10 best RV water filters | Reviews inline RV water filter system

Fresh and clean water can be hard to come by in campsites at times. However, access to clean water is essential to ensure the safety of everyone in our RVing adventure. No one would like to see brown water coming out of the faucet nor drink smelly and poor tasting water.

No one wants dirty, muddy, or foul-smelling water either. They can be health dangers that can put us at risk. These contaminants can also affect our RV’s plumbing system. To prevent all these issues, we need the best RV water filter. We’re helping you choose one in this guide.

What is the Best RV Water Filter?

Best RV Water Filter

The best ones are filtration systems that can get rid of water contaminants, which would otherwise be supplied to our faucets. They work hard to enhance the taste and smell of our RV’s water supply. They can also remove sediment and reduce chlorine, keeping our appliances and plumbing from clogging. That’s not all because these RV water filters can prevent their premature damage and failure. Best of all, they can save us money in the end for avoiding hefty repairs and replacements.

Types of RV Water Filters

Types Of RV Water Filters

RV water filters can be classified into two: physical filters and chemical filters. Physical filtration improves the water’s taste and odor because it filters out debris, dirt, sand, sediments, and other particles floating in the water.

On the other hand, chemical filters usually release a chemical into the water supply to improve its quality. As such, it gets rid of bacteria, chemicals, microorganisms, minerals, and the like. Here are the common filters you can find in most models:

Carbon Filters: Carbon filters are known to be the best in improving your water’s taste and odor. The filter itself is either: 1) granulated activated carbon; 2) modified block of carbon; and 3) a solid block of carbon. The first carbon filter type is the most common and the cheapest; however, they are not the most effective. Carbon blocks are more effective, but they are also more expensive.

UV Purification: Ultraviolet purification systems deal with the bacteria, microbes, and other microorganisms found in your water supply. Through radiation, this water filter breaks them down to sterilize the water.

Reverse Osmosis Filters: Reverse osmosis filters are the most advanced filters currently. They come with a semi-permeable membrane that effectively blocks large and small particles and contaminants.

The only thing these filters cannot remove is chlorine. So, if you want a reverse osmosis filter, make sure that it also comes with carbon for chlorine and chloramine removal.

Reverse osmosi: This process of purification involves using a permeable membrane that works to separate the unwanted molecules, ions, and larger particles from the drinking water.

Ceramic Filters: Ceramic filters are effective in removing bacteria and microorganisms due to their material. However, they aren’t as effective when it comes to chemicals.

For best results, ensure that it comes with a carbon filter to increase its efficiency.

Which RV Water Filter is Right for You?

As many avid RV travelers know, having access to a clean water supply is usually impossible while you’re traveling – especially in remote areas. One way to avoid getting sick is by installing an RV water filter in your vehicle.

There are numerous water filter models in the market; however, this wide range of choices can make it confusing and complicated.

Luckily, this buying guide will enumerate the factors you need to look for when buying an RV water filter.

  • Filter Capacity

    Filter CapacityThe kind of filter you want to install in your RV depends on how much water you want to filter.

    If you plan on filtering all the water entering your RV, then a multi-canister system or inline filter is our best bet. Their large capacities also mean that they tend to be expensive.

    However, filtering your whole RV can be advantageous as it protects the vehicle’s pipes from calcium or sediment build-up.

    If you only want to filter specific water entry points, such as the kitchen or the bathroom, then a countertop filter or an under-sink filtration system will work. These options tend to be cheaper and more practical for many RV owners.

  • Frequency Of Use

    You should also consider how often you want to use your filter.

    Advanced setups are excellent choices if you travel or plan to travel full-time. These systems tend to be more thorough and come with numerous features to enable you to tackle various water quality issues. But remember, the more features it has, the more expensive it will be.

    More advanced setups are also a must if you tend to travel in remote areas or off-the-grid locations.

    On the other hand, if you don’t often travel or just travel near cities, then a simple setup will suit you. Simple systems have the necessary features that will filter out your water supply. Moreover, you can always just run to a convenience store for a refill.

  • Micron Rating

    Micron RatingA filter’s micron rating is a vital factor you need to remember. This feature indicates the size of the particles or sediments that can pass through the filter membrane.

    For example, a filter with a 0.1-micron rating filters more effectively in contrast to a model with a 2-micron rating.

    Some RV water filters even have submicron ratings, indicating that they can block out the tiniest of particles, resulting in clean and fresh water.

  • Easy to Install and Use

    Installing RV water filters can be burdensome. So, unless you are a plumbing expert or just an all-around tinker, you might want a filter that’s simple and easy to install.

    Wrong or improper installations can affect the water filter’s effectiveness. If it leaks and is unchecked, it can lead to mold or mildew build-up and contaminate your filtered water.

    Inline water systems are usually easy to install. You would not even have to open or dismantle your RV’s plumbing system. Screw the water filter in place, and you are finished.

  • Price (And Cost Over Time)

    Let’s face it – RV water filters can be quite a bit pricey. Even the cheapest ones are still more costly compared to water filters used in traditional homes.

    However, it is essential to look past the initial cost. Some water filters might be expensive upfront, but their features make up for it in the long run. For example, filter A might be more expensive, but they cost less to care for or maintain.

How to Change the RV Water Filter?

Installing or replacing your RV water filter depends on the model. As such, you must consult the manual or call the manufacturer first before you install or replace your water filter. Nevertheless, they all have similar steps that include the following.

  • Turn off the water supply and unscrew the water filter’s housingStep 1: Turn off the water supply and unscrew the water filter’s housing.
  • Drain it out of the water and check the bottom of the canisterStep 2: Drain it out of the water and check the bottom of the canister. Rinse it if you see any lingering sediments or particles. Be mindful of the O-ring at the top and make sure that it stays in place.
  • Carefully remove the old filter from the housing and replace it with a new oneStep 3: Carefully remove the old filter from the housing and replace it with a new one.
  • Screw the housing back into placeStep 4: Screw the housing back into place, ensuring that it is screwed tight and without gaps.
  • recommend replacingStep 5: Manufacturers recommend replacing the filter every three to six months. However, this depends on how much water you are filtering and how often you use it.

Frequently Asked Questions about RV Water Filters

Do you need a water filter on RV?

Yes, you do need a water filter on your RV.

Unlike traditional homes, RVs and motorhomes do not have a steady clean water supply. You will inevitably have to replace and refill your supply the longer you stay on the road.

During those times, you’ll be getting water from unfamiliar and potentially unclean sources. Installing an RV water filter will ensure the quality of your water, avoiding and preventing any diseases.

How long do RV water filters last?

An RV water filter’s lifespan is usually indicated in its manual. Depending on the manufacturer, some models can last for as short as three months, while others can go on for two years.

However, keep in mind that this lifespan is a mere estimate. Thus, it can shorten or lengthen depending on how well the user takes care of and maintains the filter.

Regardless of whether it has a long lifespan or not, many RV owners recommend replacing the water filter every three to six months, especially when regularly in use.

Over time, the filters can deteriorate, which affects their performance.

What do RV water filters remove?

It depends on the model. Some RV water filters rely on the physical filtration method. These filters remove dirt, debris, rust, sediments, and other large particulates out of the water. Some physical filters also remove chlorine and chloramine to enhance the water’s taste and smell.

Other models work on chemical filtration where they release certain chemicals to treat the water supply. It gets rid of bacteria, microorganisms, and contaminants in the water.

For best results, many recommend purchasing a model that uses both filtration methods.

Which water filter removes the most contaminants?

Water filters generally have two filtration methods: physical and chemical filtration.

Physical filters improve the water’s taste and odor since it removes dirt, debris, sediments, and other large particles you see in the water. Some models also have the bonus of removing chlorine and chloramine to enhance the water’s smell and taste.

On the other hand, chemical filtration eliminates bacteria, chemicals, microbes, and other microorganisms to ensure clean water.

A good water filter must have both systems. Hence, most RV owners opt to purchase RV waters systems with two- to three- filtration stages.

Which brand of water filter is best?

Out of all the RV water filters on the list, the Camco 40043 TastePure is the best.

This inline filter is known for its versatility and user-friendliness. You can even install it by yourself by simply attaching it to any standard garden hose.

Aside from this, the Camco 40043 proves to be an effective filter as it can remove bacteria, chemicals, debris, dirt, sediments, and contaminants. With this, you can easily access clean and fresh water.

Waterdrop is also a well-known brand due to its high-technology and effective products. The Waterdrop WD-RVS-1, TSU, and G2 water filters boast high-efficiency ratings due to their multi-stage filtration. However, they tend to be quite expensive and may require a bit of plumbing during installation.

Nobody likes to drink foul-tasting and potentially bacteria-infested water. As such, purchasing and installing a water filter for your RV is an ideal investment. Hopefully, this guide was able to help you in deciding what RV water filter to get. Happy travels!
