ABSTRACT:
A water filtering canister unit having self-contained reverse osmosis and activated carbon filtering systems which are adapted for connection onto the water tap in a home, apartment or office. The canister unit includes a housing defining an inner chamber in which a cylindrical reverse osmosis membrane is mounted. Water molecules which pass through the membrane continue through a capsule containing a body of activated carbon particles and thence outwardly through a discharge conduit. Dissolved salts and minerals as well as particulate matter rejected by the membrane are discharged in brine water at a controlled rate through a lower end cap on the housing.
