Mfr's Description:  " This MAX 50 unit comes with a Non-electric Permeate Pump for bigger/fuller ice cubes which fills faster at the fridge door. Along with a nice steady stream of water from a door dispenser. The MAX 50 has incredible water quality and pressure. Not some old fashioned obsolete e-Bay or big box store Reverse Osmosis system. The Max is very compact, space saving under the sink system. This system takes advantage of the technological improvements made to RO systems and is exactly what any homeowner wants and needs. Great water at up to 50% higher delivery pressure.

Super simple filter changes, no disassembling your system, just plug and play, simply remove the blue dust caps from the end of each filter, and you're ready to go! Theres no need to bother with those old fashioned filters any more. Just plug and play your new replacement filters, no taking apart old fashioned filters to replace the insides. That's right no taking filter housings apart, no o-rings to lose, no muss, and no fuss. Fast, easy, and less costly than that old fashioned system.

This Max 50 GPD system is a 4 stage system much like the Mini Under-Sink RO but this one includes the Permeate Pump for those new refrigerators that require higher PSI into the door dispenser and automatic ice maker.

Stage 1 In-line Carbon filter

Stage 2 In-line Sediment filter

Stage 3 50 GPD FilmTec Membrane

Stage 4 In-line Carbon filter between the storage tank and RO Faucet for better tasting/smelling drinking water

This unit packs a MAX punch for its compact size and great quality of water. We've had nothing but great reviews and compliments on this system. Better water, at better delivery pressure of water when compared to the typical obsolete tap water driven reverse osmosis system.As things improve they get smaller!"
