During charging cylinder filling with regulated refrigerant, the vapor vented from the top of the cylinder should be recovered.

Vapor management during charging is about capturing refrigerant vapors rather than letting them escape. When charging a cylinder with regulated refrigerant, the gas that vents from the top must be recovered so it can be recycled or reclaimed instead of released to the atmosphere. This protects the environment and complies with EPA requirements. Venting to atmosphere would release refrigerant directly, which is not allowed. Condensing and venting to atmosphere still results in release of gas, so it isn’t the proper approach. Filtering would not remove or capture the refrigerant—filtration doesn’t address the need to prevent emissions. The correct practice is to route the vented vapor into a refrigerant recovery system or into a recovery cylinder so it can be recovered.
