Conveniently access cleaner, refreshing water with the PUR 4-Stage Universal Reverse Osmosis (RO) Water Filtration System. This under sink 4-stage RO water filter system delivers more purified water through a secondary air gap faucet. Forget bottled water and opt for an environmentally sound water filtration system that is NSF certified to reduce multiple unwanted contaminants including lead, cysts, TDS and heavy metals. During stage 1, the 5-micron sediment filter acts as a sieve to reduce particulates such as rust, sand and dirt. In stage 2, the 5-micron carbon block filter further reduces particulates and chlorine. During stage 3, the RO membrane finely reduces chemical contaminants to less than 0.0001 micron, thereby improving the safety of your drinking water. In the 4th and final stage, a granular activated polishing filter (GAC) removes any residual taste that may come from the storage tank.
