No More Pitchers To Fill: These Are The Best Water Filters That Attach To Your Faucet


Switching from bottled water to tap water is better for the environment (and your wallet), but tap water doesn’t always taste great and can sometimes contain potentially harmful contaminants — that's where filters come in handy. The best water faucet filters will improve taste and are third-party certified to remove contaminants while attaching easily to a faucet. Also important: They'll blend in with your kitchen aesthetic and require minimal maintenance

When choosing a water faucet filter, it’s helpful to look for ones that are third-party certified by NSF International and American National Standards Institute (NSF/ANSI). This organization provides different categories of certification, like standard 42 for limits on chlorine and improved taste and odor, standard 53 for reduction of volatile organic compounds (VOCs) and other health contaminants, and standard 372 for lead-free material. To make things simple, each of the picks below meets at least one of these standards, so you can rest assured your health is in good hands.

The next thing you'll want to consider is maintenance: Some filter cartridges last through 100 or 200 gallons of water and need to be changed every two or three months — but if you want a more long-lasting cartridge, you can opt for one that lasts through 320 gallons, or about six months. Some also come with helpful indicator lights to remind you when it's time to replace.

Whether you prefer a durable plastic filter or one with a sleek chrome finish, these are the best water faucet filters on Amazon that will remove many contaminants and make your tap water taste fresh and pure.
