the brown or grey color comes from in the water.
  • Silt: Slit is the granular minerals found in water. This can usually be caused be some type of leak within the system or poor filtration at a waste treatment facility. Silt can run about 50 microns in size and can make the water feel slippery. Silt can mostly be found in spring feed water supplies.
  • Bacteria: Bacteria and viruses usually are approximately 2 – 5 microns in size. These as usually caused be poor purification processes and came from fecal organisms within the water. They can cause infections and other stomach illnesses if ingested at high quantities. Don’t worry, they can be treated and filtered out.
  • Giardia: Is the smallest at about 0.5 micros. These are very commented in water and are small microscopic parasites that cause diarrheal illnesses. Some symptoms include nausea, vomiting, diarrhea, and dehydration. Giardia is caused by animal fecal matter in the drinking water>

When choosing a water filtration system do the research. Filtration systems are designed with various sizes of pours. The larger the pores, the more will be allowed to pass through. In order to trap more minerals from not getting into your water find a water filtration system that has smaller pores. This is easily done by reading the label on the filters.

RV Water Filtration Systems A common filter on most RVs is the Camco TastePURE Water Filter. This is a good filter for just the part-time RVers not looking to spend a ton of money. It comes with a short flex connection and is attached to the spigot or to the RV on the outside. It’s also a good idea that these filters be replaced a little more regularly about once a week depending on water use.

best RV water filtration systemsFor more regular RVer or Full-timers there is the Clearsource RV Water Filter System. This a more expensive and can be installed anywhere in the water line. It is designed to be used for an extensive period of time with a two canister system. The first canister is to capture the larges material like sediment. While the second canister is a carbon filter rated at 0.5 micros. This means I will grab pretty much everything listed above.


The Best RV Water Filtration Systems will depend on the user and the amount of money spent. We gave you a little oversight on the difference between water filtration and water purification. Then concluded with two of the best RV Filtration Systems depending on the need. While both are designed to give the user clean drinkable water. One is more for a disposable or and weekly use. While the second has replaceable cartridges in the canisters for more of the Full-Time RVer or seasonal campers.

We hope you got some good information. Please share and comment.

Looking forward to hearing from you.

    Having a good water to drink is part of a healthy living and purification of water or filtration of water before drinking or use goes a long way in keeping our body healthy

    RV Water Filtration Systems is good  for water filtration. but there is a question I will like to ask

    if notice that the filter was installed in the wrong direction and it is reinstalled.is it going to work properly again or there is some other things that will need to be change before use

      Thank you for stopping and leaving the comment. 

      Good questions. If the filter is installed in the wrong direction you should notice almost immediately. You could get some black or other discoloration in the water. This is due to the carbon in the filters. Yes, you can reinstall it in the correct direction. 

      As far as changing fittings or any fixture, No. The Systems come with everything you need to install if you purchase the start-up kits initially. Then its just a matter of maintaining by changing the filters. All the fittings and fixture that come with the kit will fit directly within the water line or hoses. The only thing you may need is if you are installing the system within a cabinet. You may need to add some basic piping.

    Thanks for this nice review on RV filtration systems. There’s always need for clean portable water especially when you own an RV and have no guarantees concerning water at the parks. Tha camco taste pure water filter would be a good buy. I do wonder, what I have to install this filter myself?

      Thank you, Louis, for the comment. Yes, these filters can nstalled by the RV owner or by a dealer. The cheaper inline filters are attached directly to the spigot when setting up the RV at a location. Very simple to do if you can attach a garden hose to a spigot, you can add the filter in the line.

    Hi, I have read your article very carefully and I have found here very useful information about water filtration system specially RV water filtration system, I was don’t know before what is the difference between purification and filtration system? Now I am clear about it, Thank you so much for writhe this type of article.

      Happy to have been of assistance Abdullah. I thought it was a good idea to start by clarifying the difference. I didn’t want the reader to think it was the same process. 

      Thank you for the comment.
