Reverse Osmosis

Reverse osmosis is a water filtration method that is used by passing water through a semipermeable membrane to reduce a significant amount of contaminants and larger particles from your water. This purified water is held in a pressurized tank so it can be delivered on demand. Reverse osmosis is a very practical method of reducing many contaminants since the membrane rejects most particles larger than the water molecules it is designed to let pass through. These rejected contaminants are then redirected to the waste water drain and the filtered water is stored for use. Tier1 carries and assortment of RO systems to ensure you will find the system that fits your needs. Tier1 is ready to protect every drop.
