Why You Need an RV Water Filter

RV owners frequently ask questions like “why do I need an RV water filter?” or “how good are RV water filters?”

While traveling, access to safe drinking water is necessary. Buying large gallons of bottled water is expensive, leads to plastic waste, and requires a lot of effort on your part.

Moreover, if you decide to camp or find yourself in a remote area where basic amenities are hard to come by, getting clean water to drink can be a luxury. As a result, people tend to rely on tap water which may be contaminated and brings a host of problems with it.

Illnesses From Contaminated Water

Contracting illnesses due to harmful bacteria or protozoa can cause severe discomfort to the stomach including diarrhea. In addition, diseases such as giardia or cryptosporidium can lead to serious dehydration which can lead to other health problems.

To avoid facing these issues while traveling, it is recommended that you install an RV water filter in your vehicle. Although it can be expensive, the benefits of the filter far outweigh the costs. With an RV filter, you will have access to safe drinking water all the time, which you can also use to cook and clean. Most RV filters are easy to install, can easily fit in small spaces, and require minimal maintenance.

Hence, the best way to enjoy your trip is to install a reliable good-quality RV water filter so that you can be assured of access to potable water at all times.

Types of RV Water Filters

In general, there are five types of RV water filters:

  • Interior water filters
  • Exterior water filters
  • UV filters
  • RO filters
  • Activated carbon filters

Let us understand each of these filter types in detail.

Interior vs Exterior Filter

An interior filter or an internal filter is a filter that is installed at the point where the water from outside enters the RV filter. An internal RV water filter is advantageous as one can easily install a filter that has a large capacity and thus delivers more water.

An exterior RV water filter, on the other hand, is a filtration system wherein the filter can be attached directly to the hose that brings water into your RV. This system of filtration is installed outside the RV.

UV Filter

A UV filter makes use of an ultraviolet purification system to neutralize dirt and germs present in water.

A UV water filter is best for places where the water has a large number of microorganisms such as bacteria, viruses, and fungi. The filter then neutralizes and kills these organisms by exposing them to germicidal ultraviolet wavelengths.

Moreover, the UV lamps present in the filter use radiation to disrupt the genetic coding of microorganisms present in the water. This prevents them from multiplying and further contaminating the water.

Although a UV filter will eliminate potentially harmful dirt and organisms, it will not change or improve the taste of your water.

RO Filter

An RO filter uses a reverse osmosis system to purify the water in your RV water filter. In the reverse osmosis system, the water is forced to pass through a semipermeable membrane that is made up of several small pores. These pores filter out all the dissolved salts and solid particles from the water.

A sediment filter in an RO filter extracts all the residue from the water while the carbon post filter improves the taste of water after all the dirt and germs have been extracted.

An RO water filter requires a separate storage tank along with a booster pump to flush out all the wastewater.

Activated Carbon Filter

An activated carbon filter is best for those who are not only looking for potable water but also want the water to taste good.

In an activated carbon filter, chemicals such as chlorine along with dirt particles are removed through a process called adsorption. Since activated carbon filters are gravity-fed, they are also capable of removing cysts, bacteria, heavy metals, and fluoride from the water.

Activated carbon filters are slowly becoming popular as they don’t require electricity to operate, and can be filled and used multiple times.

Portable Filters

A portable RV filter is great for people who are always traveling. For such people, a heavy RV filter can be difficult to carry and install, hence, a portable filter works best.

With a portable RV filter, you can fill your water bottle from anywhere and clean it using your RV filter. You can also carry it along with you whether you are traveling with an RV or not.

About Filter Capacity and Micron Ratings

Filter capacity and micron ratings are two important aspects that one should never overlook when reviewing possible filtration systems for their RVs. These two factors significantly impact your RV’s filtration system, its upkeep, and the quality of the water you will have.

Filter Capacity

Once you have decided what type of RV filter works best for you, it is important to determine the filter capacity you need.

If you want a filter that simply removes unclean water for cooking and drinking, then you can get an under-the-sink RV filter. On the other hand, if you are looking for an RV filter that removes all the dirty water from your RV, then you will either require an inline filter or a canister-style system.

The amount of water you’ll need should also be taken into account when determining filter capacity. Regular travelers or those traveling for long distances will need a large-capacity, durable RV filter. On the other hand, infrequent travelers who intend to remain within city limits will require smaller-sized and simpler RV filters.

Micron Ratings

The micron rating of an RV filter helps you understand the size of the particles that can pass through the filter. Thus, if you see that your RV filter has a micron rating of 0.1, this means that it will filter a higher number of particles than a filter that has a micron rating of 2.

How Long Do RV Filters Last and How Often Should You Replace Them?

An important question that most travelers have is how long their RV filters will last and how often they should be replaced.

The answers to both questions depend on the usage of the RV filter. Most brands conveniently mention the durability and life expectancy of their RV filters on their packaging. Many RV filters last anywhere from 3 to 6 months.

For the sake of your health, you are encouraged to heed your filter’s service life based on manufacturer recommendations. Replace your filter every 3 to 6 months of use. A filter that has not been used for a long time can cause it to malfunction or become a host to dirt, dust, germs, and other harmful microorganisms.


An RV filter is suitable for people who are always on the road and may not always have access to clean drinking water. RV filters are generally easy to install, affordable, and can also be transported from one place to another. Today, many RV filters boast innovative technologies that eliminate harmful dirt, germs, and chemicals while improving the taste of the water.

Before you head out for your next road trip, don’t forget to look for, purchase, and install an RV water filter according to your needs. Filtration systems are necessary and convenient to have around. The next time you’re out in the middle of nowhere, you’ll be glad to have one along for the ride.
