If you own an RV or motorhome, or you are just a camping enthusiast, you know sometimes it is hard to get onsite clean water. In these places, water might contain sediments, debris, and even funny odors. That is why having a water filtration system is essential if you want to have clean water. The problem is not every water filter will get the job done.

So which is the best water filter for RVs, campers, and motorhomes? The best water filter contains the right properties for camping groundwater purification. They should be of the right micron size, filter water at the desired flow rate, and be durable. This will enable them to remove all manner of impurities including gunk, grit, debris, and bad odors from campsite hookups. 




Why RV, Campers, and Motorhomes Water Filter Is Important

For most people, the obvious purpose of the RV water filtration system is for drinking water purification. Of course, this is important as it is effective in filtering out a wide range of impurities, resulting in safer, healthier water, for every camper.

That aside, the RV water filter plays other roles as well. To maintain the RV or motorhome plumbing in good shape, having clean water is essential. Having unfiltered water eventually ends up clogging the plumbing system. And you know, a blocked RV kitchen sink or toilet is every camper's nightmare. You do not want disruption to your camping experience, in remote places with no plumbing technician within reach.

What Are the Different Water Filtration Options?

Just like acquiring the best water filters, connecting your RV water filtration system is equally critical. We will discuss three major easy-to-use options.


Internal RV and Motorhomes Water Filters

These are filters installed inside the RV or motorhome at the entry point of the utility water source. The obvious advantage is you can conveniently install it in a secure accessible location for easy inspection and maintenance. 

External Water Filters

This is also a desirable method of water filtration installation. Connect the filter to the hook-up point of the hose to the main water source. That ensures all types of impurities are filtered out at the source.

Combined Water Filtration System

This is a great method to use when you need a purer level of water filtration. It works by installing an external water filter to remove most of the major impurities. Then to the outlet of this filtered water, you can install a smaller micron rating filter to purify the water further. At this point the water purity level is high, and it can be safely used for cooking or drinking. 

What to Consider for the Best Water Filter

Not every filter is effective for an RV or motorhome. Here are some of the factors to consider when buying the best water filter for this purpose.


Micron Rating

This refers to the measurement unit of the impurities' particle sizes. It is the gauge the manufacturers use in rating water filters. Consequently, filters of low micron ratings are the best choice for the cleanest purification level.

Water Filtration Rate

Measured in gallons per minute, the flow speed of filtration is dependent on the micron rating of the filter. The smaller the rating, the slower the filtration rate. This results from lower pressure created by the fine impurities being forced through the minute pores. Knowing this rating will help in making the best choice considering the desirable water purity and the filtration flow rate.


With time most filtration systems will need replacement as they get clogged up. So buying the best quality means you will need fewer replacements. Be sure to only buy products from reputable brands, for your RV or motorhome water filtration system. 

The Best Choice Water Filter Types for RVs, Campers, and Motorhomes

Inline RV Water Filters

The inline RV water filter is installed outside of the camper along the hose connecting the water to the RV. This can be anywhere between the camp groundwater connection and the RV, or motorhome. Inline RV water filters are easy to install, maintain, and durable. 

But this can only happen if they’re quality RV filters from trusted brands. Nonetheless, they are a perfect choice for quick camping trips. 

Canister RV Water Filters

Unlike inline filters, canister water filters use more complex water filtration processes. This involves using multiple canisters to filter out different types of impurities. For example, with some models, it is possible to have a dedicated canister for chlorine filtration and another one for other impurity types. Also with canister RV filters, you can install them internally for easy monitoring and maintenance. 

Reverse Osmosis Water Filtration

This form of filtration is one of the most effective forms of water filtration. It works by pushing the impure water through a semipermeable membrane to filter out some of the smallest particles. 

However, even as it is effective in removing most impurities, it has a negative side. Due to the minute size of the filtration pores, only a small amount of water passes through. That means most of the water is considered impure and wasted. While it is a terrific filter,  you might not want to use it when water scarcity is a problem. 

Counter RV Water Filters

If for whatever reason you do not like any of the above, you can use the counter RV water filter. It is convenient and easy to use. All you’ve to do is to hitch it to the RV kitchen faucet, and the job is done.


Final Thoughts

Unclean water is one of the reasons people do not like camping and RV life. However, this needn't be the case at all. With quality water filtration solutions, you can have clean and healthy water in your motorhome or RV.
