  1. Toxin Absorber (for harmful gaseous air pollution and toxic smoke).
  2. Pet Allergy (for bad smells and allergens from dogs, cats and other pets).
  3. Mold Bacteria (with antibacterial filter to trap germs and allergenic mold spores).

All of these different filter options are here. There’s a filter warning light on the Core 300 to let you know when a filter change is required.
