Key item features

  • Universal HVAC Compatibility: These 18x24x1 replacement air filters (actual size: 17.38" x 23.38" x 0.75") are designed for furnaces, air conditioners, or heat pumps, enhancing system efficiency and supporting a healthy lifestyle.

This product was recommended by our AC maintenance company. Not only is it a great product that works better than the filtretes we were using but the cost is good as well.
