Best RV Water Filters

You’re not always going to get the best quality water when you’re traveling in your RV. However, you can ensure that your water is a little fresher and safer if you take the time to add the best RV water filters to the equation. The Camco TastePURE Inline RV Water Filter is an impressive option to include in this situation, but the better idea would be to take a look at our list and see which ones work for you.

Camco TastePURE Inline RV Water Filter

The top RV water filter that we’re going to review comes from Camco, a famous brand for all things having to do with RVs. The most interesting thing about this product is that it’s an inline water filter, meaning it’s actively installed in your system. While that can be difficult for first-timers, it’s worth not having to worry about it after you’re done.

This product is very inexpensive, and it can cut down on a lot of negative things like chlorine tastes, bad tastes, odors, and more. This will cut down on bacteria growth, too. The product comes in a two-pack and it’s very inexpensive considering that they will last for 3 months each. The product is also compliant with all levels of low lead laws, and it has a 20-micron sediment filter. All in all, this is a fantastic product for you to consider using.  

Clearsource Premium RV Water Filter System

Another great option on the market is the Clearsource water filter. This product is made to be very tough, and it has a 0.5-micron carbon block that will filter out all but the toughest issues. It’s rated to be significantly better than most water filters, and you’ll pay the price for that level of protection. This is a very costly measure that comes with the immediate benefit of giving you clearer water while also being easy to install.

If you can hook up a water hose, then you can use this product. It comes with steel fittings that will allow you to get a lot of use out of the filter. You will get three levels of filtering by using this product, and it is good for 2000 gallons of water!

Culligan RV-800 Exterior Pre-Tank RV Water Filter

Culligan is another exterior water filter that will work for your RV’s needs. It can connect to just about any recreational vehicle you can come up with, and it’s very easy to install for regular joes. You can get this with or without the connector hose, and it will still be an inexpensive option. The filter life is for 2000 gallons, more than enough for 6 months on average.

It will filter out chlorine tastes, water odors, bacteria, and dirt. While this is a good water filter, it’s not going to filter out everything like some more severe filters. Still, it’s a good option if you frequently go to trustworthy camping grounds to get your water sourced. Lastly, it comes with an IAPMO certification.  

Watts POE12DSA1KDF Water Filter

The Watts filter is another very good option that you can utilize. Like most, it’s very easy to install on your RV, so just about anyone can do it. This is a good but expensive option that hooks up to the outside of your RV. It will take care of most smells and contaminants. This product is about as effective as some of the inline ones but comes at a much higher cost.

So, it’s a matter of your comfort with inline vs. exterior that determines whether this is the product for you. It does have a high holding capacity, and it’s good for protecting against inorganic contamination that won’t even make it to the main filter. It lasts about 6-8 months according to the brand, which could break down to a long time depending on how much water you use.

PureDrop Aquacube 4-Stage Compact

The PureDrop Aquacube is another very good choice that you can make when looking for a water filter on your RV. This one is used from under the sink, so it’s not going to filter everything coming into your RV. Instead, it’s a good option if you’re trying to get clean drinking water in your sink. This is a four-stage filter that will break down everything to 0.1 microns.

That means you will be left with very clean, fresh-tasting water without the odors. If you use this in conjunction with your typical water filter, then you’ll get a great item with a 0.3-0.5 GPM flow for drinking water. If you want this level of clean water, though, you’ll have to pay for it since it’s expensive. Still, it might just be worth it to you.

Frizzlife Under Sink Water Filter

The Frizzlife Product is another water filter that you can use under your sink in the RV to give you access to fresh, clean water with ease. This filter comes with a lifespan of 6 months, and it’s something that most people can install on their own. Even the replacement cartridges are simple to use.

This product is less expensive than the last one, so it’s middling. It will filter heavy metals and everything else down to 0.5 microns. It has an auto-off feature that will help you conserve water, too. All in all, this is a solid choice for water filters.


When you’re looking at available water filters, you have to think about how much water you use and how good the water is at the source. Some of these are reasonable precautions and some might be overkill. Still, you can’t be too safe when it comes to drinking water and the water you run over your body.
