Toddy's unique cold brew filtration extracts all the natural and delicious flavors of coffee and tea, leaving behind the bitter acids and oils associated with the traditional heat-brewing process. Designed specifically for the Toddy® Cold Brew System, Toddy® Filters come 2 to a bag. We recommend replacing felt filters after 10 to 12 uses or after 3 months, whichever comes first. Cleaning simply requires rinsing the filter under running water to remove any residue, squeezing off any moisture, and storing in a resealable plastic bag in the freezer between uses. No soap needed. Toddy® Filters are made in the USA. What's Included: 2-pack of felt filters (2 filters total)
