Furnace Air Filters, Purolator Merv 8 Key Pleat, 4 inch deep sizes (2-Packs)

All 4" Deep sizes in this listing.  Purolator Key Pleat ASHRAE 52.2-2 Rated Air Filters, supplied by Sterling Seal & Supply are standard capacity pleated filters, available in 1", 2" or 4" depths and several standard face sizes to accommodate most system requirements. A seven-strap die cut is located on the air-leaving side of the Key Pleat MERV 8 providing additional strength and durability to each filter. 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. The pack is sealed inside the frame and pleat tips are bonded to the stabilizers and diagonal support members. ** Facts about Home & Business Air Filters, Allergies, and Filter Quality ** When looking to replace your air filter, there are typically two different sizes you need to understand, "Actual Size and Nominal Size". First: The Actual Size consists of the true dimensions of your filter when measuring length, width and Depth (thickness). These dimensions typically include a fraction of an inch within them. For example: 19 1/2 x 19 1/2 x 3/4 Second: What you might not realize is that filters are not sold by their actual dimensions. Instead a rounded up number is used to label filter packages. This measurement is referred to as the "Nominal Size". Third: So 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", and that will be the measurement to look for when buying your replacement filters. ** Check your air filters every month ** 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.  A dirty air filter reduces the air quality in your home. Poor home air quality can aggravate allergies and asthma, particularly children's allergies. Change your filter for your family's health.
