When choosing an air filter, note the MERV rating to decide which filter best suits you. At Merv Filters LLC, we have a wide selection of MERV 8, MERV 11, MERV 13 air furnace filters. The higher the MERV rating you choose, the better the filter you will receive. Our 18x20x2 furnace air filter of MERV 13 has the capability to remove 96% of airborne particles & bacteria. Electrostatically charged, 100% synthetic graduated density filter that is bonded to the enclosure frame helps prevent dust bypass.
Basically, air furnace filters are directed to be changed every 60-90 days, and especially after 30 days if you have kids/allergy sufferers/pets in your home or you are living in a dust prone area. Also, changing the air filter regularly will save 5% to 15% on your bill in a month.

Important Note: A MERV 13 air filter with size 18x20x2 will actually be delivered to you with a size of 17.5×19.5×1.75 because the actual size of air filters might be a little bit smaller than the nominal or box printed size. So, measure accordingly!
