Can I store ground coffee in my Atmos?: We recommend storing only whole bean coffee in your Atmos. Storing ground coffee or other fine substances may clog the intake valve and prevent a proper vacuum seal and may also void the warranty.

The Atmos is designed to hold a vacuum for approximately 3-4 days, storing your coffee beans to use throughout the week. It is not designed for long term shelf storage. As your coffee degasses, you may see the notch level decrease or disappear all-together, and you may need to release the pressure and reseal. How much or how fast your coffee degasses will vary depending on how recently the coffee was roasted, the type of coffee and the roast. Basically, the less gas, the longer your Atmos Canister will keep its seal!
