20x25x4 (3 5/8) Pure Baking Soda Odor Deodorizing AC Air Filters Qty 1

Important Note: Almost ALL furnace filters have a different "actual size" than the nominal size printed on the air conditioner filter. It's best if you measure your air filter for the EXACT size and compare it to our "Actual Size" - and then you can be sure your A/C air filter fits! With the 4" and 5" air filters there is a wider variance between the nominal and actual size depending on the manufacturer. If you are replacing a Filtrete 20x25x4 filter in your Honeywell unit you should order our 20x25x5 Pure Baking Soda Honeywell Replacement air filter that measures 19 7/8 x 24 7/8 x 4 3/8 (19.63x24.88x4.38). Nordic Pure 20x25x4 Pure Baking Soda Odor Deodorizing AC Furnace Filters are made of electrostatically charged baking soda media equivalent to a MERV 8 rating. These air condition filters are made with an unscented baking soda media - and a sturdy beverage board frame with a wire mesh backing. Our Pure Baking Soda furnace filters help control and neutralize odors from pets, smoking, cooking and other unwanted scents. Arm yourself with our Pure Baking Soda filter for an odor-fighting bang for your buck! This ac air filter does double duty to ensure household clean, fresh air in your home or office, traps strong smells, and hammers down on allergens, dust, mold spores, pollen and pet dander. Nordic Pure air conditioning filters prohibit the growth of mold and bacteria on the filter itself. The effective life of your AC air filter depends on both the inside and outside conditions in which you live.  It is important to regularly change your furnace air conditioner filters especially during any home improvements for fresh, clean air in your home or office. We recommend that you change your air filter every 3-6 months to maintain maximum efficiency and economy.
