Follow these steps: Remove the gasket that surrounds the lid. Remove the metal and paper filter. Locate the slit for the pressure valve. Blow really hard to clear any dust stored in there. If you have a can of pressurized air, even better! Clean the filters. Use a very clean brush on the paper filter, then clean the metal filter. Make sure it has fully dried. Clean the gasket and make sure it’s completely dry. Reseal your Atmos.

We don't recommend storing Atmos (or coffee beans, for that matter) in the freezer since it will likely degrade the silicone seal over time. However, you can store Atmos in the refrigerator without issue.

Coffee (and other dry perishables) go stale for two primary reasons: exposure to oxygen and humidity. it reduces both oxygen and humidity, subsequently extending the life of your coffee by up to 50%.

Atmos is not dishwasher safe. Best is to use a non abrasive damp sponge.
