Anti-Allergy Enzyme Filters (2 included) These filters help capture pollen, fine dust, bacteria, and allergens, and include a special enzyme layer that breaks down airborne proteins. In clean-air homes, a single filter may last up to 12 months with regular cleaning. But in homes with pets, smokers, nearby wildfires, high pollen, or dust, more frequent replacement is recommended.
