Aerostar Air Filter

While the nominal size is 16x24x2 inches, the actual dimensions are 15 3/8" x 23 3/8" x 1 3/4". Always measure your current filter or the filter slot in your HVAC unit to ensure these exact dimensions match before purchasing.

The MERV rating indicates the filter's efficiency at capturing particles. A MERV 8 filter is standard for basic dust and pollen, while MERV 11 and 13 offer higher filtration capabilities, capturing smaller particles like bacteria and smoke, though they may require your HVAC system to work slightly harder due to increased airflow resistance.

We recommend replacing the filter every 60 to 90 days. If you have pets, suffer from allergies, or live in a particularly dusty environment, you may want to change it closer to the 60-day mark to maintain optimal airflow and air quality.

Yes, this filter corresponds to an FPR 5 rating and an MPR 600 rating. These are helpful cross-references if you are used to shopping by those specific metrics.

Generally, yes. Higher MERV ratings mean a denser filter media, which can increase resistance to airflow. If your HVAC system is older or not designed for high-efficiency filtration, a MERV 8 is often the safest choice to ensure your system continues to run efficiently without strain.
