Toddy?s unique brand of cold brew filtration extracts all the natural and delicious flavors of coffee and tea, leaving behind the bitter acids and oils attached to their warm brew counterparts. In that sense, Toddy? Filters are what makes the coffee that millions have sworn by since 1964. Designed specifically for the Toddy? Cold Brew System Home Model, Toddy? Filter 2 Packs are sold in cases of 12, providing 24 total filters. Each 2 Pack contains its own hang tag with barcode, allowing for quick and easy resale opportunities. Filters are suggested to be changed after 10 to 12 uses or after three months, whichever comes first. Cleaning simply requires rinsing under running water to remove any residue, squeezing off any moisture, and storing in an airtight container in your refrigerator in between uses. No soap needed.
