Selecting the Best RV Water Filter

There are a few things to consider when you are getting started shopping for an RV water filter. I think that the first thing that you’ll want to take into consideration is the quality of water that you normally have access to. RV water filters vary widely, and some hook up to the kitchen tap, while others are larger systems that are a bit more expensive, but will do a better job filtering your water.

It’s also a good idea to consider the flow of the filter that you’re choosing. Some water filters will offer a great flow rate, which means that you don’t need to worry about taking forever to fill up your cup, while others go much slower. If you tend to be in a hurry, then I suggest looking for a water filter with a faster flow rate so that this doesn’t become an issue.

Benefits

Buying a high-quality RV water filter makes a lot of sense, no matter how much time you spend in your RV. You don’t want to be putting yourself or your family at risk of drinking contaminated water, which can easily happen when you’re in an RV.

In many places, you can only get high-quality drinking water if you are willing to pay a premium for it at the store. RVers, however, don’t want to have to stop in to the store every time they want water, which is why investing in a water filter is a good idea.

Water filters will remove sediment from your water and will quickly improve the taste and the odor of your drinking water. This is a great way to limit your exposure not only to dirt and debris, but also to bacteria, chlorine, and other pollutants that may be in your water.

When you install an RV water filter, then you won’t have to worry about water quality when you’re in a grid down situation. You and your family will be able to hit the road and know that you will have access to clean water, no matter what’s going on around you. This can be a literal lifesaver when you’re in a dangerous situation.

Additionally, by investing in a great water filter for your RV, you won’t have to worry about bringing your water with you on a trip. Bringing your desired water with you won’t just take up a lot of space, but it will also add weight to your RV, which will reduce your gas mileage.

When you invest in a filter, then you will be able to have all of the filtered water that you need without planning ahead to bring it with you, which is great for emergencies.

What to Look For

One thing that you’ll want to consider is how often you need to change the filter. If you spend time in your RV all year long, then a filter that only lasts for 250 gallons may not be the best option for you. There are some filters that can easily filter larger amounts of water, and you will want to consider one of these.

Additionally, check to see if it uses granulated active carbon, as this does a wonderful job not only removing debris from your water, but also making sure that it tastes and smells great.

I recommend that you consider the installation of the water filter you’re considering and make sure that you’re up to the task. Some RV water filters connect easily to the tap, while others are more advanced and require more effort and time. It’s important that you don’t buy a water filter that you’re going to struggle to use or to change.

Sediment filters are measured in microns, which tells the size of the particles they can remove. The smaller the micron rating on the filter, the better job it will do removing pollutants from your water.

How to Use Your New RV Water Filter

How you set up your new water filter will determine how it is used as well as where it is installed. No matter what, you need to make sure that you securely connect all of the tubes and connectors so that you don’t have any threading issues or leaks.

Make sure that you change the filter on a regular basis, or when suggested by the manufacturer so that you don’t have to worry about the filter not doing its job.

Considerations

The main problem that RVers have with their water filter is when they don’t change it often enough. It’s important that you not only change the filter on a regular basis to keep your water clean, but also that you winterize the system as necessary to prevent leaks and damage to your filter.
