PRODUCT FAQ

  1. What makes the Filtrete™ Allergen Defense Air Filter different from other air filters on the market?

    The Filtrete™ Allergen Defense Air Filter, 1000 MPR, AL42-4 is designed with exclusive 3-in-1 technology that captures large airborne particles like pollen and dust. It also attracts and captures microscopic allergens like pet dander and mold spores while maintaining airflow.

  2. How often should I replace the Filtrete™ Allergen Defense Air Filter for optimal performance?

    We recommend replacing your filter every 90 days to ensure it continues effectively capturing airborne particles and allergens. However, if you have pets or allergies, you may need to replace it more frequently.

  3. Will the Filtrete™ Allergen Defense Air Filter help reduce odors in my home in addition to filtering out allergens?

    While primarily designed for trapping allergens, the Filtrete™ Allergen Defense Air Filter can also help reduce common household odors such as those from cooking, pets, and smoke. For stronger odor control, consider using an additional air purifying system along with your filter.
