It can be purchased as 3 filters pack or 12 filters pack.
Hamilton Beach Replacement Carbon Filter is specially designed to filter traps and neutralizes pet odors.
They keep apartment from smelling like dirty cat litter for months at a time, without putting chemicals into the air, which makes them worth their weight in gold. I find it weird that they come in a 3-pack when the Pet Air Purifier takes 2 at a time, but they work and they’re cheap, so I can overlook that. I just buy 2 three-packs at a time, so I have enough to replace the filters 3 times. – Buyer
