What Is An RV Water Filter


An RV water filter is one of the essentials for your recreational vehicle, camper, trailer or any vehicle that has a water hookup. The best ones can be used for applications and purposes, including gardening, cleaning the car and filling up water tubs. But at the very least, one is used in a recreational vehicle’s water system. It has the main function of getting rid of chlorine taste and odor, sediments, volatile compounds, heavy metals and other impurities.

It works by filtering the water that gets into your water system tank. Most of these can be attached or connected to a hose. They also come with a hose protector to prevent the straining in your faucet or spigot.

Some are inline units. They combine sediment removal and carbon filtration – few of the best features to look for when buying an RV filter. The best ones also include accessories, including an RV water filter stand.

Many of these also come with technologies including a KDF, which works by improving water taste and odor. It can also prevent bacteria from building up or collecting in the system when it is not in use. Most also have high flow rate, commonly 2.5 GPM and can handle up to 125PSI.

Some are smaller in size, suiting families who do not use their RVs often. But for those who use their recreational vehicles in the entire camping season or looking for a more heavy-duty product, they can opt for canister systems.

How Does It Work


Filtration systems are recommended for every RV owner because they can filter water wherever we’re parked or camping aboard our vehicle. As you know, pure and clean water is essential for our health. For this reason, we have to use a water filter that will help us filter water during our trip. Many of them also work to eliminate any bad smell and odor of water. They can also function to remove contaminants, including sediments from the water.

Types Of RV Water Filters


When looking for the best water filter for RV hose, you should first know the types of filtration kits and systems available on the market. What are the different types to which you need to get yourself familiar? By knowing the following types, you can have a better guide when trying to choose one.

Sediment water filter

It is one of the most basic types that work like a traditional strainer. This type can catch particles found in the water. It is chosen by those who want to protect their faucets, toilet valves, water heater and water pump.

But then, this type of water filter will require more maintenance than other types of water filtration systems on the market do. The sediment filter can be a good choice if you’re trying to filter water going into your recreational vehicle.

Activated carbon water filter

Just like the sediment water filter, the carbon water filter is another good choice for part time or full time RVers, but it does more than sediment filtration. It also works by improving the overall taste and odor of water getting into your tank.

That is why it is a cooler choice if you also want to get rid of that foul odor and bad taste in city water commonly used in RV camping grounds.

Most types available now can filter water and improve the overall quality. They can also get rid of volatile organic compounds, mercury, asbestos and lead, among other heavy metals to find in water. For this type, you have three options.

  • Solid block carbon
  • Modified carbon block
  • Granular activated carbon

In general, more people prefer the GAC, as it is the most cost-effective types yet is also one of the most effective in getting rid of contaminants.

Ceramic water filters

Aside from the sediment and carbon filters, there are also the ceramic water filters. At the very least, they have holes, the ones filtering out the contaminants, including bacteria, protozoa and sediments.

On the downside, they seem to be ineffective when removing the chemical contaminants, including chlorine, lead, mercury and other chemicals.

The good thing is that many of the newer types have combined carbon materials to remove the chemicals in the water. So if you’re buying a ceramic filter, you should choose one that has carbon filter component and made for recreational vehicles.

Why Do You Need An RV Water Filter


Maybe you’re asking, why you need a recreational vehicle water filter. There are many benefits of having one for your RV. As you may know, heavy metals, sediments and other particles can damage your RV’s water system. For better explanation, check out the following for the benefits of having a good RV water filtration system or kit.

Sediment removal

It causes cloudy, turbid and dirty water, leading to inconvenience of your loved ones. But it is more than an inconvenience because sediments can also harm your equipment, which might need replacement sooner.

Chlorine odor and taste reduction

Most campgrounds provide water supply, but it is mostly chlorinated. Chlorine is needed for treatment all the pollution and contaminants in the water.

But with its high content, other heavy metals, such as lead, can leach into the water especially if it gets in contact with old alloy pipes. That’s not all though. Chlorine also makes unpleasant odor and taste in water.

By using a good water filtration system, you can reduce its level in the city potable water available in the camping ground. Remove the chlorine smell and taste from the water going into your RV using one of our top recommendations above.

Bacteria reduction

One of the most proven benefits of having a high technology water filtration system is its ability of destroying harmful organisms. Some of these include fecal coliform, parasites and campylobacter jejuni. Exposure to harmful bacteria can lead to digestive problems, including stomach discomfort and diarrhea. That is why it is essential to use a powerful water filtration kit for your RV.

Hair, skin and nail health

Having an RV water filter kit or system, you can also improve your and your loved ones’ skin, nail and hair health, as it can get rid of unwanted minerals and harmful contaminants that would otherwise cause skin, hair and nail issues.

Factors To Consider Before Buying An RV Water Filter


Check out the following for the most important things to consider when buying a recreational vehicle filtration system or kit.

Amount of water to filter

How much water to filter? Do you only want to filter drinking water? Or do you want to purify all the water getting into your RV water system? Thinking about it, you can choose the filter with the right capacity to work based on your specific needs.


Just like when buying anything online or in store, you should determine how much you’re willing to spend on the RV filtration system. Doing so, you can save so much time because you will be able to narrow down your options based on the budget you have set for the new investment.

Micron ratings

These water filters are rated with a micron rating, referring to how small the particles that the kit or system will let pass. The more pollutants and contaminants will be filtered out by those with a smaller submicron or micron rating.

Ease of installation and use

Do not go for those with complicated set up processes. Instead, look for one that you can install easily and coming with a detailed instruction on how to do it. You must also choose one that won’t give you a hard time to replace the filter when the time comes.


What filter size do you need? When deciding for this one, you should also look into your water pressure. The more powerful is the flow of water of a bigger filter. That is one thing to note when searching for the right filtration system for your RV.

Nevertheless, you should choose a filter size that will accommodate your filtering needs especially if you have to purify all the water getting into your RV.


When looking for one for your RV, you should consider the type of product you’re getting. Start from the list of types we have highlighted in this guide.

If you need a basic filtration of sediments and particles, choose the sediment filter or an inline filter. You might also get a canister type that you can customize based on your requirements.


When buying a new water filter, make sure that you’re getting one from a reputable and trusted brand. See to it that it is committed to quality and durability of their products.

Most of them also offer highly precise filtering systems with both carbon filter and KDF technology.
