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.

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.

Reverse Osmosis

Reverse Osmosis is the process of forcing water through a semi-permeable membrane, which 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 and Carbon Filtration

Sediment Filtration:
The Sediment Pre-filtration process reduces physical particles, such as sand, rust, silt, soil, and more! This helps extend the life of home appliances, as well as improves your drinking water.

Carbon Filtration:
The Carbon Filtration process has two steps, Carbon Pre-filtration and Carbon Post Filtration.

Carbon Pre-filtration reduces the presence of chlorine taste and odor, as well as the presence of dangerous chemicals in the water.
Carbon Post Filtration is the last step of the filtration process, which allows for the polishing of the water's aesthetic and taste. The water molecules' passes through the semi-permeable membrane; At this point, the water molecules have been freed from contaminates and impurities down to 5 microns during the pre-filtration phases and heavy metals, organics and bacteria have been reduced during the reverse osmosis phase.
