8 Components. One Complete System.
Every PWT RO System is built around a reliable single-manifold design that houses four separate filter technologies in a compact, space-saving footprint under your kitchen sink.
Sediment Filters
Screens out sediment, sand, silt, and particles. Multiple micron size options available to match your specific water supply.
Carbon Filters
Reduces elements that cause water to taste and smell unpleasant — including chlorine taste and odor — before water reaches the RO membrane.
Reverse Osmosis Membrane
Thin Film Composite membrane reduces 95% of TDS and certified contaminants. Available in 50 and 75 GPD capacity to match your household's demand.
Specialty Filters
pH boosters, remineralizers, and GAC polishing filters optimize taste and adjust to your local water conditions for the best possible drinking water.
Manifold Assembly
Single manifold houses four separate filter technologies in a unique, space-saving design — ensuring reliability and easy access for filter changes.
Shutoff Valve
Automatically opens and closes the water supply to and from the reservoir tank — maintaining proper pressure and protecting the membrane.
Reservoir Tank
Durable, high-quality powder-coated steel tank ensures a plentiful supply of filtered water is always ready at your tap. Various sizes available.
Designer Faucet
Multiple styles and finishes available to match your kitchen. Dedicated RO faucet installs cleanly on your sink for easy access to purified water.
Interchangeable Filters for Your Water
The Quick Change design supports a full range of filter cartridges — mix and match to address your specific water conditions. All use the same 1/4" Quick Connect port.
Sediment Filter
Screens out sediment and particles before they reach the carbon and RO stages. Protects downstream filters and extends system life.
Carbon Block Filter
Reduces chlorine taste and odor, protecting the RO membrane and improving the quality of filtered water.
RO Membrane (50 GPD)
Thin Film Composite membrane — the heart of the system. Removes 95% of TDS including lead, PFOA/PFOS, arsenic, fluoride, and heavy metals.
GAC Carbon Filter
Post-membrane polishing filter removes any remaining taste and odor for the crispest, cleanest final product water.
pH Booster Filter
Raises the pH of purified water and remineralizes it — adding beneficial minerals back for a smooth, alkaline taste.
Carbon Block — 1 Mic
1-micron carbon block for fine particulate reduction alongside chlorine, taste and odor removal. Ideal for high-demand applications.
