Purolator Key Pleat Extended Surface Pleated Air Filter, MERV 8, 16 x 25 x 1 (Pack of 2)

Purolator Key Pleat Air Filter, supplied by Sterling Seal & Supply, is a standard capacity pleated filter available in 1", 2", or 4" depths and several standard face sizes to accommodate most system requirements. The Key Pleat MERV 8 filter features a seven-strap die cut located on the air-leaving side, providing additional strength and durability. The inside of the die-cut frame is coated with adhesive to ensure a solid bond at all points of contact with the media pack, which is sealed inside the frame. The pleat tips are bonded to the stabilizers and diagonal support members.

When looking to replace your air filter, there are two different sizes to understand: "Actual Size" and "Nominal Size." The Actual Size consists of the true dimensions of your filter, including a fraction of an inch, such as 19 1/2 x 19 1/2 x 3/4. However, filters are not sold by their actual dimensions; instead, a rounded-up number is used, referred to as the "Nominal Size." 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 buying replacement filters.

Heating and cooling can account for more than 50% of your home energy use. By cleaning or replacing air filters regularly, you can improve the performance of your system and reduce energy costs, saving up to $75 per year. A dirty air filter reduces the air quality in your home, which can aggravate allergies and asthma, particularly in children. Changing your filter is important for your family's health. A dirty air filter also causes your heating and air-conditioning systems and ducts to get dirty faster.

The Purolator Key Pleat Air Filter, KP-5251074025x2, is a Mechanical MERV8 Filter with low initial resistance for energy savings. It is Quality Engineered, Consistently Produced, made of 100% synthetic fibers, and has been made in the USA for over 30 years. The single-piece beverage board die-cut frame provides structural integrity unlike any self-supported filter available today. The pleats hold together even when wet, with no delaminating, excessive buckling, or collapsing. The filter can endure impact and deformation and return to its original shape. The Actual Size is 15-1/2" Width x 24-1/2" Height x 3/4" Thick, and the Nominal Size is 16" Width x 25" Height x 1" Thick.
