Turn your Carter into a complete brewing system.

The Fellow Carter Infuser snaps securely into compatible Carter mugs, allowing you to steep loose-leaf tea, brew cold brew coffee, or infuse water with fruit and herbs — all in the same vessel you drink from. No extra gear. No mess.

The fine-cut mesh basket is designed to allow tea leaves to fully expand while keeping sediment out of your cup. When you’re ready to sip, simply remove the infuser — or leave it in for continued steeping on the go.
