Water is essential to life!
Installing a quality water filter to your RV’s water system can give you the clean, fresh and sweet-tasting water that’s vital for your family’s health.
It can save you lots of dollars from not having to buy bottled water while you’re moving from campground to campground.
In this article, I’ll share with you the following 5 best RV water filters
How Do You Choose a RV Water Filter For Your Needs?
Depending on your area or the area of your chosen campground, you’ll face various levels of water issues.
Some areas have average problems and a simple water filter will cover your basic need for purified water.
Other areas are not so blessed!
Water with a foul smell and taste can come from a heavy metal overload, high levels of chlorine or sulfur content, or even poisonous contaminants.
For locations with highly contaminated water, you’ll want to consider filters that greatly reduce or even eliminate the impurities. Carbon or GAC filters with KDF treatments are excellent choices for bad-tasting and foul-smelling water.
For areas with high sediment levels, you may need to consider getting a dual grade filter cartridge.
What Exactly Is a GAC (Granular Activated Carbon) Filter?
Charcoal, which is a form of carbon, resembles a cross between graphite and a sponge.
See below video for a visual definition of activated carbon.
Its porous body is prime ground for luring and trapping contaminants like chlorine, pesticides and other poisonous solvents residing in your water source. A GAC filter has the ability to greatly reduce these contaminants from your water line.
Much like a sponge, this filter absorbs the impurities until it gets saturated to the point that it actually clogs and needs replacement.
Note with setting up a granular activated carbon filter, it’s advised to run the water through the filter until the excess carbon particles are washed out. Once the water runs clear, the filter is ready for use.
What’s the KDF (Kinetic Degradation Fluxion) Process Media?
The KDF55 is an ingenious design that utilizes science to bring healthy drinking water out of your kitchen tap.
You may have heard the age-old saying, “Opposites attract.”
This process does just that!
The alloys copper and zinc use their positive and negative charges to work together in attracting metals such as aluminum, mercury, cadmium, lead and arsenic. These metals bond with the copper and zinc to form a plate, effectively removing these metals from the water.
Some contaminants react by changing form and pass through the filter as harmless substances. Free chlorine is one such impurity; it changes into water-soluble chloride salt.
In this reaction process, copper and zinc chelates multiply in a controlled amount. They enter the water system as nutrients that are actually beneficial to the human body.
This whole process creates an uncomfortable environment for bacteria, viruses, and mold.
The KDF process is commonly used with GAC filters to enhance the performance of the carbon and reduce the bacteria growth while the filter is not in use.
When Do You Change the Cartridges In the Water Filter?
Most water filters are advertised to last through one camping season. More advanced water filters can last much longer than that. Cartridges still need to be maintained regularly.
Typically, full-time RVers will change their cartridges quarterly, or every 3 months.
High levels of contamination and sediment will greatly reduce the life of the cartridge in your water filter.
Here are two clues that your cartridge may be ready to be replaced:
1) The water flow has slowed down considerably
2) You begin to taste the chlorine or other unwelcome tastes again
It’s always an excellent idea to keep a close eye on your cartridge.
This Is Important About Your Water Filter
Remember that water expands when it freezes. In order to protect your water filter, store it safely in a warm place during freezing temperatures to prevent the housing from cracking.
Secondly, water filters are designed to make potable water healthier and more pleasant to drink. They’re not designed to make non-potable water, potable.

Which Filter Do You Prefer?
If you don’t mind changing the entire filter every camping season, you may want to consider the Camco TastePURE Water Filter which does an excellent job of removing metallic and chlorinated tastes and odors from the water.
If you don’t use extensive amounts of water and prefer to change only the cartridge instead of the whole filter, you may want to go with the Culligan RVF-10 Exterior RV Drinking Water Filter.
The Clearsource Premium RV Water Filter System may be what you’re looking for if you’re dealing with highly contaminated water and can afford a higher quality investment. The dual filtration system has a nifty built-in stand and produces clean, healthy and safe drinking water.
