Hydroviv water filtration systems are the only water filters where Water Nerds examine your city's water quality data before the system is built (using your shipping address), to ensure the system performs optimally. Water isn't one-size-fits-all; your filter shouldn't be either.

Note: If you are on a private well, please specify in the "Order Notes" section during checkout. We will use a different set of data to optimize your filter, including geological assessments from USGS and internal data.

Hydroviv drinking water filters meet industry standard filtration performance specifications for lead, chromium 6, arsenic, VOCs, mercury, and cysts. Hydroviv systems have also been independently tested against PFAS (including GenX and other emerging contaminants).

Hydroviv's water filtration systems are proudly hand-built in our Knoxville, TN facility, using NSF-certified housing materials and filtration media.

You can buy with confidence knowing that there is a 30-day, no-questions-asked, money-back guarantee on any purchase, and that our housings/hardware have a 5-year warranty as well.

Undersink System

Hydroviv's undersink filtration system connects to the underside of a lead-free faucet in about 15 minutes using simple screw-on connections that do not damage plumbing (installation video here).

These under sink filtration systems only require a space that is 14 x 6 x 6 inches, so they can fit under any sink or bathroom vanity, even if you have a garbage disposal.

Cartridges last 6 months under normal usage, and water filter replacement cartridges can be purchased online. Sign up for a subscription and you will automatically receive replacements every 6 months (and save 30%).

Fridge Line System

This filter is designed to be installed in a cabinet adjacent to the refrigerator or in the floor below. Installing the water filter for your ice maker behind the refrigerator will cause the appliance to stick out an additional 6 inches.

This refrigerator ice maker water filter connects to your refrigerator's water line (plastic tube or braided stainless steel line) using screw-on 1/4 inch compression connections. Installation videos can be found here.

Cartridge lasts 6 months under normal usage, and replacement filter cartridges can be purchased here.
