Aerostar pleated air filters for furnaces, air conditioners and HVAC systems, in many standard sizes.

Ratings: MERV 6 for basic dust and lint, MERV 8 for everyday filtration, MERV 11 for allergens and pet dander, and MERV 13 for finer particles. Check that your system can handle the airflow of a higher MERV rating before moving up.

Sizes: mostly 1-inch filters, from 12x12x1 up to 20x30x1, including 16.5x21.5x1 and 19.875x21.5x1, plus 20x25x4 filters.

Pack sizes: 2, 4, 6 and 12 filters. Find the nominal size (length x width x thickness) printed on the edge of your current filter and choose the same size.
