There are many benefits of having a good quality RV Water Filter installed on your motorhome, campervan, or caravan. Not only does it improve the taste of your drinking H20 but it reduces the amount of space required by conventional portable camping systems which require large tanks filled with fresh tap water.

So, if you are looking for improved drinking water quality and peace of mind while on the road, then be sure to invest in a high-quality RV water filter.

Features to look for in a water filter for your RV

RV water filters are specially designed to remove contaminants from the water in your RV. RV water filters come in all shapes and sizes and there are a number of important factors you need to consider when choosing the right one for your needs.


The most important thing to consider when looking for an RV water filter is its capacity, meaning how much it can remove from the incoming water. For this purpose, you should look into what exactly you want to remove. Different types of filtration, which are described in detail below, have different capacities and can be used for different purposes.


The amount determined by this parameter should suit your individual needs perfectly because the stronger the purification is, the more it costs. If you don’t need a specific degree of purification then look at low-cost models that will do their job well enough without any unnecessary expenses.

Capacity is especially important if you are traveling with a large family or have pets that drink from the RV water supply.

It’s also crucial to consider how often your motorhome will be used and whether you’ll need to filter all the water that comes in or just some of it. If you’re only going to use the RV for weekend trips, then you might not need as much capacity as someone who takes long road trips throughout the year.

The most common capacities are 100,000 and 200,000 gallons for most types of water filters.

If you’re not sure what capacity you need, consult the manufacturer’s website or contact customer service.

Types of filtration

The next consideration for the best RV water filters is the type of filtration. There are three types of filtration: mechanical, chemical, and biological.

  • Mechanical filtration removes physical contaminants from the water, such as dirt, sand, and sediment. It uses a filter to strain out these objects. This is the most common type of filtration and is used in many home water treatment systems. Moreover, it is the most affordable type. But it is also the least effective at removing contaminants, such as bacteria and viruses. In addition, it does not remove toxic chemicals or metals from water.
  • Chemical filtration removes chemical contaminants from the water, such as chlorine and heavy metals. It uses a filter to remove these chemicals from your drinking water. This method is often used with other types of filtration (especially biological). A common example would be using carbon filters after passing through reverse osmosis membranes in order to clean up any remaining impurities—which can affect the taste and smell more than actual safety hazards for humans at typical levels found in tap water supplies across America (including those that test higher than EPA limits on occasion).
  • Biological filtration removes microorganisms like bacteria, viruses, cysts, parasites or fungi from your drinking water supply by filtering out their microscopic bodies before they can enter your body through ingestion. This is the most complex form of filtration and requires you to be very selective in choosing a system that can do this correctly without exposing you (and/or your family) to any possible health risks whatsoever. But if done correctly, it can be the most effective type of filtration when it comes to protecting you from harmful contaminants.

It is up to you to decide which type of filtration is best for your needs. But, if you are not sure, it is always a good idea to consult with a professional before making a decision.

Water Pressure

Another important fact to remember when shopping for the best RV water filter is that some units offer more powerful pressure than others. This means higher flow rates and better cooling of your drinking water, but it also means an increased chance of clogging if you use low-quality tap water. Some models are equipped with self-cleaning technologies or automatic backwashing systems to get rid of sediments and other blockages, but not all of them have those features.

Water pressure is important because it affects both the performance and durability of an RV water filter. You want a unit that can withstand high pressure, but you also need enough flow to make sure your drinking water tastes good and is safe for consumption.

Water Pressure

Water pressure is measured in pounds per square inch (psi) or bars. If you are not sure about the water pressure in your area, consult a professional or check online resources. The majority of RVers need at least 40 psi to ensure the proper function of their water systems, but if your RV has a high-flow rate faucet it is best to get a filter with a higher psi rating.

Some filters come with built-in gauges that tell you how much pressure is being put out, so be on the lookout for those. Otherwise, simply look for the maximum pressure number listed on the packaging or product description.

Most filters have a range between 30 and 80 psi, so as long your home’s water pressure falls within that, you’re good to go.

If your RV has a low-flow rate faucet, then consider getting a filter with a lower psi rating. This will help reduce the chances of the unit clogging up.


One more thing to consider is that some filters can be used on one or more water sources. For example, you might want to use the filter for your drinking water, but maybe also fill up at a stream while camping and bring it back into the RV. If this case applies to you then make sure the model of the filter matches all of your needs!

If there are options out there with different size hose attachments I would recommend getting an adapter so that no matter what type of faucet system you have in your home or campervan, they will work together seamlessly.

Moreover, there are filters that attach directly to the hose of your RV so you don’t have to mess with any attachments. These types are great for people who like a quick and easy setup, or if you plan on filling up your water tank from multiple outdoor sources.

But you should remember a few things about this system. If the water doesn’t flow through your filter fast enough, it might not be able to keep up and you will end up with a lower output of water from your tank. Also, if there is any pressure behind the incoming hose then that can also impact how much comes out!

Of course, all filters are going to have a different PSI rating as well which means they each need an intake hose running at this specific rate in order for them to work properly. This is especially true when looking at gravity-fed models versus those attached directly to your RV faucet itself. The former only move as quickly as its input source does while the latter has no such limitations unless there isn’t adequate pressure coming into the RV itself.

If you are worried about this then I recommend doing some research on the model before purchasing it to see if there is any mention of low flow issues or not having enough pressure for optimal use!

Life Expectancy

The next important thing to look at is the life expectancy of each type of filter. Some filters only last for a few months, while others can last for up to a year or more. It’s important to find a filter that will last as long as possible so you don’t have to worry about it constantly.

The best RV water filter will last between six months to a year or more.

Life Expectancy

When looking for a water filter, be sure to check its lifespan and how often it needs to be replaced. If you have a busy schedule, it might be best to go with a filter that doesn’t need to be replaced as often. However, if you don’t mind replacing the filter more often, then you can save money in the long run.

It all depends on your individual needs and what you’re looking for in a filter.

Kind of filtering system

The next critical factor to consider is the type of filtering system.

In general, there are three types for your consideration: Carbon Filter, Reverse Osmosis Filter and UV Light.

  • Carbon filters are the most common type of water filter used in RVs. An activated carbon filter is the cheapest, most effective kind of filtration system. It traps sediment and chemicals before they reach your water supply. A simple version for RVs includes a long hose with one end connected to your main line-in tapwater pipe leading into the camper, while it has another attached to an RV spigot that you can use as needed. The longer the first part of the tube is, the better will be its filtering capability since more particles will be trapped in between two points rather than just at one point only.
  • Reverse osmosis systems have several advantages over other types of treatment methods including their ability to produce high-quality filtered water at a fast rate. Moreover, it is the most efficient filtering system in removing chemicals, bacteria and even viruses. And best of all, they are not expensive at all compared to other types so you can have one installed right away. Reverse osmosis can be expensive, however.
  • UV filters are a newer option and they work by passing the water through an ultraviolet light that kills bacteria and pathogens in it. They’re typically less effective than carbon filtration systems because their process is too fast to remove all contaminants from your drinking source. That’s why this type of filtering system is often used in conjunction with other types. UV filtration is perhaps one of the best ways to ensure that no microorganisms or viruses remain in your drinking water once it has been treated with a reverse osmosis process. The downside? It can be quite expensive! You may want to consider this system for your future purchase if you’re planning on using untreated fresh lake or river water for cooking.

So, which type of filtering system should you choose for your RV? The best answer is that it depends on your needs and what’s available to you. If you’re looking for a cheap and easy option, then a carbon filter is probably the way to go. However, if you want the best possible water quality for your family, then you should consider a reverse osmosis system. UV filters are also a good option if you want to treat untreated freshwater.

Type of contaminants

The most common contaminants in water include bad taste, odors and minerals. For the purpose of removing these from your drinking water, a good RV filter is required. However, not all filters are created equal when it comes to filtering specific types of contaminants so you need to know what’s important for your needs before investing in one that will cost you more later on due to ineffective filtration.

In general, there are five main categories of harmful pollutants: sediment particles such as rust or sand; chemical pollutants like chlorine and fluoride; radioactive materials including uranium which can cause cancer; biological pathogens such as bacteria and viruses – Giardia being one example; heavy metals which comprise lead, mercury, and arsenic among others. These different types should be kept out of your drinking water and each has its own best filter for this purpose.

For example, one of the best ways to eliminate contaminants floating around in water is by using a filter for sediment. The most common form used on an RV would be one with a simple screen that prevents particles from getting into your drinking supply. Other types include filters that use electromagnetic technology which is very effective at removing small particles as well as those made up of carbon granules, also known as activated charcoal – these are better suited towards filtering out chemicals and bad odors than heavy metals or bacteria though so they should only be considered if you have concerns about things like chlorine or fluoride being present in your water.

Another popular option is reverse osmosis filtration. This works by forcing water through tiny straws called membrane fibers which trap larger pollutants and contaminants. The water that comes out on the other side is clean and pure but it also tends to be very acidic so a good quality RV filter should always be used afterward to adjust the pH level and make sure all the important minerals are still present.

Lastly, if you’re traveling in an area known to have high levels of uranium or other radioactive materials then a filter specifically designed to remove these particles from your drinking supply will be needed – otherwise, there’s a risk of ingesting them and developing cancer.

Treatments You Want

There are a few treatments you want in your RV water filter. The most important is that the filter removes sediment, dirt, and other particulates from the water. This will keep your drinking water clean and free of contaminants, as well as keep your tank clean.

You’ll also want a filter that eliminates chlorine and other chemicals from the water. These can have negative effects on both your health and your equipment, so it’s best to remove them before they have a chance to cause problems.

A third important treatment is that it removes any foul taste from the water. Sometimes, the smell or flavor of your drinking water can be unpleasant, so you’ll want a filter that gives you clean-tasting H20 on demand.

Treatments You Want

Finally, you’ll want a filter that kills any bacteria or viruses in the water. This is especially important if you’re traveling to remote areas or camping near bodies of fresh water. Make sure to choose a filter with adequate protection against these harmful organisms.


The last thing you want is for your RV water filter to break and have to go through the hassle of returning it and waiting for a new one. Make sure you check the warranty before purchasing. Most filters will come with a one-year warranty, but some can be as long as five years.

If you are looking for a permanent filter, make sure to find one that has a long warranty. This will ensure that you won’t have to worry about the filter breaking and not being able to use it.

Some filters also come with a money-back guarantee in case you aren’t happy with it. This is a good option if you aren’t sure about the water quality.

Most quality brands offer a limited lifetime warranty on their filters. This is a great selling point, especially if you plan on using the same filter for many years.
