Two unopened packets of Moderna brand cut to fit universal filters "active carbon filter absorbs bad odour, cut to size to fit all litter boxes". One filter per packet but the filters are larger than suggested by the photo as each packet contains one large piece of carbon filter folded in half. Purchased from Pets at Home as spares for use in a hooded litter tray with flap door. One of my cats could not get accustomed to the door and with the door removed there wasn't much point in using a filter so these spares were never used.
