pH BALANCING FILTER REPLACEMENT: The Watts Premier pH Balancing Ceramic Filter is specifically designed to function as a re-mineralization post-filter for your reverse osmosis system, adding minerals back in to your RO treated water, as well as providing pH balance of the water as needed. HIGHLY EFFECTIVE FILTRATION: This filter is engineered with six distinct layers of filtration: sediment filter for removing silt, sediment, or particulates; pH block mineral filter for a balanced slow release of minerals like calcium and magnesium; pH balancing alkalization for providing a balanced pH and additional mineral elution; coral media for proper pH balancing and improved taste; activated ceramic phase for far-infrared ray release and activation; final sediment filter. EASY INSTALLATION: Specifically designed for the 3/8" tubing to the faucet, this 11" pH balancing ceramic filter includes two 1/4" QC (Quick Change) union fittings for straightforward installation. It is also compatible with all reverse osmosis systems, making it easy to integrate into your existing water filtration setup. QUALITY CONSTRUCTION: Measuring 13" x 7" x 11.5" with 11.5" of media, this durable filter is crafted from high-quality materials for maximum filtration. Filter life may vary based upon local water conditions or use patterns, but we recommend replacing the pH balancing filter every 6 months.
