Aerostar Pleated Air Filter

For optimal performance and to prevent airflow restriction, we recommend replacing these filters every 90 days. If you have pets, allergies, or live in a dusty environment, you may want to check them every 60 days.

While MERV 13 filters are denser than lower-rated options, the Aerostar pleated design is engineered to maintain proper airflow. However, if your HVAC system is older or has a weak blower motor, it is a good idea to monitor your system's performance after installation.

The nominal size (16 x 20 x 1) is the industry-standard label used for shopping, while the actual size (15.75 x 19.75 x 0.75) is the precise measurement of the filter. Always measure your current filter or your filter slot to ensure the actual dimensions match your system's requirements.

Yes. The electrostatic charge acts like a magnet, attracting and holding onto microscopic particles like dust, pollen, and pet dander that might otherwise pass through standard fiberglass filters. This makes the filter significantly more effective at cleaning your indoor air.

With a MERV 13 rating, these filters are capable of capturing a high percentage of airborne particles, including bacteria and virus-carrying droplets. While they improve indoor air quality significantly, they should be used as part of a broader strategy for maintaining a healthy home environment.
