UNF Neutralizing Filters
Neutralizes and Raises pH of Acidic Water
Certified for Low pH Adjustment
The UNF upflow NRV Neutralizing Filter features a specialized media that raises the pH of acidic water, effectively neutralizing its corrosive properties. By increasing the pH, it not only protects pipes, plumbing fixtures, and appliances but also enhances the oxidation of iron and manganese, enabling the use of an iron filter. Over time, replenishing the media may be necessary for optimal performance.
