North-Star - Model NSANSSA -Neutralizer Filter

Features And Benefits: Neutralize acid water conditions. Controls the etching and blue-green stains on fixtures, glasses, etc. The neutralizing tank filter contains an acid neutralizing media that slowly dissolves as the water passes through it, raising the pH of the water toward neutral (or 7 on the pH scale.). You must periodically add new media to the tank. The frequency of adding the media depends on the severity of the problem and the water use.
