Recap: The Best RV Water Filters

Buying an RV Water Filter: What to Look For

Not all RV water filters are made alike. As with anything you purchase, knowing your needs first will allow you to shop specifically for them. With that, be sure to consider these following factors when you are looking for an RV water filter.

Type of Filter

There are a few different types of filters you can choose from.

Carbon filters

Carbon water filters are great at removing bad odors and tastes from your water supply in addition to contaminants like: asbestos, lead, mercury, and various organic compounds.

Ceramic filters

Ceramic water filters have small holes in them that filter out nasty stuff like sediment, bacteria, protozoa, and cysts. They aren’t as effective at removing chemical contaminants though.

Sediment filters

Sediment water filters are the most common filters in RV setups today. They do a decent job of protecting your plumbing and water appliances.

Reverse Osmosis

Reverse osmosis filters have a semi-permeable membrane that water passes through, which filters out anything bigger than a water molecule. These filters do a great job of blocking arsenic, perchlorate, flouride, hexavalent chromium, and nitrates.

Filtration Stages

Some RV water filters will only have one filtration stage, while others may have two or more. Having more filtration stages doesn’t always mean a filter is better than another. However, you want to take a look at what gets filtered in each stage. Many times, a second filtration stage in a filter is what allows your water to be free of unpleasant odors and tastes.

Purifying Your Drinking Water

Of course, with the water you drink, you may want the highest purification possible. With newer, more powerful units, you will find that ultraviolet light filtration systems can provide you with enhanced purification that targets and neutralizes microbes. You do not have to use systems this with all the water that enters your RV, but it is super beneficial for your drinking water.

Size & How Much Water You Want to Filter

The size of your filter can play a role in how much clean water you will have access too. Especially when you are on the road and not attached to your water source. If you travel with your family and will need more water, then you’ll want filtration systems that have larger cartridges.

The size of your filter will also be impacted by how much water you want to filter and the water pressure that comes out the other end. If you only want to filter your kitchen faucet water, then you will fare best with an under the sink inline filtration system. These are typically compact, and instead of storing water, they filter water as it passes through. When filtering all the water that comes into your camper, an exterior inline filtration unit would be the best. The size will also determine how often you need to change your filter cartridge.

Price Point

The price of an RV water filtration system will be all over the map. For RV users, this is a good thing because you will always be able to find a filtration system that meets your financial needs.
