The WH-RO-1000 provides a whole house reverse osmosis system that can filter at a rate of 1,000 gallons per day. The space saving frame is made of powder-coated aluminum making it resistant to corrosion. The system includes a high pressure pump and solenoid valve to ensure water flows through the sediment and carbon block pre-filters, and RO membrane without losing pressure. Reverse osmosis filtration can give you some of the purest water you can get right from your home faucet. The WH-RO-1000 system comes equipped with everything you need from the housings to the housings frame, flow meters, valves, and pressure gauges.

What is Reverse Osmosis?

Reverse Osmosis is the process of forcing water through a semi-permeable membrane, which all that allows water molecules to pass, but captures water soluble toxins, such as heavy metals, organics, bacteria, and pyrogens. Reverse Osmosis captures a significant percentage of high toxic impurities, such as asbestos, hexavalent chromium, and lead.

Sediment Pre-filtration

The WH-RO-1000 features sediment pre-filtration to reduce physical particulates down to 10 microns from the water source. Contaminants include Sand, Rust, Silt, Soil, and more. The contaminants are captured in the filter cartridge.

Carbon Pre-filtration

The WH-RO-1000 features carbon pre-filtration to reduce the presence of chlorine taste and odor. These foul tastes and odors are are byproduct of standard civic water treatments. The pre-filtration phase also utilizes carbon to reduce dangerous chemicals, down to 5 microns, while the water is allowed to flow unimpeded through the filter.

Don't forget the Tank!

Due to the Reverse Osmosis filtration process, water flow rate is reduced. To effectively utilize this system for whole house filtration, you it must be paired with a water holding tank. On account of the varying water holding capacity needs, the tank must be purchased separately, ensuring you are able to select the size that fits your needs.
