The 3M Filtrete NDP03-4S-2P-2 Replacement Air Filter - 20x25x4 extends the depth of the filter media from the more common 1-inch size to 4-inches to provide significantly greater surface area and containment reduction. With the larger filter you still enjoy the benefits of Filtrete's 3-in-1 technology that combines higher flows rates with a long lasting tightly woven fibrous filter media. A greater surface area comes with several benefits, namely a greater spread of airborne pollutants that translates to fewer pressure drops and higher flow rates. With your indoor air potentially being crowded with dust, pet dander, mold, pollen, smoke, just to name the most common contaminants, your air conditioning system is prime real estate for installing a new air filter. Similar to the heart, when everything is up and running the air in your home will at some point find its way through your ventilation system. With a 4-inch air filter you will be moving high volumes of air across the filter media where more contaminants can become trapped. As these pollutants stick to the filter media airflow will remain strong for long after installation. For optimal performance, filter should be checked monthly and replaced ever 3 to 6 months depending on air quality.
