Aerostar Filtre à air

The nominal size of 18x24x2 inches is the industry-standard label used for shopping, while the actual size of 17 3/8" x 23 3/8" x 1 3/4" is the precise measurement of the filter frame. Always measure your current filter or filter slot to ensure the actual dimensions will fit your specific HVAC system.

For optimal performance and to keep your HVAC system running efficiently, you should replace this filter every 60 to 90 days. If you have pets or live in a dusty environment, you may want to check it closer to the 60-day mark.

These ratings indicate the filter's efficiency at capturing airborne particles. An MPR 600 / FPR 5 rating is designed to trap common household contaminants like dust, pollen, and bacteria in the 3-10 micron range, providing a solid balance between filtration and airflow.

While this filter effectively captures common particles like dust and pollen, it is a standard capacity filter. If you suffer from severe allergies or asthma, you might consider a higher-rated filter designed to capture smaller, microscopic particles.

This filter is designed to balance effective particle capture with proper airflow. Because it is a standard capacity filter, it should not restrict airflow in most compatible home or office HVAC systems, provided it is replaced regularly.
