The 3-stage Hi-S RO 35 and 60 include a Hi-S membrane to remove more phosphate, nitrate, and heavy metals than other membranes. This system removes more silicate from tap water than any membrane available - between 98% and 99%. They also include a sediment pre-filter and a solid carbon block filter. The 4-stage Maxxima 35 combines the features of the Hi-S units with a dual-stage deionization cartridge. The Deluxe Maxxima 35 and Deluxe Maxxima 60 have the features of the Maxxima PLUS a liquid-filled pressure gauge and a TDS monitor to verify membrane function. All units include a 3/4″ garden hose adapter and 6 ft of yellow, blue, and orange tubing. Can be run on any water system, well or city. If your water source gives a psi of less than 60, an RO water pump will help.
