reverse osmosis water filter wth permeat pump

Reverse osmosis filters the water through sub-micron filter elements to remove bacteria as well as all organic molecules and even ions from the water. The filter provides for a very high level of filtration to provide essentially sterile great tasting water. The filter is connected to your water supply using the fittings provided, you need at least 50psi water pressure to drive the unit. The permeat pump dramatically cuts down on the water usage, and improves the performance of the system.
