Why do you need RV water filters?

We all have a reason to be concerned about the water we drink. No one is immune to contaminants in water and you can never be too sure about your water sources wherever you go like you are about your drinking water at home. Water is bound to have contaminants like pesticides, chlorine and chlorine by-products, aluminum, ammonia, copper, lead, silver, bacteria, viruses, and others. This is why an RV filter is one of the most important tools you can have as you travel.

Filters eliminate such contaminants from water, leaving us with clean and safe for drinking. Filtering also removes odor, bad flavor, and turbidity from water so that your water can taste great and have no smell as you drink.

Types of water filters systems for RV

Water filter systems are different from water filters. Filters are a component of the entire system. Here we highlight different types of water filter systems. Remember, it is possible to use a combination of filters in one system.

An inline water filter system

RV inline water filters, just as their name indicates, are installed directly on the RVs water-source. They filter out sediments while also eliminating bad flavor and odor in water.

Reverse osmosis water filter system

The reverse osmosis system is, apparently, the most expensive yet the most effective water filtering systems. However, bottled water remains the most expensive and perhaps environmentally unfriendly source of drinking water.

This system uses a semipermeable membrane to filter out any contaminant particles larger than water molecules. The pressure is used to force water through this membrane eliminating almost all contaminants to leave your water pure. While it may not filter out chlorine, a reverse osmosis system integrated with a carbon filter will do this quite well.

Canister water filter system

This is the most common and the best water filtration for RV. a filter is placed inside a plastic housing. Water is pushed through the canister to another or to its exit (if it is a single-canister system) using a pump.

Generally, these systems are less expensive compared to the reverse osmosis types. This is because it is only the cartridge that needs replacement when worn out. There are three main types of canister water filter systems available in different sizes:

  • The single canister system. Uses one filter to filter your water. The filter may come with a combination of cartridges for effective filtering.
  • Double canister system. Typically has a sediment filter as the first-stage filtering and a carbon filter in the second and final stage filtering.
  • Triple canister system. This system is more like the double canister system in its first and second filtration stages but with an additional special filter for its last stage.

Some advantages with this type of water filters are that they are customizable because you get to choose the filters to put in them, they are durable, and offer excellent flow rate.

Buying a water filtering system for your RV? Consider these

Apart from the type of water filter systems highlighted above, here are the factors you need to consider when buying a water filter system for your RV.

Type of filters. There are different types of filters from the most basic sediment filter which filters out particles, carbon filter which filters out chlorine, metals, chemicals, and other contaminants for better-tasting water, and ceramic filters which eliminate bacteria like cryptosporidium, and giardia as well as viruses and other microbes. There are different types of carbon filters to suit different situations including

  • Granular activated carbon (GAC) filter
  • Solid block carbon (SBC) filter
  • Modified carbon block (MBC) filter

The amount of water you intend to filter. Get a filter that matches the quantity of water you intend to filter. You may want to filter all or some of the water. This depends on the state of the water. If you expect the water to have a lot of dirt or sediment, consider filtering all the water. This will require not only carbon filter but also sediment filter to eliminate both sediments and chemicals in the water.

Filter size. The size of the filter you purchase will determine the amount of water you can filter. While the larger filters will filter out water fast, they are bulky, heavy and will require considerable storage space.

Micron rating. Some sediment filters are rated 5.0 microns to filter out larger particulates. Others are rated 1.0 microns while still others are rated 0.5 microns. A lower micron rating means that a filter will eliminate the finest contaminants in water.



Best RV Water Filtration Systems 2024

Considering the above factors takes you a step ahead in making your selection. However, it may still take you time sorting through the number of water filters available in the market. This is why we took the time to research some of the best RV water filtration systems. Check out what we came up with.

The two-stage filtering system is something to think about, particularly if you are not too sure about the kind of water you will find in your destination. The first stage features a 5.0-micron sediment filter which eliminates just that, sediments and other such-like particles. The second stage is the 0.5-micron filter featuring a coconut shell carbon block filter. It takes care of any pesticides, chlorine, giardia, cryptosporidium, and other deposits in the water. It is also the stage that improves the taste and smell in water making it not just safe for drinking but also great-tasting.

This system features a sturdy powder-coated metal chassis which holds the 2.5 x 10 inches canisters, stainless steel fittings, and buttress threading secured with o-rings that seal the filters tightly to the canisters to guarantee not just durability but also easy installation and safe operation because the fittings do not rust. Well, if you are in for the premium features, you’re in for the price.

It is one of the few filters that stop lime from forming on your electric kettle and other equipment by lowering the concentration of salts and metals which harden water. Its housing is made of premium quality plastic with the canisters each having an anti-slip base to keep them stable on the ground. The cartridges might need replacement twice a year depending on the quality of water that they filter.
