If you purchased the 1.5 Gallon Stainless Steel Kitchen Composter form either "Norpro" or "RSVP" the proper replacement filters, for the best price are the 2-pak "BigKitchen - Large 2 Gallon" ASIN: B002AB0N5Y for $8.95.The Norpro 84F (ASIN: B003PD9HBC) and 94F from "Chef's Tools" (ASIN: B0042YYCPY) from "Chef's Pal" are slightly smaller and more expensive for a 1-pak. The Norpro 93F will never fit the 1.5 gallon composter. Also, the images can not be relied upon.
