Single Undersink Carbon Water Filter System (GT1-15WM)

Enjoy cleaner, fresher-tasting water straight from your tap with this premium Undersink Water Filter Kit from High Performance Filtration (HPF). Featuring a WaterMark certified housing and a top-tier 1 micron 100% Coconut Carbon Block Filter, this compact system is ideal for reducing chlorine, taste, odour, and other common town water impurities.

The included 1 micron coconut carbon filter is made entirely from activated coconut shell carbon—renowned for its high adsorption capacity, longer service life, and superior ability to improve taste and odour. Unlike many cheaper filters on the market that use a coal-blend media, this is a 100% pure coconut carbon block, delivering high-performance filtration with low pressure drop.

Perfect for households on mains water supply, this undersink kit is easy to install, compact, and comes with everything you need for a standard setup—including a WaterMark approved pressure limiting valve and dedicated drinking water faucet. It’s the ideal solution for homes seeking a reliable, cost-effective drinking water system without compromise.
