How to Choose the Right Degassing Valve for Different Coffee Packaging
27 Jul 2026
Freshly roasted coffee continuously releases CO₂. One way degassing valve allows excess gas to escape while preventing outside air from entering, helping preserve coffee freshness.
When selecting a degassing valve, one common question is: Should you choose a valve with a filter or without a filter?
Valves with a filter are designed for applications where coffee fines or powder may enter the valve.
Benefits:
◉Helps prevent coffee particles from entering the valve
◉Reduces the risk of clogging
◉Supports stable venting performance over time
Valves without filters are suitable for applications involving particulates,they feature more open exhaust passages, allowing gas to be vented more efficiently.
Benefits:
◉Faster CO₂ release
◉Higher venting efficiency
◉Suitable for products that generate larger volumes of gas
If your packaging contains fine coffee particles, a filtered valve can help reduce clogging. If maximum venting efficiency is the priority, a withou filter valve may be the better option.
