Best Home Master Under Sink Countertop Filtration in 2026

Reduced Water Waste & TDS Creep | Built in non-electric permeate pump reduces TDS creep and water waste up to 80%, increases water production up to 50%. No electricity required.

Faster Flow Rate | Included Fast Flo RO! Kit has larger fittings and tubing provide twice the flow of traditional RO systems.

Modular design | Easy to upgrade and service. Filter changes once per year or 2000 gallons with no wrenches required.

In the box: assembled purification unit with filters and DOW RO membrane (0.0001 micron, 50 gpd), storage tank, 3/8 in. feed water adapter with shut off, chrome faucet and adapter, drain saddle. DIMENSIONS: Purification cluster - 16” high x 15” wide x 5” deep, Reserve tank - 15” high x 11” diameter.

Catalytic Carbon | Home Master catalytic carbon outperforms ordinary activated carbon in removing stubborn chloramines, chlorine and other chemicals.

Dedicated Sediment Filter | 5-micron depth sediment filter prolongs the life of down-stream filters, ensuring highest possible water pressure and reduced water waste.

Well or City Water: IRON prefilter protects RO membrane from iron up to 1ppm; permeate pump reduces water waste in low pressure applications

Faster flow rate; twice as fast compared to traditional RO systems; long lasting easy-to-change filters; only once a year or 3,000 gallons

Excellent purification -- removes up to 95 percent of sediment, chloramines, chlorine, chemicals, heavy metals, and other contaminants

Oversize filters improve flow rate and reduce maintenance frequency

Portable - compact unit travels well
