Many modern refrigerators now come with a water tap that connects to the water line to provide chilled water on demand. While this system is amazing, you can make it even more convenient with a refrigerator water filter.

Refrigerator water filters are designed to ensure that the water that your fridge dispenses is not only chilled but also free of contaminant, odor and bad tastes. Hence, investing in the best refrigerator water filters is always a wise idea.

There are several types of refrigerator water filters out there, but the most common ones are grille, drop down, slide out and canister filters.

In this piece, we explain the factors to consider when choosing the right one for your home and also reviewing 12 top-rated models to help you make a more informed choice.

​What to Check Before Buying Best Refrigerator Water Filters?

​How to Buy the Best Refrigerator Water Filter

1. Compatibility

For the water filter to serve you well, it needs to work with your particular refrigerator brand and model. Hence, compatibility should always be one of the first factors to consider.

Finding a compatible water filter not only makes installation easy but also minimizes the likelihood of leaks and fitting problems.

Some water filters like Culligan IC-EZ-4 will have a universal fit or ideal for use with any refrigerators. But in note that in some cases, this is just a marketing gimmick that you should not fall prey to. So before settling for any water filter, make sure it is compatible with your brand and model number.

2. Filter Capacity

The filter capacity will determine how frequently you will need to change the filters. High capacity filters are the most convenient as they ensure you will go long without having to change them and this can also save you some cash.

While the capacity varies among different water filter types, brands and sizes, something that can filter at least 200 gallons should be good enough as you can go for up to 6 months without having to change the filter.

With that said, there are still some with a super high capacity out there like the Woder 10K-JG that can filter up to 10,000 gallons.

3. Filter Technology

Like with any other filter type, the refrigerator water filters will use different technologies to filter the water depending on the type and brand.

Activated carbon is the most common technology used on these filters. It works with other filtration mediums such as large mechanical filters that will remove the sediments and other large contaminants and the fine mechanical medium for getting rid of smaller elements.

When it comes to the filter technology, the most important thing to consider is its effectiveness in getting rid of different contaminant types. Also, check the size of particles that it can remove and the smaller the better.

4. Brand

Brand plays a crucial role when choosing a refrigerator water filter because not all manufacturers are known to produce high-quality filters.

The well-known companies that have been making these water filters for many years are often the best choice. This is because they have been in the business for long enough to understand what works best and also invest a lot of resources on research and product improvement to ensure they deliver the most efficient water filters.

Some of the best refrigerator water filter brands include Culligan, Frigidaire, General Electric, LG and Samsung. Also, note that most of these top brands are refrigerator manufacturers, and so they understand better what works with their different fridge models.

5. Ease of Use

A good refrigerator water filter is one that is easy to use and this means that it should be straightforward to install and replace.

You do not need to pay someone to install something as simple as this, and so you should always go for something that is not only quick and easy to install/replace but also comes with clear directions.

A simple, efficient, effective and user-friendly refrigerator water filter will always give you the easiest time.
