1. Overview
The Fellow Atmos Vacuum Coffee Canister is engineered to preserve the freshness of your stored goods by actively removing air and limiting oxygen exposure. This innovative design helps prevent oxidation, a primary cause of staleness in coffee, tea, and other perishables. The canister features a robust vacuum seal mechanism and a powerful silicone ring to ensure an airtight environment. This manual provides essential instructions for the proper setup, operation, and maintenance of your Atmos canister to ensure optimal performance and longevity.

- Spices
- Peppercorns
- Other dry goods sensitive to air and moisture

2. Setup
Before using your Fellow Atmos canister for the first time, it is important to prepare it properly:
- Unpack: Carefully remove all components from the packaging.
- Initial Cleaning: Hand wash the glass body and the lid with warm, soapy water.
- Rinse Thoroughly: Ensure all soap residue is completely rinsed off.
- Dry Completely: Allow all components to air dry thoroughly before assembly and use. Any residual moisture can affect the vacuum seal.
- Inspect Seal: Verify that the silicone seal on the underside of the lid is clean, free of debris, and properly seated in its groove.
Important: Do not use abrasive cleaners, harsh chemicals, or scrubbers, as these can damage the glass and the delicate sealing components of the lid.
3. Operating Instructions
Follow these steps to effectively use your Fellow Atmos Vacuum Coffee Canister:
- Fill Canister: Place your desired contents (e.g., coffee beans, tea leaves, spices) into the glass body of the canister. Ensure you do not overfill; leave at least an inch of space from the rim to allow the lid mechanism to function correctly.
- Attach Lid: Place the lid firmly onto the canister.
- Create Vacuum Seal: To activate the vacuum seal, twist the lid back and forth repeatedly. You will feel resistance as air is extracted from the canister. Continue twisting until the small green indicator dot on the lid is fully visible. This indicates a successful vacuum seal.
- Release Vacuum and Open: To open the canister, press the small button located in the center of the lid. You will hear a distinct hiss as air re-enters the canister, and the green indicator dot will disappear. Once the air has been released, you can easily lift the lid.
The vacuum seal is designed to maintain freshness for approximately one week when the canister remains unopened. For optimal freshness, re-seal the canister after each use.

4. Maintenance
Proper care and maintenance will ensure the longevity and effectiveness of your Atmos canister:
- Hand Wash Only: The Fellow Atmos canister is not dishwasher safe. Always hand wash the glass body and the lid.
- Cleaning Procedure: Wash all parts with warm, soapy water after each use. Rinse thoroughly to remove any soap residue or food particles.
- Drying: Ensure all components are completely dry before reassembling and storing. Moisture can compromise the vacuum seal and potentially lead to mold growth.
- Seal Inspection: Periodically inspect the silicone ring on the lid for any signs of wear, cracks, or damage. A damaged seal can prevent the canister from holding a vacuum.
- Storage: Store the canister in a cool, dry place away from direct sunlight.
5. Troubleshooting
If you encounter issues with your Atmos canister, refer to the following common problems and solutions:
- Problem: Canister not holding vacuum / Green dot not appearing
- Solution 1: Ensure the lid is properly seated and twisted firmly until the green dot is fully visible. Sometimes a few extra twists are needed to achieve a complete vacuum.
- Solution 2: Check the silicone seal for any debris, damage, or improper seating. Clean the seal and the rim of the canister, then reposition the seal if necessary. Even small particles can compromise the seal.
- Solution 3: Verify that the canister rim and the underside of the lid are clean and dry, free from any particles or moisture that could prevent a proper seal.
- Problem: Difficulty opening the canister
- Solution 1: Press the release button firmly and hold it until you hear the air hiss. If the button feels stuck, gently wiggle it while pressing.
- Solution 2: If the canister has been sealed for an extended period, the vacuum might be very strong. Ensure the release button is fully depressed to allow sufficient air re-entry.
- Problem: Canister capacity concerns
- Information: A 1.2L Atmos canister is generally designed to hold a standard 12 oz (approximately 340g) bag of whole coffee beans. Larger bags (16 oz or more) may require multiple canisters or a larger Atmos model.
