Types of RV Water Filters

There are several types of water filters available to you. Some last longer than others, and some excel at different things. Here we will take a look at all the different types of water filters so that you know what to look for in the future.

Sediment Filter

A sediment filter captures and removes particulate matter like dirt and debris from your water. Sediment is a term that refers to any matter in your water that is not liquid. It is one of the most essential water filters that you can have in your RV. It is responsible for filtering out all the dirt, salt, and sand that can get into your water.

They are especially important because rainwater can carry silt, clay, soil, and sand. If you are using a well as one of your main sources of water, it is very likely that these things will get into your water. As a result, you need your water filter to ensure that your water is clean, and it is safe to drink.

Carbon Filter

A carbon water filter removes contaminants from the water via absorption. The filter absorbs particles to the surface like a piece of Velcro. Organic compounds will then bond or stick to the surface of the water filter and be removed from the water itself.

Carbon filters are very large and are great at reducing bad tastes and odors that can come from certain particles getting in your water. With its large surface area it is very effective at removing organic chemicals that could make your water toxic.

Ceramic Filter

A ceramic water filter uses tiny pores on a small ceramic surface to remove bacteria from your drinking water. It is a very affordable option and can be installed in any household, RV, or trailer. It can also be used as a portable filtration device. A ceramic water filter uses a natural ceramic media as the most significant portion of the filtration device. This is where the water is processed, and contaminations are removed from the water. Ceramic filters can be used in a variety of situations and they can use several methods to remove contaminants. For example, they can be gravity-fed, under-sink, countertop, or sometimes they can even be used for an entire house.

Reverse Osmosis

Reverse osmosis is an alternate method for removing contaminants from the water you use in your RV. What happens is water flows from the more concentrated side or the side with the contaminants through an RO membrane to the less concentrated side. When the water passes through the membrane the contaminants are removed and you should be left with clean drinking water.
