BestAir Advanced Allergen 8500 furnace filters

Summary

• Type: Pleated high-efficiency air filters.

• Rating: MERV 11. This is a mid-to-high performance rating, meaning they are designed to capture not just dust and lint, but also smaller allergens like pet dander, mold spores, and pollen.

• Size: 12×20×1 inch. (This is a slightly less common size compared to the standard 16x25 or 20x20).

• Life Span: Each filter is typically rated for 90 days of use.

• Condition: Since they are unopened and still in the plastic, the filter media is clean and ready for use (exposure to air/humidity over time can degrade unused filters if they aren't sealed).
