The AquaRain Gravity Water Filter is made of stamped stainless steel. That means there are NO welds to contaminate your filtered water! Depending on the condition of the input water, it will filter 30,000 to 60,000 gallons before the filter elements need to be replaced. Note its filtering pore-size (smallest in the industry):
# 0.2 micron absolute pore size. # Zero moving parts. # Cleanable ceramic filter element (replaceable and cleanable 200x by hand). # Silver-impregnated ceramic to prevent bacterial growth. # Granular activated carbon filtration to remove chemical and organic compounds and improve taste. (Carbon is contained within the ceramic core.) # A filtering capacity of up to 32 gallons a day. # Stainless steel construction. # Handles on filtering section for easy lifting. # Exclusive "drip lip" to prevent contamination of filtered water. Double filtration, both ceramic and carbon in each element . . . and it filters enough water for 6 people a day (4 element model). It's been manufactured to meet ANSI/NSF standards, the toughest there are. IBR (Inter Basic Resources) 4/4/97 test report states that the AquaRain filter, at absolute 0.2 microns has 99.99 log 5.92 efficiency. I failed trig in high school, but I'm told that means it has 99.99992 filtering efficiency at 0.2 microns! (Our nearest competitor, the British Berkefeld, certifies at only 0.9 microns with only 99.99 filtering efficiency.)
