Benefits of RV Water Filter

  • Keep the water clean. Having a water filter inside or outside your RV means you have access to clean filtered water. The drinking water from hookups at campsites or picnic areas may be full of organic compounds, such as sediment or chemicals, so RV water filters help flush out anything unwanted that may be in the line of the water filtration system.
  • Prevent clogs. A good, high-quality water filter will help prevent backups in water lines that lower the amount of water pressure you get. The filtration system works to block sediment and impurities from pouring into your drinking water. Without an RV water filter, the liquid may end up blocking the line and even damaging it.
  • Saves money. In the long run, having a recreational vehicle water filter kit may, in fact, save you money. As mentioned above, clogs could damage pipes and valves, but having a filter helps alleviate any unwanted things passing through the water line. That means they won’t get damaged, and you won’t have to spend cash to fix any repairs. You also don’t have to stock up on water bottles with a good water filter.

Types of RV Water Filter

Inline Filter

This fits directly to the motorhome’s water entry point to filter all the water supply entering the vehicle into a freshwater tank. An inline filter works to clean out sediment, chemicals, or harmful bacteria, making the water supply you drink taste better. It also gets rid of any unwanted odor that may come from water supply lines and hook-ups.

Compact Canister

A canister RV water filter fits onto the RV water hose outside or directly inside the RV’s water system. Another bonus is that they can be custom-fit to attach to faucets as well. Canisters vary in sizes and even come as a bundle of two or three for specifically designed filtration.

Reverse Osmosis

Reverse osmosis is the process by which water filtration units help to purify the water flowing to the RV. However, this does remove the minerals in the water; while it is not harmful to you, minerals are essential to our body’s metabolism.

Top Brands

Culligan

Culligan was founded in 1936 in Northbrook, Illinois by Emmett Culligan. Now headquartered in Rosemont, Illinois, it handles more than 1,000 dealerships and business offices in 85 countries. It makes the Culligan RV-800 Water Filter.

Clearsource

The company focuses on creating water filters to make sure customers get clean, safe-tasting water wherever they are. Clearsource is based out of Southern California and specifically designs filtration systems for RVs. One of its best products is the Clearcourse Premium RV Water Filter System.

RV Water Filter Pricing

  • $20-$35: RV water filters in this range will be smaller, giving you less filtration power, meaning it will take longer to filter out unwanted sediment and chemicals. These will more often be a compact canister design.
  • $35 and up: These are larger and more powerful filtration systems. They are more heavy-duty and come with more canisters to filter through the water supply.

Key Features

Filter Size

The size and weight of the container and filter cartridge will make a difference in the amount of water it’s able to filter from one hose to the other. While larger RV water filters may be better suited to filtrate the water supply, they are bulky and take up space. Making sure you have a place to stow it while traveling is a must. Also, keep in mind the number of canisters the filtration system has. The more canisters, the quicker the water is filtered to your RV.

Supply Source

Keep in mind how you’re getting your water supply. If you have to hook it up through an outside source at a campground, then having an inline water filter is best. However, if you just want to filter out the faucets and water supply inside the RV, using compact canisters is the way to go. They are lighter and much more compact, as the name suggests.

Other Considerations

  • Frequency of Use: If you’re planning a long trip or live out of an RV, making sure to stock up on filters or cleaning them often is something to keep in mind. The more people you have in the vehicle, the more it will be used. Having multiple filters or a backup replacement filter can help make sure you don’t run out of clean drinking water when you need it most.

This heavy-duty RV water filtration unit not only looks sleek but is also a go-to unit for many recreational vehicle campers. Its oversized body may look intimidating, but it’s simple to use and attaches to any RV hose quickly for tasty clean water. Plus, the heavy metal chassis makes it long-lasting and able to take bumps and scratches.

The Clearsource premium water filter comes with a two-stage filtration system to give you better tasting water that is odor-free.

The flow of the water is quick and seamless, meaning you get clean drinking water in no time at all.

However, some things to note are the size, weight, and the price of this RV water filter. It is on the heavier size, coming in at 17 pounds, and it is much more expensive than other water filters.

Best Value RV Water Filter: Camco TastePURE Water Filter

Camco TastePURE Water Filter
Amazon

Camco says this inline water filter is built to last an entire camping season, giving you months of fresh water to drink while you enjoy the outdoors. A feature we found that helps filter out water from campground hook-ups is the simple design of the container. While it isn’t large, the small but wide body allows the water to flow through quickly and effortlessly to your RV. 

The 20-micron granular-activated carbon filter removes bacteria, sediment, chlorine, and other chemicals from entering the water supply. Another benefit we found is the design also adds a sweet odor to the water. The kinetic degradation fluxion (KDF) technology is a high-purity copper-zinc formula that not only removes chemicals but also prevents the fungus from growing in the container. This will go a long way towards cleaning the filter as well. The filter can also be attached to any standard water or garden hose, so it can be used at home as well.

While this is a great bargain water filter, there have been reports of the hose leaking. It’s also recommended to run the water for 30 seconds to a minute each time before filling any drinking glasses. There have been mentions of a bad taste and odor coming from the water after having just turned it on.

Best RV Water Filter Honorable Mention: Culligan RV-800 Water Filter

Culligan RV-800 Water Filter
Amazon

This long-lasting inline water filtration unit cleans up to 2,000 gallons of water. That gives you an extended amount of camping time and less time to worry about cleaning the filter. The filter is easy to connect to RVs, boats, and camper units and provides a smooth flow of water pressure.

What we enjoyed about this water filter is the built-in bacteriostatic filter. The specially designed filter reduces bacteria, bad taste and odor, chlorine, and sediments from building up on the line and your drinking water. Culligan also backs this product with a five-year warranty.

We noticed with this particular brand of water filter, the water flow rate isn’t as fast as the others and the connector hose is on the shorter side, meaning you will have to purchase an extension hose or park closer to the water source. A flexible hose protector will help prevent leaks and will improve the flow of water.

Tips

  • Don’t get a water filter confused with a water purification system. While a filter will help make sure the water you drink is clean, a purification system works to make unsafe water safe to drink.
  • Be sure to clean the filter when advised. Running water through it after it’s recommended to change it can damage the hose or container.
  • If you have more people joining you during your camping trip, consider bringing more canisters or filters.
  • To get the best water possible, run the filtration system a few minutes before using it as drinking water. Dump out the dirty water until it looks clear. 

FAQs

Q: How often should I change my RV water filter?

A: Many models have an indicator, whether a light or noise, that alerts you to change the filter. However, if the taste or odor of the water changes, it may be time to swap out the filter.

Q: Can I use a water filter for hot water?

A: No, it is highly recommended that you do not run hot water through the filter. They are designed to handle cold water, and hotter water can reverse the process of chemical absorption. 

Q: How long does a filter last?

A: This is a difficult question to answer. It all depends on how often you use the water filter and how large the container is. Generally, an RV water filter will last three months, however, many can last up to six months.
