10 Best RV Water Filter System Reviews – Buying Guide For 2021

If you don’t have a water filtration system in your recreational vehicle (RV), you’re risking more than just your health.

It’s a well-known fact that the campground water you use in your RV, whether from the city or well, is filled with impurities and sediments.Failing to pass your water through a filtration system can easily make you sick and spend a lot of cash getting your good health back.

Even worse, letting unfiltered water flow through your RV water systems- including faucets, toilets, water heater, water pump, etc. - can seriously damage them and make you spend a huge sum of money to repair and replace them.

That being said, I’ve prepared the guide below to teach you how to find the best RV water filter for your RV.

We’ll also discuss the 10 most popular RV water filters used by RVers all over.

Let’s dive into the details right away.

What’s an RV Water Filter?

A water filter for RV refers to a water filtration system that you install in your recreational vehicle to purify water.

Most RV owners will agree with me that they either use well water or the chlorinated city water in their RVs. The city water has always been associated with unpleasant smell and taste which the filtration system removes to make the water suitable for drinking and cooking.

The system also does a great job of filtering out the minerals such as magnesium, calcium, and potassium and other sediments found in well water. If not removed, these minerals can not only affect your skin health but also damages your RV water systems.

With the evolution of water filtration technology, you’ll find various types of water filtration systems on the market today—with different working mechanisms, features, etc.

The best RV water filter should be directly dependent on your specific water needs (I’ll show you how to pick the right unit for you later in this post).

In our next section, we’ll take a closer look at the top-rated water filters enjoying wild usage among all the RVers.

Entire Camping Season RV Water Filter - A Buying Guide

I wish I could tell you that getting the right RV water filter system for you is as simple as waking up one day, walking to a store and picking a unit that grabs your attention.

The process involved in buying a water filtration system for RV isn’t that easy.

Most people don’t seem to know this, and they end up choosing the wrong units that don’t work as they expected.

Below, I’ll outline for you some key features and aspects that will help you pick a unit that an will see you through the entire camping period:

Type of RV Water Filter


The number one thing you should look for when buying a water filter for your RV is the type of water filter.

There are different types of filter systems with different water filtration capabilities, designs, and features.

The right type for you should directly depend on your specific water filtration needs.

If you plan to filter water for the entire RV (which I advise you to do), then the best types of RV water filters for you include:

  • Inline filter: they’re attached to the point of water entry into your RV and help filter out the sediment, and bad odor and taste found in water.
  • Compact canister: this model is similar to the whole unit used for homes, only that it has a compact design to fit in an RV. You can also easily customize it to suit your needs.
  • Reverse osmosis (RO): RO is also a good option for purifying water. However, I don’t recommend it as the main option for your RV as it also removes minerals in your water, stripping it off its health benefits.

Ease of Installation

Make sure you chose a model that is extremely easy to install.

I urge you to look for a filter system that does not require any assembly and installs easily and quickly. Keeping in mind that you’ll need to replace it after around 3-4 months, you should also ensure the replacement process is equally easy and straightforward.


How suitable the filter system is for serving its intended purpose is another crucial factor you should keep in mind.

Of, course, you should ensure the product you buy actually filters out all the hazardous elements found in the campsite water. Ensure it can remove the bad taste and odor associated with chlorine in the water.

A good way to ensure that you’re buying a functional product is looking at NFS International certification.

Looking at what the previous users of a unit have to say about it will also help you ensure you’re buying a truly functional product that meets your needs and requirements.


Buying an RV water filter designed by a reputable brand is also a good way of ensuring you end up with a unit that meets all your water filtration needs.

Some of the companies that have made a name for themselves in the water filtration industry include Camco, Culligan, Aquasana, WaterSentinel, to name but a few.

An added benefit of buying from the top companies is that most of them back their products with a long enough warranty so that you can always contact them in case your product develops any functionality problems.


Finally, you should check how much the water filter you’re planning to buy will cost you.

As you have noted from the 10 units we’ve discussed above, the price fluctuates from model to model, depending on the manufacturer, filtration technology, features, and so on.

If you want to get a model with all the bells and whistles, you should be ready to cough out more money.

And if you’re on a tight budget, you should look for a basic model that does the intended job well.

Frequently Asked Questions

1. For how long will my RV water filter last?

Most of the filters at the market today last for around 3 to 12 month. The longevity of the filter usually depends on the product quality as well as the manufacturer.

With that it in mind, I don’t recommend you to wait until the recommended period is over to change your filter. In most cases, you should replace it in 3-6 months.

Also, you should keep checking the filtered water to see if the unit is doing its job or needs replacement.

2. How do I install an RV water filtration system?

Installing a water filter in your recreational vehicle (RV) is an easy task that you can carry out on your own, without necessarily hiring plumbers to do it.

Check the following video on how to install an RV water filtration system:

3. Can I use the unit to filter hot water?

NO. The manufacturers do not recommend running hot water through their units. From their point of view, the unit is only designed to filter cold water, and it might not adequately filter hot water.

Besides, hot can easily reverse the process of chemicals absorption, causing contaminants to be released back to your water.

In case you accidentally run hot water through your RV water filter, you can simply run cold water through it for around 1-2 minutes to help flush out the hot water.

Final Verdict

If you own and regularly use a recreational vehicle, then you should consider installing the best RV water filter into it.

The unit will remove harmful contaminants in water to make it clean and safe for drinking for your family or the RV occupants. Filtering water used in your RV will also help protect the water systems from getting damaged beyond repair.

In the above post, I’ve taken you through the 10 most popular water filters used by other RVers across the states. All these models have great functionality and are quite reliable when it comes to filtering RV water.

What’s more, they come with affordable price tags, so getting one for your RV will not cost you an arm and a leg.

  1. We purchased Camco EVO filter to replace the one inside our 2013 sandpiper camper. The one they had was expensive to replace the filters. So I was looking for other options. It took a run to the hardware store to find the right fitting to connect to our already existing plumbing. But after installing we have had no issues. We installed last night (11-27-17) and I am very happy with it. Real enemy filters are so affordable do this one and easy to find! Highly recommend if you are wanting to save money. Came with everything you need if you are just putting it in for camp site hook ups. But we wanted it more permanent inside. Would buy again. And will update if we have any issues !!
