10 Best RV & Caravan Water Filter in 2021

Travelling is one of the biggest adventures one can step foot out for, but some things can really take that charm away from you, and one of them is not having access to clean water.

When settling out in an RV, you do not need just drinking water; you also need it for showering, cleaning, plumbing, and other purposes.

Inadequate water quality is just going to ruin all of that for you.

This is why we have compiled a list of the ten best RV water filters in this article. We also discuss which one would be the best for you and why you should pick it.

So let’s jump right in.

Our Top Pick

4.7/5

Travel Berkey

This Berkey filter comes equipped with a purification system for the water, which makes it your perfect travel buddy. The 1.5 gallon-capacity water filter is perfect for all travelers.

Types of RV Water Filters

As we discussed before, you can get your hands on different types of water filters. Each one has a specific technology of its own, and you need to be aware of their differences before deciding which one you should buy.

Sediment filters

A sediment filter is mainly responsible for removing dirt and debris from your drinking water. They also increase the filter lifespan of the other filters present.

Sediment can affect the odor and taste of the water. It can clog your pipes and other water appliances. They also reduce the water pressure and efficacy of your other water systems.

Thus, this filtration method would be necessary to keep such sediment issues from happening in your RV.

Reverse osmosis systems

A reverse osmosis system is a compelling filtration process. Water is made to pass through a semipermeable membrane during the filtration process that removes all dissolved solids and salts from the water.

Usually, reverse osmosis systems are not really feasible for an RV. This is because the reverse osmosis system requires its own storage tank as well as a booster pump.

It pumps a great deal of wastewater called brine, which can become hard to deal with in campsites.

But then again, with some effort and thought, you might be able to make a reverse osmosis system work for your RV.

And if you do, you’ll be in luck because reverse osmosis is one of the best ways to filter water.

Carbon filters

The carbon filter is the most popular for restoring a good taste to water. In city water, chlorine is added to it destroy harmful bacteria, but it leaves a sharp taste and smell. Carbon filters then manage this.

Carbon filtration also eliminates other elements like pesticides, herbicides, VOCs, etc.

Ultraviolet purification

These water filters work by neutralizing the bacteria present in your water through exposure to UV light. Thus, they cannot infect your water anymore.

It does not improve the taste of the water, however, and you will have to pair it with another water filter for the most optimal results.

Installing an RV water filter

You first need to decide whether you want a carbon block purification method, sediment filters, UV light purification method, or a reverse osmosis system.

This will depend on your need and the quality of the water that you need to filter, and whether it is city water or not.

The next step is to install this water filter. An inline filter or canister RV water filter will either be placed externally outside your RV or below the sink.

A filter/pitcher combination will be a countertop filtration system.

Figuring out the correct configuration is necessary to ensure you have the right product according to your needs.

Hence, you need to check your water supply and carefully determine which of these water filters will work the best for you.

What Is an RV Water Filter?

An RV water filter is a convenient device that you can hook up within your RV (or elsewhere) and find clean drinking water from it (or even water for other purposes).

It basically filters out the impurities and contaminations from the water supply through either a chemical/biological process or a physical barrier.

These filtration systems can remove as little or as much of the impurities and contaminant particles found in your water. They also work on the odor and taste of the water.

These RV water filters have various technologies that they can use. Often they come with an activated carbon filter that often uses the ion exchange process for water filtration.

There are also other kinds of these water filters, such as an RV inline water filter or a canister RV water filter.

All of them have a multitude of techniques and processes that work in different ways but are adequate for water filtration.

In short, for those who travel around a lot and would like cleaner, usable, and drinking water on the go, RV water filters are a great product to invest in.

How Does a Water Filter for RV Work?

RV water filters ensure that you always have clean drinking water on the go. They have different methods and different types of filters that remove impurities from the water we utilize.

Usually, the dirt from the water can be removed using any one of the two upcoming mentioned methods:

The first method is simple physical filtration. A filter is used to strain the water to filter out impurities from it. It could be any kind of a thin filter that does not let these impure particles pass and thus, filters them out.

The second method is a more complex chemical filtration. This works a little differently than physical filtration. All of the water passes through a chemical substance that withholds the impurities present inside it.

If you want to filter all of the water from the storage tank of your RV, it is preferable that you find a water filter that connects with a hose.

An inline water filter would be a great choice in this situation. It combines a sediment filter with a carbon filter because they usually work best for situations like this.

You can easily find them in a small size. But if you’re looking for something that has a longer shelf life or a better flow, then canister filters are the way to go for you.

How to Pick a Water Filter for Caravan?

Even after knowing all the different types of water filters, you can choose from and their specifications, you still might be confused about which one you should pick.

That is entirely okay because due to the multitude of factors involved in the process, it can become a little confusing to decide which filter would be perfect for your needs.

This section discusses certain factors that you can evaluate to help yourself make this decision and pick the best RV water filter for yourself.

Understanding the types

After we have taken a detailed look at the different types of water filters we have available in the market; you first need to sit down and see if any of them directly suits your need.

Inline filters are perfect for removing bad smells and tastes from your water. An inline water filter will also be great at sediment filtration.

The reverse osmosis system is good for you if you’re looking for a purification system.

Similarly, all other forms of water filters have their own set of uses, understanding which is crucial in helping you make a decision.

If you are unsure about which water filter does what, you might end up buying something that does not match your needs at all.

It will be a waste of money and also incredibly frustrating to see your water filter not working in the way you would like it to work.

Understanding your water supply composition

First, you need to know what sort of contaminants and harmful materials are present in your water and how you can remove them.

The easiest way to do this is by performing a water test, it can be a little complicated sometimes, but it does give you an appropriate answer.

There are other ways to determine this as well. A lot of campsites are supplied with city water, which has chlorine present in it as a disinfectant. This chlorine gives an unpleasant odor as well as taste to the water.

If your water supply comes from a well, then that contains a lot of other microorganisms and heavy metals, which are dangerous in their own way.

Until you know what is contaminating your water, you will not be able to fix the problem without most likely messing something else up.

Understanding your water consumption

Decide how much water you will utilize and for what purposes. If you’re going camping with your whole family, you’ll probably need inline filters or multi-canister filters, which have the capacity to provide filtered water to more people.

There are also specific filtering systems that just focus on supplying water you can use for cooking and drinking, but they will not keep any harmful materials away from your appliances.

Understanding the frequency of your water usage

Sit down and evaluate how much you are going to use your RV in the months to come.

If you plan on taking frequent trips, invest in a complex and comprehensive filter.

But that will not be necessary if you just plan on using it once in a blue moon, then investing in a highly complex water system will only be a waste of your money.

Carbon and sediment filters are usually the baseline of the least you should have in your water filter.

Understanding budget

Do not look at just the purchasing costs of a water filter but also the maintenance costs.

For example, you frequently have to change the filters inside your unit. You need to replace the lamps in a UV system once every year at the very least.

IF you have a carbon filter, it will start getting weaker after a while and will need to be replaced.

Suppose you have not taken these factors into account along with the previously mentioned ones. In that case, you will just be aimlessly shifting multiple water filters throughout the year, which is going to become extremely costly for you in the longer run.

Understanding ease of use/installation

Again, know for a fact that replacing the filter is going to eventually come in, whether three months later or a year, it is finally going to be something you have to do,

If you install a very hefty or hard-to-install kind of water filter, who is going to help you replace it after a while?

Either no one, in which case it will become a hassle for you, or you’ll have to call a professional plumber who will cost you many bucks.

So do ensure that you buy a filter that matches your expertise in the installation department.

FAQs on Best RV Water Filter

Is RV water safe to drink?

If you know that your tank and water system are clean and also have a treatment attached, the water is safe. If you rent an RV and are unsure about its history, this might not be the case.
If you are unaware of the history of your RV, just get a good water filtering system.

How do I maintain my RV water filter?

Just keep an eye out for issues. For example, if you see that your pressure or flow is dropping, it might be because the filtration system is getting clogged. In this case, you need to find a filter replacement immediately.
The easiest way to maintain is to just replace the filters at the recommended time given by the manufacturer.

What is the best filtration system for full-time RVers?

If you are someone who extensively camps out, it’s best to get a comprehensive filter with a higher capacity of how much water it can filter and a more comprehensive system.

What is a water pressure regulator?

As the name suggests, the pressure regulator is a small device that connects with the water source and controls the pressure of the water entering your home system.
This is done so that excessive pressure might not damage the plumbing within your RV.

Do I need a Water Pressure Regulator for my Caravan?

Technically, yes. It is better just to get one. Because you are using your RV to travel to different places, the pressure will keep on changing. It is also hard to determine what the pressure is in a specific area.
So it is better to save yourself the hassle and just get a pressure regulator once.

How much water should I filter for my RV?

It depends on what contaminates your water and for what purposes you’re going to use the water. Knowing these two answers will help you determine the final answer to this question.

Conclusion

Camping is a beautiful experience, and dirty, contaminated water can ruin it for you. This article discussed in detail all the essential things you need to know about filtering the water inside your RV.

Make sure to stay safe on all those fantastic camping adventures.
