Filter Description

Having trouble with your AC or Furnace shutting down or struggling to keep up with heating or cooling needs? Energy bills costing too much? The New AIRx High Flow filter solves the problem with improved airflow of ordinary pleated filters.
Better airflow means your AC or Furnace doesn't have to work as hard and will heat or cool your home in less time and at a lower energy cost.
With 65% more filter media, High Flow greatly improves air flow while reducing potentially harmful pollutants in your air.
Perfect for all HVAC systems, especially older or sensitive systems.
MERV 11 rating means the filter attracts household allergens like dust, pollen, mold spores, dander, smoke and smog.
Did we mention 65% more pleated media?!
Made with pride in the USA.
