Aerostar Air Filter

For optimal performance and air quality, we recommend replacing your filter every 60 to 90 days. If you have pets or live in a particularly dusty environment, you may need to change it more frequently to maintain airflow.

The MERV rating indicates the filter's ability to capture particles. A MERV 8 filter is excellent for general dust and pollen, while MERV 11 and 13 offer higher filtration levels, capturing smaller particles like smoke, bacteria, and virus carriers. Choose a higher rating if you have specific concerns about indoor air quality or allergies.

No, this is a disposable, single-use filter made from synthetic material. Once it has reached the end of its 90-day lifespan, it should be discarded and replaced with a new one to ensure your HVAC system continues to run efficiently.

Check the dimensions printed on your current filter or look at your HVAC system's manual for the required nominal size. This filter has an actual size of 11 3/4" x 23 3/4" x 3/4", so ensure your system's filter slot matches these specifications for a snug, secure fit.

No, this filter relies on its pleated synthetic media design to physically capture particles rather than an electrostatic charge. The pleated construction increases the surface area, allowing it to trap dust and debris effectively as air passes through.
