How to Choose Your RV Water Filter?

There are certain factors that contribute to the quality of an RV water filter. Knowing what those factors are will help you choose a reliable product that would also be able to meet your specific needs. So, here are a few tips to help you choose the best RV water filter.

Types of RV Water Filters

RV water filters use different technologies for the removal of water impurities. Knowing the types of RV water filters available and the contaminants that they can remove will help you choose the right one for your needs.

1. Sediment Filter

All water filters come with a sediment filtration layer. This is the most basic type of filtration that is designed to catch the bigger particles. It works as a strainer, removing any sand, dirt, and other contaminants that leave the water dirty and untasty.

It’s important that a filter includes this sediment removal layer. Otherwise, sediment can wreak havoc on your RV’s plumbing and appliances. Sediment can also reduce the effectiveness of other filtration parts, such as the granular activated carbon. It will quickly exhaust, making it ineffective. Due to this, it’s essential for any water filtration system to have a sediment filter.

2. Activated Carbon

Another important part of RV water filtration systems is a granular activated carbon layer. It does more than sediment filtration, removing smaller particles from the water.

One of the major benefits of carbon filters is their ability to remove chlorine and chloramines. This also expels foul odors and improves the water’s taste. Just sediment filtration can’t achieve this. That’s why these two filtration technologies are most often combined together.

Certain carbon filters are also capable of removing other water contaminants. They can include heavy metals, lead, asbestos, mercury, and volatile organic compounds. However, the contaminants a carbon filter can actually remove and its efficiency depend on its type.

There are three typical carbon filter types. The most common one is the granular activated carbon type. It’s not the most efficient one but it is commonly used due to its cheaper price. It features grains of charcoal.

As the water passes through, it catches the contaminants. Depending on the filter, it can catch contaminants down to 20 or 5 microns in size. However, the minimal surface area of the activated carbon makes this type of filtration system less effective compared to certain other types.

Carbon filters can also have solid block carbon. It’s made using pulverized carbon, which is shaped into a block under pressure. This type features a broader surface area, which ensures that all of the water passes through the activated carbon, reducing more of the contaminants.

As for the third type, it features a modified carbon block. This type works in a similar way to the solid carbon block filter, but it offers a higher flow rate and better durability.

3. Ceramic

Some water filters additionally offer ceramic filtration. This type features a screen with tiny holes, which removes bacteria, protozoa and sediments. However, it’s not as effective at removing chemicals in the water. And some ceramic filters don’t filter any chemicals from water at all.

4. KDF Technology

This technology uses a unique copper zinc formulation, which creates an electro-chemical reaction. This process is known as redox. During redox, electrons are transferred between molecules, changing them into different elements.

Some of the contaminants are converted into harmless components. For example, chlorine is changed into water-soluble chloride, making it harmless. Other contaminants are electronically bound to the KDF media, effectively removing them from the water’s supply. These contaminants can include heavy metals, hydrogen sulfide, iron, and more.

Another benefit of KDF media is that it controls the growth of bacteria, fungi, and scale. Since KDF is usually used in conjunction with carbon filtration, this technology also helps to extend the life and lower the maintenance of the carbon system.

Micron Rating

Water filters usually feature a micron rating, which refers to the maximum size of the particles in the water that the system will let pass. This means that the lower the micron rating, the more effective will be the filtration, with more contaminants caught by the system. A filter with a 5 micron media is better than one with a 20 micron media.


Think of how much water you need to filter for your RV use and choose a filter with appropriate capacity. Some filters offer a capacity of only 500 gallons, while others can filter as much as 2,000 gallons.

If you use water in your RV sparingly, then 500 gallons might be enough for you to last an entire camping season. On the other hand, if you have a big family and you use a lot of water, then you might consider choosing a 2,000 gallons water filter.

When considering the capacity, also think of how long a filter would last. Depending on the water quality and your water usage, some filters list about 3 months, while others can last 6 months and more.

Water Flow

Water flow is also an important factor. You don’t want it to be so slow that it would take forever to get the filtered water into your fresh water tank.


It will be best if you can install your new RV water filter with minimal hassle. Remember that you’ll need to regularly replace the filter since they usually have a lifespan of 3 to 6 months. Due to this, you want to choose a system that would be very easy to install. If you choose an overly complicated filter, you’ll just end up with a lot of frustration. And this frustration can be avoided.

If you buy an in-line water filter, most of them feature very simple installation. The process is similar for all of them. You install one end to a hose that supplies the water and the other end to a hose that supplies the filtered water into your RV’s fresh water tank.

For ease of installation, it’s also important that the RV water filter comes with an instruction manual. This would provide you with detailed step-by-step recommendations on how to set up the system.

To understand whether a filter would be a breeze or a hassle to install, you can check user reviews and RV water filter ratings. In them, you can usually find information on whether the users had any problems with the installation process.


Consider also the size and weight of the water filter. A larger filter body usually means that it can allow more water to pass through it at a time, resulting in a higher flow rate. However, with a filter that is too bulky, it can be difficult to find for it proper storage. So, consider the size of the filter and make sure that you have enough space in your RV’s storage to stow it away when it’s not in use.


As when buying anything else, the price of the water filter also matters. Setting yourself a certain budget is a good way to ensure that you don’t overspend. It’s also a good way to save yourself time since it will allow you to narrow down your options to only those that are within your budget. This would also make the process of choosing the right RV water filter an easier process.

However, it’s also not a good idea to just settle for the cheapest water filter. It should also be of good quality and value. That’s why look for an RV water filter that would offer the best combination of price and value.


Lastly, consider the brand. Buying from a reputable and trusted brand, you have a higher chance of getting a high quality RV water filter that would provide long lasting performance.

Brands that have built a reliable reputation are usually committed to delivering high quality and durable products. They also often show that commitment by providing good warranties. This can give you peace of mind that if you get a defective water filter, the manufacturer would be able to offer you a replacement.

RV Water Filter Frequently Asked Questions

What is an RV water filter?

An RV water filter is an essential piece of equipment for any caravan, trailer, camper or any other recreation vehicle that has a water hookup. Whether you’re getting your water supply from a campground’s source or any other place, the filter will ensure that the water you get is safe for drinking. It will also ensure that you have a supply of safe drinking water whenever you need it.

The function of these water filters is to remove suspended contaminants that make the water undrinkable. The contaminants they remove can include sediment, chlorine, heavy metals, volatile compounds, and other impurities.

They can use different technologies for filtration. It can include granular activated carbon, KDF, and other technologies that are designed to remove specific contaminants.

Most of the RV water filters feature an in-line design, meaning that they are installed in between the water source and your RV’s fresh water tank. This provides a streamlined water flow to all fixtures in your RV.

How does a water filter work?

There are two main techniques used by RV water filtration systems.

  1. The first one involves physical filtration. During this process, the water passes through a barrier that acts as a strainer. This membrane features tiny holes that allow the water to pass through while catching bigger suspended particles. As a result, the membrane removes from the water larger impurities, such as sediment, sand, and dirt.
  2. The second technique features chemical filtration. As the water passes through an active material, such as activated carbon, it creates a chemical reaction. The result of this reaction is that some of the contaminants become harmless, while others get bound to the membrane, removing them from the water.

In most cases, water filtration systems combine both of these techniques. This allows them to remove both larger and smaller particles from the water, resulting in cleaner and safer water.

What are the benefits of RV water filters?

Having clean drinking water is important to everyone. It’s also important to RV owners who never know what the quality of water is that different campgrounds offer. That’s why there are a lot of advantages to installing an RV water filter. Here are some of them.

  1. Removes sediment. Sediment is what causes cloudy and dirty water. It makes the water undrinkable. It can also be damaging to your RV’s equipment and plumbing system, resulting in higher costs for repairs and replacements. An RV water filter helps to prevent all these issues by removing the sediment and other similar particles from the water.
  2. Removes chlorine. Most campgrounds and other water sources have chlorinated water. It’s usually used to treat the water for removing contaminants and pollution. However, highly chlorinated water doesn’t taste good and it has an unpleasant odor. A good water filtration system would remove chlorine from your drinking water supply, as well as its foul odor and taste.
  3. Reduces bacteria, heavy metals, and VOCs. In addition to sediment and chlorine, water filters remove other contaminants. They can remove harmful organisms, organic compounds, and chemicals. They help to flush out anything unwanted, giving you access to clean filtered water.
  4. Gives You a Peace of Mind. While on the road, you might not always have access to clean drinking water. You can’t also always depend on the quality of the water coming from a campground’s water supply. Due to this, having a water filter will set your mind at ease since it will guarantee access to safe drinking water no matter where you are camping. This would allow you to enjoy your adventures without worrying about where you’ll be getting fresh filtered drinking water.
  5. Protects your RV’s plumbing system. As we’ve mentioned, sediment can be terrible for your RV’s plumbing. It can clog up the pipes, which would then require expensive repairs. It can also contaminate your fresh water tank. As a result, you’ll have poorer water quality.
  6. Is an environmentally friendly option. With an RV water filter, you won’t have to rely on bottled water anymore. This would allow you to cut on all that plastic going to waste, which would be better for the environment. On top of that, you’ll no longer have to carry all those heavy packs of bottled water.
  7. Allows you to save money. First of all, you’ll be saving money on all the costly repairs that you otherwise have with all the sediment wreaking havoc on the plumbing system. Secondly, you’ll also be saving money because you’ll no longer need the expensive bottled water.

How long do RV water filters last?

It depends on the water filter you’re buying. They can last anywhere from 3 to 12 months. And how long it will actually last depends on several factors.

First, it depends on the quality and capacity of the water filter. They are designed to filter a certain amount of water before becoming ineffective.

Secondly, it also depends on your water usage. The more water you use, the shorter will be the lifespan of the water filter since you’ll be using up its capacity at a faster rate.

And thirdly, the quality of your water supply also plays an important role. Highly contaminated water will put more strain on the filter, shortening its lifespan.

Generally, it’s recommended to replace an RV water filter every 3 months. However, depending on your situation, it might be longer or shorter. A good indication that it’s time for a replacement is when the water flow slows down or when you notice a change in the water’s taste and odor.

What are good RV water filter brands?

There are plenty of RV water filter brands competing for the attention of buyers. However, not all of them deliver high quality products. There are a few popular brands that have built a solid reputation by offering highly effective water filters. These brands include Camco, Culligan, and Clearsource.

How to install an RV water filter?

The installation of most RV water filters is usually an uncomplicated and easy process. However, since the process can still differ from one product to another, it’s highly recommended that you can check the user manual that came with your specific water filter. There, you’ll find the instructions that you should follow to ensure the proper operation of the system.

In-line RV water filters fit onto the external water hose leading into your vehicle’s fresh water tank. As a result, the water through one end of the filter and after filtration comes at the other end, delivering a clean supply of clean water.

Can I use the RV water filter for hot water?

Water filters are not designed for filtering hot water. Hot water can reverse the process of chemical absorption, making the filtration ineffective. That’s why you should never use an RV water filter for hot water.

Is it practical to filter all the water in my RV?

Filtering all the water for your RV adds a lot of convenience. As a result, you’ll have clean water not only for drinking, but also for cooking, showering, and washing. Another advantage of this is that you’ll have clean water that is free of sediment flowing through your RV’s plumbing system. For this application, you should purchase a water filter system that would filter all water coming directly into your camper.

On the other hand, if you want to filter only drinking water, you might need just a system for your kitchen sink. This can be a good option if you think that the quality of your water supply is not that bad.

In the end, the answer to this question is down to your preference and needs. However, in our opinion, filtering all water coming into an RV is a better option.

Can I use reverse osmosis for RV?

RV water filters can only filter the water. They don’t offer water purification. That’s why some RV owners consider installing a reverse osmosis system, which does that. It uses a water purification process to deliver pure, good tasting water.

However, while these systems are popular among homeowners, they are not that often used in RVs. There are two main reasons for that.

First of all, these reverse osmosis systems can be really expensive. While an in-line RV water filter can buy at around 15 to 30 dollars, a reverse osmosis purification system will cost you 300 dollars and more. That’s a huge difference that a lot of people are not ready to spend.

Secondly, the system creates a lot of wastewater. The removed salts, pollutants, and minerals make up the brine or wastewater. This wastewater requires draining from the system. And for every gallon that the reverse osmosis system purifies, it creates four gallons of brine.

That is a lot of water that gets wasted. And if you’re RV camping, you’d probably want to use the water sparingly. Due to this, if you want highly purified water, a reverse osmosis system might be a good idea. However, considering the price and the high waste of water, we’d choose an external in-line filter instead.

How to replace an RV water filter?

If you’re using a canister water filter, then the replacement process would involve removing the old and adding the new cartridge. To do this, start by removing the canister that holds the cartridge using a wrench. Discard the old cartridge and wash the canister before inserting the new filtering element. If there are two canisters in the system, make sure that the two cartridges are placed in the right canisters. Then, screw the canister back onto the head of the mount and tighten it in place.

How do you clean an RV water filter?

To get proper instructions, it’s better to consult the manual that came with your product. With so many different types of RV water filters, the process will be different for many of them.

Fortunately, in most situations, cleaning is an easy process. It requires backflushing the filter for flushing away the accumulated gunk. You can use a hose or a syringe for reversing the flow. If the filter permits it, you can also additionally use a brush to remove some of the buildup. However, do make sure that your filter is suitable for it and if it, use only a soft brush.

Camco 40043 vs Camco 40045: which one to buy?

The two most popular Camco RV water filters are 40043 and 40045. These two units excel in both functionality and quality. They also feature a similar in-line design that delivers a streamlined water flow. On top of that, they use the same method of water filtration that includes a sediment barrier, GAC, and KDF. But what is the difference between them?

The main difference between the two is in the flexible hose connector. The 40043 option includes it, while the 40045 doesn’t. Moreover, the 40043 comes with only one filter, but the 40035 water filter comes as a two-pack.

Camco 40043 vs Camco 40013: which one to buy?

Another popular Camco product is the Camco 40013. But how does it compare to Camco 40013? And what is the difference?

Both filters are actually the same. They use the same filtration method, have the same water flow and capacity, and they both include a flexible hose connector. And the difference is just in the packaging.
