Abstract
There is described an improved clean room helmet system including a helmet having an inlet port and an exhaust port. Connected to the inlet port is a portable and mobile pressure filtering system for suppling filtered air to the helmet. A separate portable and mobile vacuum filtering system is connected to the outlet port on the helmet for exhausting and filtering all air removed from the interior of said helmet before exhausting the air into the atmosphere. All air fed to the helmet is filtered and all air exhausted from the helmet is filtered thereby protecting the user from breathing contaminated air. The system also protects those persons in the environment from air being exhausted from the helmet into the environment. A deflector located within the helmet prevents pressurized air entering the inlet port from being fed directly to the exhaust port located on the helmet.
