Under Sink Reverse Osmosis

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 final 4th stage, a granular activated polishing filter (GAC) removes any residual taste that may come from the storage tank. To maintain optimum water filtration system performance, replace the filters every six months and replace the RO membrane every two years. This water filtration system features a compact, bracket-mounted design with that includes everything you need for quick and easy installation.

Drink cleaner, refreshing water with the PUR® 3-Stage Quick-Connect Reverse Osmosis (RO) Water Filtration System. Conveniently install this 3-stage RO water filter system under your sink to deliver more PUR®ified water through a secondary air gap faucet. Make an environmental choice and avoid bottled water, choosing this water filtration system that is NSF certified to reduce at least 15 unwanted contaminants including lead, cysts, TDS and heavy metals. During stage 1, the 5 micron carbon block filter reduces particulates and chlorine. In stage 2, the RO membrane further filters to less than 0.0001 micron, thereby reducing chemical contaminants and improving the safety of your drinking water. In the final 3rd stage, a secondary carbon block filter removes any residual taste that may come from the storage tank. This quick-connect design makes replacing the filters a breeze with a simple flip of a switch and twist of the wrist. For best water filtration system maintenance, replace the carbon block filters every six months and the RO membrane every two years. This water filtration system features a compact, bracket-mounted space-saving design with everything you need for quick and easy installation.

This 4-stage under sink RO water filter system delivers more PUR®ified 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 at least 15 unwanted contaminants including lead, cysts, TDS and heavy metals. During stage 1, the 5 micron sediment filter reduces rust, sand and dirt.  In stage 2, water flows through a 5 micron carbon block filter to further reduce particulates, as well as chlorine. In stage 3, the RO membrane further filters the water to less than 0.0001 micron, thereby reducing chemical contaminants and improving the safety of your drinking water. During the final 4th stage, a secondary carbon block filter removes any residual taste that may come from the storage tank. The no hassle quick-connect design makes replacing the filters easy with a simple flip of a switch and twist of the wrist. For optimum water filtration system maintenance, replace the sediment and carbon block filters every six months and the RO membrane every two years. This water filtration system features a compact, space-saving design that includes everything you need to get started with the quick and easy installation.

For the ultimate cleaner and refreshing water, install the PUR® 5-Stage Quick-Connect Reverse Osmosis (RO) Water Filtration System. Conveniently install this 5-stage RO water filter system under your sink to deliver more PUR®ified 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, as well as chlorine.  Stage 3 utilizes a secondary carbon block filter to further reduce chlorine and help maximize the RO membrane life. During stage 4, the RO membrane filters chemical contaminants to less than 0.0001 micron, thereby improving the safety of your drinking water. In the final 5th stage, a granular activated polishing filter (GAC) removes any residual taste that may come from the storage tank to enhance the taste of the water. The quick-connect filter replacement design is fast and simple. To keep this water filtration system operating in tip-top shape, simply replace the filters every six months and the RO membrane every two years.
