What to Look for When Buying an RV Water Filter

To figure out which among the products introduced to you is the best RV water filter based on your unique needs, it’s advisable to make your choice taking into consideration these crucial factors:

Type – One factor you have to consider when searching for the ideal RV water filter for your needs is its different types. One of your options is actually the in-line filter, which you can use at your RV’s entry point. It’s a good choice if you’re planning to do basic sediment filtration and get rid of bad odor and taste in water.

You may also choose the compact canister. Similar to the one, which is mainly used for a whole house system, this filter still has its own distinction in the sense that it is more compact. This results in the filter fitting in your RV. You can also customize it based on your specific needs.

Another type that you can choose is the reverse osmosis. It’s a good choice if you want to purify water. Other options that you have are the sediment and carbon filters.

How much water you plan to filter – It’s also advisable to make a decision based on the amount of water you plan to filter. In this case, ask yourself first whether you want to filter all water or just some of your sources of water. That way, you can decide on the specific type of filter that works for you.

In case you are exposed to dirty water with sediment, then you may want to invest in an RV water filter capable of filtering all water in your RV. In this case, you can go for sediment filters that are known to be common in RVs.

Ease of use/installation – Make it a point to choose a filter, which is never that hard to use or install. Remember that you will be replacing it after some time – after around 3-12 months. Make sure that you won’t deal with a lot of hassle once it’s time to change the filter.

Frequently Asked Questions (FAQs)

How long does an RV water filter last? How often should I change it?

RV water filters last for around 3-12 months depending on the brand and the quality of the product. That said, it’s advisable to replace it every 3 to 6 months. As mentioned, there are also certain models that can last for up to 12 months. Such products should be changed at around 9-12 months.

Make it a point to observe the output after the filtering process, too as this will also give you an indication whether it’s already time to change it. In most cases, changing or replacing the RV water filter is already necessary if the water flow tends to slow down or if the color of the water gets darker.

Can I use it for hot water?

The answer is no. It is because hot water can’t be filtered adequately when you run it in the RV water filter. In fact, it might reverse the process of absorbing chemicals, causing the release of contaminants back to the water. That said, only use the filter on cool or cold water.

In case of accidentally running hot water through your chosen filter, you can fix that by running cold water to it for around two minutes. That would be enough time to flush the hot water out.

Does it leak?

Yes, the RV water filter might also leak, especially if you have already been using it for quite a while. If you notice leaks, then it would be best to remove the water filter first. Check it thoroughly for damages or cracks. If there are indeed damages or cracks then you may need to change or replace it with a new one.

Another possible reason for the leak is the incorrect installation of O-rings. Examine the O-rings and ensure that they are still in the right places. In case of missing or damaged O-rings, a replacement of the filter may also be necessary.

How to install an RV inline water filter?

To install your chosen RV water filter, you have to install the rubber hose seals on the canister’s two sides first as well as the shut-off valve of the garden hose. Use plumber’s tape to wrap all fittings. You should then let the canisters line up using the correct flow pattern.

After that, install the PVC pipe fittings as well as the hose adapters on the two sides of the canister. The next thing that you have to install is the canister O-ring. You should also set the white filter cartridge next into your canister. Tighten it to its head. Do the same for the carbon filter then shut off your RV’s water supply.

The next step is connecting the water line from the source of water to the canister’s head. Connect a 3-feet water hose approved for RV hose to the head then next to the inlet. Turn on the water supply in your RV. This is the time when you should check for leaks so you can tighten the fittings again if necessary.

After that, decide on where you plan to mount the filter. Once you have made the decision, you can mount it using the provided brackets.

Where is it made?

An RV filter is usually made of a kind of filter media, which works in mechanically trapping pollutants. In most cases, this filter media comes in the form of an ultrafine sieve or web, which acts similarly to a tea strainer when it comes to trapping unwanted particles in the water.

Other water filters are constructed based on the process known as absorption. It works by retaining the contaminants in a medium or adhesion’s microscopic pores where they are attracted just like a magnet to the media’s molecules.


Finding the best RV water filter is a must, especially if you plan to travel on the road frequently. With the aid of this filter, you have an assurance that you will always have an access to safe and clean water.

10 thoughts on “Choosing the Best RV Water Filter 2019”

  1. I have used the blue Camco 100 micron filter.
    It no way compares to the green Clear2o 1 micron RV filter for removing odors and taste for drinking water. I believe you should rerun yours tests.

  2. The Clear2O RV Inline Water Filter surpasses performance on all the filters mention on this article. It filters water at the one micron level. It uses a solid carbon block instead of granular carbon. Big difference. The ones mentioned above filter at the 100 micron. This is a big difference.

  3. Thank you for your reviews. Please add GPM when reviewing them next time. Some filters may work well (or not), but you need to compare micron filtration and GPM to figure out if that filter will work for you. I used to love the Hydro Life filters. Now they are not worth their price.

  4. Most of our travels are areas where the water is very “hard”. I am as much concerned about filtering the water to maximize the life of our water heater and plumbing fixtures. Which filter does the best job in doing that?

    • I highly recommend you to try Camco 40043 TastePURE Water Filter (best of the best) & Beech Lane External RV Dual Water Filter System (new release)
