Residential Applications
This Reverse Osmosis system is designed to produce the highest purified water for drinking, cooking, washing your fruits and vegetables.

Reverse Osmosis Method
In simple terms, reverse osmosis works as water is forced across a semi-permeable membrane, leaving contaminants behind that are flushed down the drain. The clean drinking water collects in a holding tank.

Reverse osmosis (RO) is a special type of filtration that uses a semi-permeable, thin membrane with pores small enough (0.0001 micron) to pass pure water through while rejecting larger molecules such as dissolved salts (ions) and other impurities such as bacteria and viruses.

Reverse Osmosis is the best and most effective method to remove up to 99.8% of impurities, including bacteria and viruses. The combination of pre-filters together with the semi-permeable membrane provides excellent quality of clean & pure drinking water. In general, the reverse osmosis system removes solids, chemicals, heavy metals, pesticides, chlorine, arsenic, aluminum, boron, cryptosporidium, fluoride, potassium nitrates, volatile organic compounds VOCs, etc. that may exist in the water.
