Upflow Acid Neutralizer Filter – In/Out All Purpose Filter (UAN/IOAPF)

Eliminate problem water for good. The UAN/IOAPF is a chemical free upflow acid Neutralizer filter. It can also be used as a In/Out All Purpose filter by loading it with a wide variety of media.



  • Chemical Free Upflow Acid Neutralizer Filters – Eliminate corrosion of metallic pipes and fixtures by dissolving calcium and magnesium into the water, raising pH and neutralizing the acidic water without the use of chemicals.
  • In/Out All Purpose Filters – Can be loaded with a wide variety of media and installed in either upflow or downflow configuration.
  • Multiple Parallel Units Can Be Used for Maximum Flows
  • High Flow Rate – 10/12 gpm
  • Fill Port on In/Out Adapter – Allows addition of media without removing the adapter.
  • Large 1” Connections with Bypass (Optional 1-1/4″ and 1-1/2″ adapters also available)
  • Upflow Design Doesn’t Require Water for Backwashing
  • Multi-Wrap Fiberglass Reinforced Media Tank – Durable fiberglass-wrapped tank liner – doesn’t deteriorate, rust, or corrode.
  • Full One-Inch Riser – One-inch diameter for increased flow rates, which ensures that household demand is adequately met.
  • Media Zone – Water flows up through the media bed, preventing caking and channeling.
  • Easy Determination of Remaining Media – Because the neutralizing media dissolves into the water, it will need to be replenished from time to time. The unshrouded tank allows light to pass through for easy determination of amount of remaining media without taking the filter out of service or removing the In/Out adapter.
