My lid does not seem airtight, what’s wrong?

Our lid is loose by design so it will fit into the filter. When installing the lid without the stainless-steel filter, please wiggle it around once installed to establish an airtight seal. Keep in mind that the lid is airtight, but not completely watertight as a carafe full of coffee will have enough water pressure to force the coffee past the silicone seal. Thus, we recommend not tipping the carafe over when full.

Please see the video demonstration of how to install the lid and form an airtight seal?
