Here are some of the great features of 20x20x5 Honeywell Replacement MERV 12 Pleated Furnace Air Filter Box of 4 - Manufactured by Nordic Pure

20x20x5 Honeywell Replacement, Nordic Pure air filters have an actual size that is a fraction of an inch smaller than the standard size (also known as "nominal size"). The size printed on your air filter may NOT be the Actual Size. With the 4" and 5" air filters there is a wider variance between the nominal size and actual size for the different manufacturers. Because of this, the air filter you are replacing could be called a 20x20x4 and really be the same as our 20x20x5. This is why we ask you to measure your air filter so you aren't surprised if the air filter doesn't fit! You may be able to use our standard 20x20x4. Just check the "Actual Size" before ordering. We manufacture high efficiency pleated furnace air filters for your heating and air conditioning systems. We can make most odd sized custom HVAC air filters for low cost and fast free delivery. Our non-woven synthetic air filter media will not support the growth of mold or bacteria, keeping your home healthier. Our air filters use permanently charged electrostatic material that helps dust cling to the air filter. This helps protect your family from allergy causing pollen, fine dust, tobacco and cooking smoke, airborne plant spores, bacteria, and some viruses. Changing your air filter is the first step in insuring your HVAC system runs at its optimal level this season. Generally, you should change your 1 inch & 2 inch air filters every 30, 60, or 90 days. The 4, 5 & 6 inch air filters should be changed every 3 to 6 months. Standard air filters generally ship within 2-10 business days. Actual shipping time will depend on delivery address. We have been manufacturing air filters since 1960, and because HVAC systems have advanced through the years, we have trekked the same course and improved our air filters too. Try them, and we are certain you'll be pleased with our great air filters.
