Any RVing trip requires access to clean, fresh water for drinking, washing dishes, cleaning up, showering, and even brushing one’s teeth. When you turn on the tap, the last thing you want to see is a brown stream that looks like something out of a horror movie. And not only is unclean, gritty water terrible for you, but it’s also bad for your RV’s plumbing system.

Although water quality varies from one region to the next, there is a remedy in the shape of an RV water filter.

Why Do You Need A Water Filter?

An RV water filter’s objective is to filter out particles like grit and sand, heavy metals, and even minuscule undesirable pollutants from your water source. Water quality at campgrounds may be all over the place, and it’s much worse if you’re obtaining your water from an unfamiliar water tap at a truck stop. Some areas have excellent municipal water that is tested on a regular basis but others have brown well water that is pouring through ancient pipes near the septic system.

There are regions where boil water advisories are in effect, and you definitely don’t want to consume any water that may be harmful. Washing dishes with contaminated water may be dangerous and unpleasant too so RV water filters come in handy in this situation.

Benefits of water filters

They make your water taste better by removing chlorine and pollutants and they help prevent clogs and damage caused by sediment accumulation in your pipes and appliances. Some of them can even protect you from hazardous bacteria too. Water filters are also a terrific way to save money and help the environment by eliminating the need to buy pricey bottled water – or waste plastic. Finding plastic recycling locations might be difficult depending on where you are visiting. Sit back and relax as we take you on a tour of the broad world of RV water filtration systems and purification choices, which vary from simple and budget-friendly to pretty darn sophisticated.

How To Choose The Best Water Filter

Micron Measurement

Microns are the smallest particles that can contaminate your camper’s water supply. As a result, all RV water filters will display their micron measurement, which indicates the lowest particle size that will be filtered out. The smaller the micron size, the more particles the RV water filter will filter out.

Flow Rate

While you may be tempted to get the smallest micron RV water filter system you can find, this will reduce your flow rate. Because it produces more resistance when water flows into your RV, a filter that removes more particles will lower your water pressure. That’s why the flow rate of all RV water filtration systems is specified in gallons per minute.


Filters in RV water filtration systems always need to be replaced. When selecting a water filter for your camper, look for this information to discover how often you’ll need to service your water filtering system.

Types of RV Water Filters

Inline Water Filters

Inline water filters are filters that are put outside your RV between the hose connecting to the campground water hookup and the point where the water enters your camper. Inline water filters are simple to set up, replace, and move, making them an ideal choice for part-time RVers. Inline RV water filters must be updated on a regular basis and will reduce your flow rate as they approach the end of their useful life.

Sediment Inline Water Filters

Sediment filters remove dirt and debris from the water, increasing the life of any downstream water filters and preserving your plumbing system from damage. If your water has a murky tint, generally brown or yellow, you need a sediment filter. It’s possible that if it tastes unclean, it’s because there’s dirt in it, therefore sediment filters can assist with flavor as well. A sediment filter is a must if you’re obtaining water from somewhere other than a normal municipal system.

Carbon Inline Water Filters

If your primary objective is to enhance the flavor and smell of your water, a carbon filter is a fantastic choice. Many campgrounds use city water that has been chlorinated and carbon filters eliminate chlorine’s taste and odor from the water you usually drink and use for washing. Chlorine and other impurities attach to the surface of the carbon block as water passes through the filter, preventing them from entering your RV’s water supply. Pesticides, herbicides, and other harmful substances are also removed from water by carbon.

Countertop Water Filters

A portable RV water filtration device that filters directly at the source is a countertop water filter. Special water pitchers, countertop water distillers, and kitchen sink water filters, for example, are all feasible water filtering systems for your RV or motorhome. These are easy, cost-effective ways for dealing with campsite water quality issues.

Reverse Osmosis Water Filter System

Reverse osmosis systems are regarded for producing some of the purest water. However, they waste a significant quantity of water in the process because these devices only allow the purest constituents of water to pass through so any impure particles are removed as waste. If you plan on boondocking, this is a huge issue because the wastewater created by reverse osmosis will quickly fill the grey water tank in your camper. You should only consider installing a reverse osmosis system if you want to use it for drinking water rather than for your entire water system.

Canister Water Filters

Because they pump water through multiple distinct types of filters, canister water filters are more sophisticated than inline filters. These water filtration systems for your camper let you choose the amount of filtration you want. Certain types, for example, allow you to have up to three distinct canisters with filters dedicated to various tasks. One canister may be dedicated to particle removal and the other to chlorine removal from your water. You may install a canister filter inside so you don’t have to bother wiring it up every time. Keep in mind that filters must be replaced, and leaks might go undiscovered if your RV’s water filter is situated in a difficult-to-see location.

Water filtration systems for RVs may appear to be complex, but if you know what questions to ask, the options become more obvious. Cleaning up filthy campsite water is necessary for each RVer, regardless of which route you take. Having clean water is one of the most important things you need when you are out on the road or at a campsite. Without it your entire trip may be turned upside down and that’s really not something anyone wants.
