Specifications:

• Whole House or Under-Sink Fluoride Filter 4.5 x 20" big blue style
• Includes filter housing with 1" pipe thread, Aries Fluoride Filter Cartridge: 4.5 x 20", mounting bracket and filter change wrench
• These filter elements are designed to reduce fluorides in drinking water to below 0.5 ppm.
• Change every 13,000 gallons depending on local water chemistry
• They are with constructed with materials which are FDA approved.
• The 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 13,000 ppm F+. For example if your water has 1.0 PPM of fluoride in it, the filter can be expected last approximately 13,000 gallons
• Performance will be degraded by flow rates in excess of 4.0 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.
