Best RV Water Filters of 2023

What Is an RV Water Filter?

The easiest way to describe a water filter is that it is a device that works to ensure there are no microorganisms in your water once it reaches your faucet. It also works to remove the strong odor that microorganisms carry when they are in the tank.

In other words, it is a filtration system that gets rid of contaminants and eliminates sediment from water that you pump into your RV. It also improves the taste of the water by removing deposits and reducing chlorine. By eliminating microorganisms, water filters help prevent your appliances from clogging and damaging.

A water filter is also an affordable, eco-friendly alternative to purchasing bottled water. It gets rid of any lead in the water from old and corroded pipelines. You can also get an ultraviolet system, which helps to make untreated water sources potable. 

Getting an RV water filter is essential to drink clean, fresh water that tastes good. Not only do you need water filters, but they must also be changed regularly and before their effectiveness fades. 

Also, make sure that you have the right filtration system for what you need to use water. Preferably, you want to install a filtration system that will provide you full capacity for your family so that everyone can shower, drink, and clean.

Types of RV Water Filtration Systems

There are a few things to consider when selecting the type of filtration system for your RV. Essential factors to consider are the frequency of use, desired level of water, and the contaminants you’ve got in your tank. Based on this information, you can decide which type of RV water filter is best or which combination of filters can provide your RV with stellar filtration performance.

Carbon Filters

This system is very common in many RVs. One of the biggest reasons why is that it improves the taste and odor of the water. Through absorption, carbon filters remove chlorine chloramines and eliminate herbicides and volatile organic compounds. 

While carbon filters work to improve the smell and taste of your water, you need to make sure that your water source does not have heavy sediment or pathogenic bacteria so that you can get the best results from carbon filters.

Sediment Filters

If you want an extra layer of protection, you will find sediment filters to be a delight. These filters work extra hard to remove dirt and debris from your RV’s water. Sediment filters also make your other filters more durable by protecting them as well as your plumbing. 

Sediment filters complement carbon ones, which need to be changed frequently. Also, sediment filters help UV purification as dirt particles would prevent UV light from disinfecting the water. Unless you can always connect to municipality water sources, having sediment filters is essential.

If you do not install these filters and have sediments in your RV, you may notice your water is dirty and has an unpleasant taste. Besides causing damage to your health, sediments can also cause damage to your shower and faucets by clogging pipelines and reducing water pressure. 

Ultraviolet Purification

If you suspect that your RV contains bacteria or viruses, then ultraviolet purification will be the best option for you. It exposes bacteria to disinfecting ultraviolet wavelengths. 

UV lamps prevent bacteria from reproducing by using radiation, ensuring that it does not get into your drinking water. A UV system works well if you travel with your RV to places where the water quality is questionable. The great thing about a UV purification system is that you can purify water even if you have not used it in a while. 

Remember that ultraviolet purification does not improve the water’s taste—its primary purpose is to sterilize the water. If you want to sterilize the water and improve its taste, you will have to combine another filtration system with ultraviolet purification, such as carbon filters. 

Reverse Osmosis Systems

For RV enthusiasts looking to find a comprehensive filtration system that will handle just about everything, opt for a reverse osmosis system. Besides being a very powerful form of filtration, reverse osmosis systems deliver high purity water and eliminate dissolved solids.

This system makes water go through a semi-porous material that strips dissolved salts out of the water. The sediment pre-filter removes the water’s debris and improves its taste after it has gone through the entire process. 

While this system is highly effective, but it is not very practical for most RVs. It takes up a lot of space because it needs a dedicated storage tank and a booster pump. 

It also needs a permeate pump to lessen waste, but many campgrounds do not provide this, so it is tricky to complete the entire filtration process. If you do not use a permeate pump, then the water that the RO unit processes could become brine, a term used to describe water containing rejected contaminants.

If you can manage to have your water complete the entire process, you will reap the benefits of a reverse osmosis system and will get clean water that tastes good.

If you’re looking for campgrounds that provide all the amenities you seek, including a permeate pump, here are some of the best places to travel.

How to Choose an RV Water Filter

There is an array of options when it comes to choosing a water filter. It is an essential part to get before you head out on a trip because you and your family will have to use water. Since you will need a camper water filter, how do you know which one to get?

You should consider a few factors to help you get the right water filter to meet your needs, including knowing what’s in the water you’re drinking, how much filtered water you need, how often you’ll use the filter, and how much it will cost over time.

1. Know What’s in the Water You’re Drinking

There are numerous contaminants in your RV tank. You need to know which ones are present and how to filter them. The easiest way to find out what contaminants are in your tank is by performing a water test. Keep in mind that performing water tests can be challenging when moving from one campsite to another. 

Most RV campgrounds supply city water in their parks, and its supply source has used chlorine to disinfect the water and rid it of waterborne diseases. Something else to keep in mind with chlorine is that it does not have a pleasant odor and can make water taste less appealing.

The other water supply source at parks is wells, which contain heavy metals, sediments, and microorganisms. Whenever you are located somewhere with hard water, know that your tank could collect magnesium and calcium, resulting in damaged plumbing.

Not only can you put your health at risk if you do not know what is in the water that you are drinking, but you may suffer unnecessary repair or replacement costs. 

2. Decide How Much Water You Need to Filter

An important aspect that you need to consider is how much water you want to filter. This key factor is going to determine which filter you buy. If you have your whole family with you in the RV, it will require you to use a lot of water. That means you’re going to have to buy a multi-canister system or an inline filter.

You also have the option to purchase a filter that is specifically designed to handle the water supply for drinking and cooking. In that case, it’s best to opt for a countertop filter or an under-sink filtration system. The issue with these options is that they will not remove contaminants from entering your appliances, but they will supply water that you can drink. 

If you want to incorporate systems to clean the water, that is also possible with a whole-RV system and an under-sink system.

3. Consider How Often You’ll Use the Filter

Your choice of a water filter will also depend on the type of excursions you take. Is RVing a hobby you do once in a while or are you an enthusiast who covers extensive mileage on various terrains and sea levels? If you are serious about RVing, then you might want to look at a comprehensive filtration system. 

You will not need a complex water filtering system if you use your RV only on certain occasions. Remember that you will need a system that can neutralize bacteria if your water source is a dam or a lake. At the very least, you should have carbon and sediment filters.

You cannot rely only on your RV’s past use, as you must determine how much you will use it in the future.  It’s best to estimate your RV usage and then add a bit extra so that you don’t end up buying a filter that is not sufficient.

4. Calculate the Cost Over Time

By taking into account all of the above factors, you can determine how often you will have to change water filters. The different filtration systems vary in price, and installing multiple systems over time can become quite pricey. That means your budget will play a significant role in your purchase.

When comparing which system to choose, know that you need to install replacement lamps annually in a UV system. Also, the absorption capacity on a carbon filter diminishes after processing a specific amount of water.

Conclusion

There are various inline water filters for RVs on the market, and we have included several types that you can choose from based on your family’s needs. Selecting the right one for your RV comes down to several factors such as your budget, how clean you want the water to be, and what contaminants you want the filter to clean.

The ones we have specified are a good combination of all the factors. Some of the water filters have more features than others, which is also reflected in their price. The great thing about choosing an RV water filter is that owners can select what parts of the RV to target. 

If you want only clean water for drinking and cooking, then you can do so. Otherwise, combining two filtration systems will provide the entire family with full water capacity for all uses. 

The advice on which water filter to purchase is not a one-size-fits-all approach. It depends on what it is that you need and how much you can afford. We here at the Wandering RV would love to know which water filter system you plan on buying and why, or which system you currently use and how you like it. Feel free to leave us a comment below.
