Specifications:

• Aquacera Filter Cartridge: A-2 BB Fluoride 4.5 x 10""; fits standard big blue housings.
• These filter elements are designed to reduce fluorides in drinking water to below 0.5 ppm.
• They are with constructed with materials which are FDA approved.
• The A-2 filter element uses activated alumina that has been especially prepared for the reduction of fluorides in drinking water.
• Laboratory tests show that this preparation will improve the capability of the filter to reduce the fluoride levels from 10 ppm F+ to below 0.2 ppm F+.
• Expected capacity is for removal of 20,000 ppm F+.
• Performance will be degraded by flow rates in excess of 2.0 gpm, high pH or high bicarbonate supply water.
• If the supply water tests above 100 ppm of bicarbonate, the fluoride reduction will be degraded to less than 50%; if the supply is over 200 ppm, the reduction efficiency is less than 75% of normal.
