Benefits of a Drinking Water Filter

When you can enjoy refreshing, high quality water right from your home, there’s no need to waste money on expensive plastic bottled water. Enjoy the peace of mind of a FreshPoint 5-Stage Under Counter Reverse Osmosis System. This system features patented Diamond Flow technology, which combines two filtration technologies in one. And, with Green RO technology, the FreshPoint GRO-575 produces less water waste, leaving you – and your water – with a clear conscience. Other features include:

  • Comes ready to install with a dedicated air-gap faucet
  • Air-gap faucet prevents ‘bad’ water from backing up into ‘good’ water if there is a clog in the drain
  • Polishes water to give it a better taste
  • Storage tank gives you ready-to-drink water on-demand
  • High-efficiency membrane technology delivers up to 75 gallons per day
  • Effortless click-in installation that saves you time
  • Color-coded cartridges make filter change-outs simple and hassle-free
  • Less water waste than other RO systems in the market
  • Uses no harmful chemical additives to give you a higher quality of water

How it works

4 stage system

Chlorine Taste & Odor Reduction

Tap water passes through Pentair’s patented Diamond Flow technology – a combination of two technologies in one: a carbon block designed to reduce taste and odors, and a poly spun shell wrapped around the carbon block to reduce sediment and help protect the life of the carbon block.

Contaminant and Impurities Reduction

Water then moves through the reverse osmosis membrane which reduces a broader range of contaminants and impurities found in your home water. The membrane separates the water containing contaminants and sends it down the drain while pushing the more pure water in to the next stage. Pentair’s patented Green RO (GRO) membrane reduces the amount of water waste compared to standard members in the market.

Twin Carbon Block Protection

Tap water passes through a set of twin carbon blocks with lead reduction media. This block reduces chlorine taste & odor, lead, cysts, atrazine, lindane and sediment

Better Tasting Water

Water then passes through the final stage, a granular activated carbon (GAC) filter, which reduces remaining contaminants while “polishing” the water to give you better tasting water. This water is then stored in a 4.4 gallon storage tank that hold the water until you are ready for clearer, better tasting water.

  • Air Gap Side Faucet
  • Storage Tank
  • Installation Kit
  • Owner’s Manual / Installation Guide

Installation Information

Recommended Installation: DIY + or Professional Installation

  • Choose a mounting location suitable to support the full weight of the system when operating.
  • Install vertically with the cartridge hanging down.
  • System may be installed with cartridge flush to the baseboard if desired as the mechanical assist level pushes cartridges straight out.

Operation Tips

  • Replace pre/post filters every year
  • Replace RO membrane every 18 months
  • Place replacement cartridges in proper sequence utilizing color-coded shapes
  • System designed with integrated check valves so cold water line does not need to be shut-off to perform cartridge change-outs.

Lead is harmful even in small doses, as the EPA attests. The EPA has set the maximum contaminant level goal for lead in drinking water at zero. Learn about how lead gets into your water and which products are recommended to reduce its effects.
