Countertop Water Filter Systems

Enjoy healthy, clean water with a countertop water filter from Discount Filter Store.

Countertop water filters are one of the most popular and widely used water filters today. The advantage of having a countertop water filter system is that they are extremely easy to install, less likely to clog than faucet filters and water pitchers, and they’re able to filter large quantities of water relatively quickly and without modifying your plumbing.

At Discount Filter Store we carry over 20+ of the industry’s most popular countertop water filters including the H2O Cypress Water Filter System, the Doulton HCP SuperCarb Filter System, and more.
