Product Description As the push for RO home filtration continues, there is also a growing trend to have some minerals added back in to the water, while keeping in mind the need to ensure certain harmful materials are out. After many years of research, Watts Premier launched our in-line pH balancing, far-infrared, re-mineralization filter. The Watts Premier pH Balancing Ceramic Filter functions 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. 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. Specifically designed for the 1/4" tubing to the faucet, this 9-inch 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. Measuring 13" x 7" x 6.6" with 9.5" 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. From the Manufacturer With the increase in water quality concerns homeowners continue to turn to reverse osmosis as a solution to their concerns. Reverse osmosis provides unparalleled consistency in delivering the highest quality water through its multi layered level of filtration, with the RO membrane filtering down to 1/10,000 of a micron. This is why most bottle water companies turn to RO technology as a means to achieve reliable, consistent product in the marketplace no matter the source water. As this push for RO home filtration continues, there is also a growing trend to have some minerals added back in to the water, while keeping in mind the need to ensure contaminants such as arsenic, lead, cysts and others are out. After many years of research, Premier now launches this in line pH balancing, far-infrared, Re-mineralization filter. This filter consists of six separate layers of filtration in order to provide balanced, re-mineralized water to you and your family.
