Aerostar Air Filter

The nominal size is a rounded industry standard for labeling, while the actual dimensions of 15 1/2" x 19 1/2" x 1 3/4" are the precise measurements required for a proper fit in your HVAC unit. Always verify these actual dimensions against your current filter to ensure it seats correctly.

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

No, these are disposable pleated filters designed for single use. They should be replaced every 90 days to maintain optimal airflow and prevent your HVAC system from overworking.

We recommend replacing the filter every 90 days. Depending on your home environment—such as the presence of pets or high dust levels—you may need to check it sooner to ensure it hasn't become clogged.

These filters are designed for standard residential HVAC systems that accommodate a 16x20x2 inch slot. Please confirm your system's specific size requirements and slot depth before purchasing to ensure a secure fit.
