Most under sink water filters require a dedicated drinking water faucet, but not our full flow systems & cartridges. Now you can install an Everpure Water Filter system directly to your existing faucets to get the same great tasting water from your faucet’s cold water side. The days of drilling the counter and having a dedicated faucet are old news! You can also upgrade to any of the replacement water filter cartridges listed here for increased capacity!
