The Purolator Key Pleat Air Filter, supplied by Sterling Seal & Supply, is a standard capacity pleated filter available in various depths and face sizes to accommodate most system requirements. The filter features a seven-strap die cut on the air-leaving side, providing additional strength and durability. The die cut frame is coated with adhesive to ensure a solid bond between the media pack and the frame, and the pack is sealed inside the frame with the pleat tips bonded to the stabilizers and diagonal support members.

When replacing your air filter, it's important to understand the difference between the "Actual Size" and the "Nominal Size." The Actual Size refers to the true dimensions of the filter, including fractions of an inch, while the Nominal Size is a rounded-up number used to label the filter packages. For example, a filter with Actual Dimensions of "19 1/2 x 19 1/2 x 3/4" will have a Nominal Size of "20 x 20 x 1," which is the measurement to look for when purchasing replacement filters.

Regularly cleaning or replacing your air filters can significantly improve the performance of your heating and cooling system, reducing energy costs by up to $75 per year. A dirty air filter can also negatively impact the air quality in your home, aggravating allergies and asthma, particularly in children. Therefore, it's recommended to check your air filters every month and change them as needed.

The Purolator Key Pleat Air Filter is a MERV 8 filter with a low initial resistance for energy savings. It is made of 100% synthetic fibers and has been manufactured in the USA for over 30 years. The single-piece beverage board die cut frame provides structural integrity, and the pleats are designed to hold together even when wet, preventing delamination, excessive buckling, or collapsing. The filter can endure impact and deformation while maintaining its original shape.
