Under ideal conditions, the FilmTec membrane removes up to 97% of lead. However, if you don't have a FilmTec membrane, Ametek also makes a special lead-reduction filter which removes 92% of lead from 2,000 gallons of water. The price is $18 for the filter plus $20 for the housing, plus shipping. (No handling fee.)
