North Star Water Neutralizer Filter
Used to treat acid water with a pH of 6.0 to 6.8.

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.

Models NSANSSA 10" Filter (includes mineral, gravel and sand)
Model NSAPFXLA 12" 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.
• New Easy-To-Use 24-Volt Controller - Solid State Control with 24 Volt transformer included, provides precise control of all functions
• Full 1-Inch Diameter Riser Tube for increased flow rate
• Multi-Wrap™ Fiberglass Reinforced Resin Tank
• Multi-Cycle Valve with easy-clamp ring and patented Teflon® discs
• Includes Bypass Valve and Installation Kit
• Warranty:
  • 1 year on complete unit
  • 3 years on electonic control and control valve body
  • 10 years on mineral tank (excluding mineral)
