Customers Who Bought This Item Also Bought

The Filtrete 4" Ultra Allergen Reduction Deep Pleat Air Filter - 1550 MPR, 4-Pack replacement air filter uses deeper pleats than comparable 1-inch filters which results in a higher surface area and better spread of dirt and debris. Compare this to smaller filters that are more likely to lose air flow as the filter media loads. With Filtrete's 3-in-1 technology you get higher flow rates with a long lasting tightly woven fibrous filter media. Replacing air filters regularly can help diminish the amount of dust, pet dander, mold, pollen, and smoke, to name a few, found in the air and settled on surfaces. 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.
