Parker Sea Recovery HRO pH Neutralizing Filter, 2.5 x 10″, 08251950AS
The product water from the system will be slightly acidic, approximately pH 6.5. This is normal for any Reverse Osmosis System. The pH Neutralizer Filter replaces alkaline, calcium carbonate, which neutralizes the pH of the product water back to a normal of pH 7.5. The life of the neutralizing cartridge depends on the amount of use, amount of product water flowing through it. Replace the element as necessary.
