5 Best Under Sink Water Filters in 2024

Drinking water quality in the US is generally good because of the regulations set in place by the Environmental Protection Agency. Thanks to this, the water is mostly contaminant-free and safe for drinking directly from the tap. Yet, one can never be too cautious, especially when it’s about drinking water. So, if you find yourself in the same boat, investing in one of the best under sink water filters is not a bad idea.

Why Do You Need a Water Filter?

Under sink water filters are the easiest and most cost-effective way to treat water for drinking. Depending on the product of choice, under sink water filters can treat water coming in from unregulated sources such as a well and turn it into drinkable water.

These filters can also remove chemicals from the water such as chlorine that may have been added to it to remove bacteria. These chemicals, when added in high quantities, can change the taste of the water — something that water filters can fix.

One of the big reasons why we are recommending under sink water filters over other types of filters is because they can be placed under a counter and as such, help you save precious space in the kitchen.

Well, made up your mind already? But before you get to our list of the best under sink water filters, we recommend checking out some of our other posts as well.

The Frizzlife FK99 under sink water filter brings advanced filtration technology that bears the NSF 42 and 53 certification. Its filter also comes wrapped with a PP layer which is claimed to help the filter effectively remove 99% of the harmful contaminants from water.

These contaminants including chlorine can also give the water a bad taste and funky smell. Apart from this, lead and other heavy metals are also removed by the filter. All of this, however, without removing beneficial minerals from the water.

Unlike other options in its segment, the Frizzlife FK99 uses durable and lead-free brass fittings, which ensures there are fewer chances of cracks and leakage concerns in the long run. Plus, you also get an auto-shutoff function for when you’re replacing the filter.

It also uses KDF materials for filtration which can effectively reduce heavy metals, while resin in the filter can reduce fluorides. The company claims its CT filter has passed WQA certification to reduce residual chlorine and improve taste, thereby ensuring every drop is pure and healthy.

Additionally, because of its larger filtration area compared to the above options on our list, the Waterdrop TSA also provides flawless performance thanks to reduced risk of clogging. User reviews of the product such as this one on Amazon suggest this filter provides “clean and crisp drinking water.”
