The system includes a high pressure pump and high efficiency carbonator motor, ensuring the water will flow through the sediment and carbon block pre-filters, and RO membranes without a loss of pressure. Reverse osmosis filtration provides fresh, clean and pure tasting water directly from your home faucet. The WH-RO-2000 system arrives to you with everything you need to Protect Every Drop™,.

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-2000 features sediment pre-filtration to reduce physical particulates down to 5 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-2000 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.
