One of the most important preparations for any successful RV camping trip is ensuring you always have a supply of clean water. One of the ways you can accomplish this is by ensuring you carry clean drinking water in your RV fresh water tank when you leave home. However, this may not always be enough and greatly limits how much water you can use.

This is where RV water filters come in, but selecting the best RV water filter is a big decision. These reverse osmosis units will filter any unsafe water you find on your expeditions and give you instant fresh water that’s ready to drink. Moreover, they get rid of harmful bacteria, heavy sediment, and metals to give you a fresh water supply that rivals bottled water. If you are planning on getting a reliable and efficient inline filter, here are five of the best RV water filter systems available today.

Furthermore, it enhances the water’s taste by removing the chlorine taste and any bad odors. What’s more, you get to enjoy all these benefits at almost no cost since it’s a highly affordable unit. 


The Camco TastePure filter uses a carbon filter that is designed to serve you for weeks or even months of camping. It has a large filtration capacity that lasts for about three months while maintaining excellent filtration capabilities and preserving your water taste.

RVGUARD Inline Water Filter

If you’ve been searching for the best RV water filter systems that can filter enough gallons of water to fill your RV fresh water tank with clean water, then RVGUARD has got you covered. This filter has an impressive water flow rate of 0.5 GPM and can filter up to 15,000 gallons of water. So, whether you need to filter tap water or water from other untreated water sources, you can be sure this filter will meet all your purification needs. 


Since its inception, RVGUARD has strived to deliver high-quality RV products and accessories. As frontiers in the industry, they perfected the RV water filtration systems of their purifiers to ensure they can handle unsafe water from any water source. These reverse osmosis units use four filtration methods to clear any unsafe water of heavy sediment and debris, chemicals, and heavy metals.

In these stages of filtration, water goes through a metal filter in the first step. Here, the sediment filter removes silt, stones, heavy metals, and other compounds such as arsenic and fluoride. Next, the KDF55 filter further entraps any remains of heavy metals, hydrogen sulfide, and chlorine. 

The activated carbon uses carbon filtration to get rid of unpleasant odors and any traces of chlorine taste in the water. Finally, the sponge in the last part only lets clear, healthy drinking water through. 

When using this filter for the first time, you will notice carbon being washed out. Let the water run until the extra carbon clears out of the system. 

Once you start using this filter, make sure you replace the filter cartridges after three months or after filtering about 15,000 gallons. This helps ensure the filter continues purifying dirty water at optimal efficiency and producing clean, tasty water. 

The RVGUARD filters can be used in a wide variety of tasks, including camping, gardening, farming, and marine activities, among others. 

These filters for RVs can operate under 34-110F and should be exposed to a maximum water pressure of 60 psi. Exerting higher levels of water pressure can damage them.

You’ll be happy to know that this filter is tried and tested by independent parties to ensure that it meets high-quality standards. 

This premium filter includes a multi-stage filtration process where the first layer mainly removes sand and other large particles. The Kinetic Degradation Fluxion or KDF layer stops any rust and chlorine particles. It also clears any elements that make the water cloudy. 

Next, you have an advanced filtration layer that mainly filters out fluoride, which stains and degrades teeth. It is also here where heavy metals like lead are removed. Eventually, the purified water undergoes bad taste and odor filtration in the granulated carbon layer. The final result is clear, tasty water that is ready to drink. 

This versatile RV filter can be used for more than just camping activities. For starters, you can use it as a filter for your kitchen under the sink filtration system.
