Water Neutralizer

Used to treat acid water with a pH of 6.0 to 6.8

North Star Water Neutralizer Filter

The neutralizing tank filter contains an acid neutralizing compound that slowly dissolves as the water passes through it, raising the pH of the water toward neutral (or 7 on the pH scale). This controls the etching and blue-green stains on fixtures, glasses, etc.

 North Star Filter
Models NSANSSA 10″ Acid Neutralizer Filter (includes mineral, gravel and sand) Model NSAPFXLA 12″ All-purpose Filter (does not include mineral, gravel and sand)

Features and Benefits Include:

  • Filled With A Bed Of Neutralite/Magnesium Oxide Mineral – As acid water passes through the filter, some of the mineral dissolves to raise the pH and neutralize the acid. Since the neutralizing compound dissolves in the water to correct the problem, you must periodically add new compound to the tank. The frequency of adding the compound depends on the severity of the problem and the water use.
