When you’re traveling and living in an RV, having a fresh water supply onboard is a real gift. But how long does an RV water filter last?
Ensuring that you have plenty of clean potable water that’s safe to drink is important. Safe water for drinking, showering, cooking, and washing dishes requires a water filter that removes sediments and also removes contaminants. An inline water filter (or any type of water filter) is easy to obtain. Today we’re looking into RV water filters and how long they tend to supply clean drinking water to your RV.
What Is an RV Water Filter?
A water filter cleans the water from your fresh water tank or city water source. The object is to give you safe drinking water and better-tasting water as well. As water flows through the filter, sediment and contaminants are removed before they reach your faucet.
Our post on the simple truth about how RV water filters work offers far more information on water filters in general. But today we’re especially interested in how long an RV water filter lasts.
How Often Should I Change My RV Water Filter?
We all want to know that our water filter is doing its job. Knowing when to change it is key. Unfortunately, there’s no set answer to the question of how often to change a water filter. There are a number of factors that come into play.
First, of course, is how often you use the filter. How much do you use your RV? Are you using a whole-house filter or are you only filtering water at your kitchen sink? Is one person using the water in the RV or are there five RVers onboard? How much do you dry camp? (Us boondockers tend to be very sparing with water use, so we run a lower total volume of it through our filters.)
One of the most important factors that determine the lifespan of your water filter is the quality of the water flowing through it. If you’re traveling around connecting to water sources at a wide variety of campgrounds, water quality can vary considerably.
When poor quality water flows through a filter, there are likely more contaminants to filter out. The more sediment and contaminants a filter removes, the more frequently you’ll have to change the filter. On the other hand, high-quality water will present fewer contaminants for the filter to trap, so it will last longer.
So, the answer to how long an RV water filter lasts or how often you should change your water filter really depends on how, and how much, it’s being used. But certainly, if you notice the flow rate slowing, that’s a good indication that a new filter is well past due! Or if you’re an occasional RVer, hitting the road on summer weekends to get away for some R&R, a good-quality water filter will likely last you for the whole season.
Can You Clean an RV Water Filter?
Some types of water filters can be cleaned but certainly not all. For example, some ceramic filters are capable of being scrubbed and cleaned with a brush or scouring pad. With this system, however, a carbon block is usually added for additional filtration and purification. The ceramic part can be cleaned, but the carbon block filter would simply be replaced.
- Connects easily to your standard faucet via a diverter valve with no tools, and requires no electricity or permanent modifications to your plumbing.
- Removes more than 99.7% turbidity, but leaves beneficial minerals in the water for good health and excellent flavor.
On the other hand, a solid carbon block filter is not a filter you would clean. When a carbon block filter has done all the filtering it can, it’s time to replace it.

The same is true of the typical inline water filters used by many RVers. Once these stop filtering well, they’re simply discarded and replaced. Both this filter and the previous one are generally placed inline in your city water hose, between the city water source and the RV.

Sediment filters work like a sieve to remove particles. While some sediment filters can be cleaned, in our humble opinion the cost of replacing them with new ones is worth the peace of mind that comes with a brand new filter. Sediment filters also don’t improve the taste or smell of poor-quality water. Instead, they’re designed to remove sediments such as sand, dirt, silt, and rust particles to keep them from affecting components of your RV’s water system, like the water pump.
A popular type of water filter that uses activated carbon is the gravity-fed Berkey filter which sits right on your countertop. You simply add water to the Berkey and its activated carbon filter purifies the water before you drink it. With this unit, the activated carbon filters can be cleaned, dried, and reused, but once clogged with sediment or particles they need to be replaced.
This “Travel Berkey” comes with two purification elements. Together they’re capable of filtering up to 6,000 gallons of water.

Is an RV Water Filter Worth It?
Absolutely! We certainly wouldn’t be without ours.
Remember, when you travel and obtain water from various sources, you can never be sure of the water quality. There’s a good reason why most RVers prefer to have some type of water filter onboard, especially if they intend to drink the water, as opposed to just washing with it.
Some campgrounds have water sources with very old plumbing. And when you fill your fresh water tank from a spigot at a state park, city park, gas station, or any other unknown source, you really have no idea what the quality of the water is.
So, yes…an RV water filter is absolutely worth having. Even if you don’t RV frequently, or drink the water, a simple inline filter should work nicely to remove sediment and help protect components of your RV’s plumbing system. And they won’t break the bank.
What Is the Best RV Water Filter?
Here again, the answer to this question really depends on how use your RV. If you camp for a few weekends and maybe a week or two in the summer, the small inline water filters (like the Clear2O or Camco TastePure above) are likely all that you need.
But what if you RV more often… and want to drink the water on your RV? (Plus help save storage space, money, and the planet by reducing the waste of single-use plastics?) Our favorite way to assure that our water is safe to drink is, by far, our Acuva UV-LED water purification system. Not only does it eliminate bacteria and viruses, but the advanced pre-filter also removes lead, heavy metals, chlorine, mercury, and other contaminants.
Our Acuva system is compact and easy for any modestly-competent DIY RVer to install. The 2-liter-per-minute flow rate is plenty for filling drinking water glasses and bottles. And since it’s only needed for drinking water, that’s perfect.
At first glance, the Acuva system may appear to be on the pricey side, but the initial cost is easily offset by the fact that it’s designed to purify 120,000 liters of water throughout the lifespan of the system. That’s an awful lot of bottled water to buy, haul, and store (not to mention the immense amount of plastic saved).
We’ve lived in an RV full-time for nearly 20 years, and take our water safety seriously. So we looked very seriously into the filtration capacity of the Acuva system to make sure we were getting the level of purity we want from our water. We even made a video about it, which you can watch here:
We also have a video of the Acuva installation process, which is an easy DIY project. See the process laid out step-by-step here:
