1X14X20 PLEATED FILTER DELUXE

Filtrete Allergen Defense Air Filter is a 1-Inch pleated HVAC filter designed to help capture common airborne particles while allowing air to flow efficiently through compatible heating and cooling systems. With a 1000 MPR rating and MERV 11 performance, it is designed to attract and capture a wide range of household airborne contaminants, including dust, lint, pollen, smoke, pet dander, and other fine particles. The electrostatically charged filter media helps improve particle capture compared with basic non-electrostatic filters, making it a practical choice for households looking for enhanced everyday air filtration.

The filter uses Filtrete's electrostatic filtration technology, which is designed to attract and capture unwanted airborne particles as air passes through the furnace, air conditioner, or HVAC system. Its pleated construction provides increased surface area for filtration while maintaining airflow through the system, helping reduce the amount of airborne dust and allergens circulating throughout the home. The Allergen Defense filter is particularly well suited for homeowners and families looking for stronger particle filtration than a basic MERV 5 filter, especially in homes with pets, seasonal allergens, or higher levels of household dust.

  The filter is constructed with pleated filter media and a frame designed for routine residential HVAC use. Its MERV 11 rating provides enhanced filtration of smaller airborne particles compared with lower-efficiency filters while still being designed for use in compatible residential heating and cooling equipment. As with any HVAC filter, it is important to select the correct nominal filter size and verify that the filter is compatible with the system's recommended airflow and filtration requirements.

For best performance, Filtrete Allergen Defense Air Filter should generally be replaced about every 90 days, although replacement frequency can vary depending on household conditions, HVAC usage, pets, construction activity, smoking, and the amount of airborne dust and allergens. Homes with pets, multiple occupants, or higher levels of airborne particles may require more frequent filter changes. Replacing the filter regularly helps maintain airflow, supports efficient HVAC operation, and prevents accumulated particles from unnecessarily restricting the system. This makes the Filtrete Allergen Defense MPR 1000 MERV 11 filter a practical choice for homeowners seeking upgraded everyday protection against dust, pollen, pet dander, and other common airborne particles.
