Berkey Gravity Filter System Replacement Filter for Black Purification Filters (BB9-2) & Fluoride Filters (PF-2) Combo Pack - Includes 2 Black Filters and 2 Fluoride Filters
- High-efficiency filtration: Efficiently reduces chlorine, fluoride, heavy metals, taste and odor, sediments, large particles and other harmful substances. Clean and healthy water can be enjoyed outdoors at any time. Please note that TDS level does not fully indicate the quality of the water and our filters DOES NOT lower TDS value.
- Excellent reduction performance: Black filter is made from coconut activated carbon block to achieve high adsorption rate of chlorine and to ensure harmful substances will not leach back into water. Fluoride filter has been upgraded and now uses both granular activated carbon and activated alumina as filter media, which significantly improves the water taste.
- Longer service life: To achieve optimum performance, we recommend you replace the black filters every 6,000 gallons per pair and replace the fluoride filters every 1,000 gallons per pair, which will vary based on water conditions. The package includes two black filters, two fluoride filters and two priming buttons.
- Compatible models: Replacement for the original brand of BB9-2 black purification elements and PF-2 fluoride replacement filter.
