The Best Under-Sink Water Filters for Clean Water from the Tap
There’s nothing more refreshing than a cold glass of water after a long day or a tough workout. But if the water coming out of your tap tastes a little less than fresh, you may want to invest in a water filter. There are a few different options out there, including filtering pitchers that you keep in your fridge, as well as larger countertop dispensers from brands like Brita and Pur. But keeping those filled can be a little tedious, especially if you drink a lot of water in a day. That’s why one of the best options is an under-sink water filter.
Setting up an under-sink water filter requires a little time and skill. You’ll need tools like wrenches, screwdrivers and Teflon tape, as well as enough patience to follow the instruction manual. But after the initial hassle of setting up the under-sink filter, you’ll enjoy the benefits of a continuous supply of clean, good-tasting water that flows right from the tap.
The kind of filter you choose will depend on your needs — if your city has a clean water supply but you just don’t like the taste, you can make do with a simple single-stage water filtration system. A single-stage system is easier to set up and less expensive. If you’re worried about heavier contaminants, then you may want a more advanced system, such as a dual-stage or a three-stage system.
We’ve rounded up some of the best under-sink water filtration systems, taking into account contaminants removed, cost, and ease of installation and filter replacement. These are the under-sink water filters to buy right now.
