The Best RV Water Filter For Camping (2021)

As you travel across the country with your RV, you will encounter different water flavors. Every campsite or location will use a unique water source, which is why it’s essential that you and your family have access to safe, clean drinking water. A quality RV water filter allows you to enjoy the benefits of water without sacrificing your health or your travels.

What Is the Goal of an RV Water Filter?

The purpose of an RV water filter is to remove sand, dirt, and metals from the vehicle’s water supply. Advanced RV water filters can remove undesirable microscopic contaminants too.

Campsite water quality will be unpredictable. Various places will have healthy city water that goes through regular testing. Other locations will have water from an unknown location. Regardless, your RV water plays an essential role in delivering clean drinking water for you and your loved ones.

RV water filters do more than clean your drinking water. They also ensure that your whole water system is free of the contaminants that come from unhealthy sources. The sediment can get stuck in the pipes, which will infect the RV water pump filter or system. Without a reliable RV water filter system, you may experience unhealthy water, obstructed pipes, and further damage to the toilet and other facilities.

RV Water Filter Benefits

RV water filters offer three trusted benefits: water quality, appliance protection, and resistance against microscopic contaminants.

Because the filter eliminates contaminants and chlorine, it will elevate your water’s taste. You can drink your water with peace of mind knowing that the water filter system is doing its job correctly.

If sediment gets into the RV pipes, it can cause further damage when left untreated. Dirt and soil buildup can cause your appliances and plumbing to clog up. This obstruction will lead to other issues that will ruin the camping trip.

Lastly, an RV water filter keeps your family safe from dangerous chemicals and microorganisms. With a consistent water filter, you can drink from any water source. A camping trip will take you everywhere, and the RV water filter is designed to address any type of microorganism.

Water Filtering Methods

Before we dive into the different RV water filters, you must consider where the system will go. There are three approaches to positioning the RV water filter system: internal, external, and hybrid.

Internal Water Filter

You can install most RV water filters inside the RV. Placing them on the interior will reduce the space they take up on the inside. The best place to install the filter is right inside the location where the water infiltrates the RV. This strategy allows you to quickly locate the filter if you need to change it out. Also, you can efficiently monitor the filter for any leaks or defects when it is in a conspicuous spot.

External Water Filter

When you install an external filtration system, you can place it on the hose directly. Make sure you position it on the hose that carries the city water into the RV. This filtering system is straightforward and will do an excellent job of cleaning contaminants.

Hybrid Water Filter

Many RV owners utilize a combination of the methods described above. The external water filter would serve as the basic level of filtration. The internal water filter will usually be a more advanced water filter for kitchen sink water. Not only does this approach maintain water cleanliness, but it boosts the quality of your drinking water.

Types of RV Water Filters

There are many RV water filter types that you can choose from. It is essential to consider how many people will use the water and the size of your RV.


A countertop filtration system is a portable option that will filter the water right at the source. Brita pitchers, kitchen sink filters, and countertop distillers are all excellent options. Countertop water filters are not only cost-effective, but they also address different types of water sources. The only downside is that they take up critical space within the RV.


Inline water filters are placed on the exterior of your RV. They sit between two critical spots: the hose connection to the campground water and the junction where the water enters the camper.

The best thing about an RV inline water filter is its ease of use and installation. Not only are they simple to install, but they are easily replaced and transported. Inline RV water filters are an ideal solution for those who travel or camp on a part-time basis.

One drawback of the inline is that you will need to replace it often. As inline water filters near the end of their useful life, they will typically produce a lower water flow rate.


Canister filters are a more advanced solution than inline because the water goes through multiple filter types. The RV owner has the choice to customize the filtration system to his or her choosing. One canister may be designed to remove particles, while another is dedicated to eliminating chlorine. You can also install canister filters on the inside without worrying about the hookup.

One downside of the RV water filter canister is that the filters need to be changed regularly. Leaks and damage may also be tough to notice if the filter is in a hidden spot.

Other Things to Consider Before Purchasing an RV Water Filter

Besides the water filter method and type, here are some other critical factors to consider before purchasing your next RV water filter:

  • Micron Rating: communicates the particle size that the water filter will let pass through the system. For example, a filter that offers 0.1-micron water will remove more particles than a product with a 2-micron rating.
  • Amount of use: full-time RV owners will need a filter that is stronger and more long-lasting than someone who travels on a part-time basis.
  • Ease of use and installation: if your experience with installation and plumbing is limited, it would be best to select a product with a straightforward setup process.
