Two. The RO200 uses two HL22120 membranes for 200 GPD. The Stealth-RO 100 uses one of the same membrane.

HydroLogic rates the green coconut carbon at about 1,250 gallons in a Stealth-RO and the KDF85/catalytic upgrade at about 2,000 gallons. Clean the pleated sediment filter often and replace it twice a year. Membranes last 6 months to 2 years depending on water.
