Types of RV water Filters:

Sediment Water Filter:

The most basic type of the water filters is Sediment Filters that work like a strainer. They are best to protect the toilet valves, water pumps and water heaters as they can extract particles from the water.

But if compared to the other types of water filters, the sediment filters need more maintinance which makes them less recommendable than others.

Activated Carbon Water filters:

Activated carbon water filters are a good choice for RV owners as they clean water more than the sediment filters and improve the overall taste and quality of water.

They will provide you the pure safe water having no any harmful elements in it.

Ceramic Water Filters:

The third part of the water filters is Ceramic water filters, unlikely the sediment and carbon activated water filters, these filters use holes to filter the contaminants like bacteria, protozoa and the sediments.

Most of the latest models of these filters have now combined the carbon activated products with them so when you’re buying one, choose the one that has carbon activated filters components.

Things you need to consider when buying a RV water filter:

Micron Ratings of the filter

The micron rating is the standard for water filters to measure their performance of cleaning the water, the ratings are based on the size of the particles that a filter extracts and let pass.

The products with smaller micron ratings will filter more pollutants and contaminants from the water.


We consider price as a main factor whenever we buy anything, just like that you should have an idea that how much money are you going to spend on your RV water filtration system.

When you will have this clear in your mind, it will be easy and less time taking process to buy an RV water filter.

Water Usage

The main to consider when buying a water filter is you should know how much amount of water do you want to filter from the product.

When you will figure it out that if you want to filter only drinking water or the whole water that you use, you’ll have to spend less time choosing the right unit for you.

Size of filter

Before going to buy a water filter you should know what size do you actually need, if you want to filter only drinking water you should go for a smaller one but if you are willing to filter all the water that comes into your RV you should choose the big and most powerful one.

Easy to use product Anything we buy, we want it be simple and easy to use to avoid complications when out for a tour, so only go for a product that will be installed easily and will not be complicated when a filter replacing is needed.


How long the RV water filters last?

There can be some bad products that don’t last longer, but the good products will usually last for almost three months.
Some of the best products such as the ones we have combined above will last longer for three months or a whole camping season.

How can we install or change a water filter?

First of all, you should buy a unit with very easy installment process and then you should read the user manual and follow the instructions and you will see how easy it is to install a water filter. It mostly requires joining few pipes and tightening few screws.

Can a RV water filter be used for hot water?

There are no such cases we have seen before but most of the filters in my knowledge, are not meant to use for hot water, for more information you can contact the maker of the filter and ask them.

How to clean the filter?

As there are many different companies making a lot of designs of water filters, we cannot clean every filter on one method, for this purpose you must read the user manual and do how it is told there.


We hope that we have answered most of your questions that you wanted to ask about the RV water filters and our review helped you picking up a good water filter.
It is definitely only you who will make the final decision, hope you are now able to choose the one that best suits to your needs and will help you enjoy your RV tours.
