Nordic Pure 20x20x4 (Actual Size: 19 1/2 x 19 1/2 x 3 5/8) Pure Carbon Pleated Odor Reduction Merv 8 Furnace Filter 1 Pack

Product Description

Important Note: Almost ALL furnace filters have a different "actual size" than the nominal size printed on the air filter. It's best if you measure your air filter for the EXACT size and compare it to our "Actual Size". 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 4 3/8 depth 20x20x4 filter in your Honeywell unit you should order our 20x20x5 Honeywell Replacement Pure Carbon Pleated Odor Reduction air filter that measures 19 5/8 x 19 7/8 x 4 3/8 (19.63x19.88x4.38). Nordic Pure 20x20x4 Pure Carbon Pleated Odor Reduction Air Filters are made with a durable non-woven polyester base media infused with naturally derived charcoal, created to eliminate odors in your office or home. Our pleated design provides three times as much carbon media per A/C filter but maintains excellent air flow. Nordic Pure pleated air filters are manufactured using a heavy duty, moisture resistant beverage board frame. There is a metal mesh support grid bonded to the pleats for extra support. The activated carbon, odor eliminator Pure Carbon AC furnace filters can be used in residents as a stand-alone filter. They can also be used as a pre-filter in high-efficiency commercial HVAC units. They remove levels of Volatile Organic Compounds (VOCs) such as chemicals from household cleaning products. For maximum odor control, we recommend that you replace your air conditioning filter every 3-6 months.
