The Pentair FreshPoint GRO-350 Reverse Osmosis (RO) System is designed to transform ordinary tap water into clearer, more refreshing water with the turn of your tap by reducing a broad range of impurities found in your home water. That means less lead, arsenic, fluoride, and less foul tastes and odors from chlorine – just to name a few. And, the Pentair FreshPoint GRO produces less water waste than other reverse osmosis systems in the market.
When you can enjoy refreshing, high quality water right from your home, there’s no need to waste money on expensive plastic bottled water or bulky pitchers taking up too much space in the refrigerator. The Pentair FreshPoint GRO-350 Reverse Osmosis System can provide excellent water in just 3 simple steps. This system features patented Diamond Flow technology, which combines two filtration technologies into one to give you cleaner, high quality, chug-worthy water. And, with Green RO technology, the FreshPoint GRO-350 produces less water waste, leaving you – and your water – with a clear conscience. Other features include:
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.
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.
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.

The air-gap side faucet (included) must be used with the GRO-550 systems.
No, the cartridges are only designed for cold water filtration.
Cartridges should be replaced every year (or 675 gallons) for pre/post filtration cartridges and every 18 months for the membrane. A couple of signs that a cartridge needs to be replaced are reduction in flow or chlorine smell/taste (for monitored systems, when light turns red while pushing the button on top of the system, it is time to change the membrane)
Yes, an additional water line can be run to the ice maker to give cleaner, clearer ice! See the manual for optional installation instructions

The Pentair FreshPoint 5-Stage Reverse Osmosis System is our most comprehensive under counter filtration system, using 5 unique steps to reduce a broad range of contaminants and impurities found in your home water, and polishes it off to give you better tasting water.
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.
Beyond taste and odor, the volatile chemical nature of chlorine means it can react and form potentially harmful byproducts. But, how much chlorine is ‘safe’?
The benefits of reverse osmosis water systems can transform your drinking water, but exactly is reverse osmosis and how does it work?
