This 27oz Biological Bottle, made with BPA free plastic, has a 2-Stage Filtering Process. Each filter provides filtration in specific areas, and together they make up the best and most complete filtration available.
Stage 1: The Level 2 carbon composite filter removes 90% of the chlorine, lead, mercury, copper, VOCs, and PCBs at a flow rate of 10ml/sec. This carbon composite filter functions as a pre-filter reducing small particulate matter extending the life of the Sub-Micron Biological Filter. The carbon composite filter also removes the taste of a disinfectant that may be added, like chlorine, if viral contamination is suspected.
Stage 2: The Sub-Micron Biological Filter provides for the removal of bacteria, cysts, cryptosporidium, and protozoa from contaminated water. In independent testing conducted in accordance with EPA protocol, the Sub-Micron Biological Filter removed over 99.99% of cysts and 99.9999% bacteria at EPA protocol concentrations. This bottle has even been certified to remove anthrax spores!
This product is filled with water and squeezed to pass the water through the dual filter elements. This bottle will treat 80 gallons or 480 bottles of drinking water.
