    摘要： There is herein described an improved laser smoke particulate/odor filter including an upstream gross particulate portion that both filters and disperses the smoke, a single charcoal odor adsorption portion, a downstream particulate portion for removing smaller gross particles, and a final filtering portion for filtering out any remaining undesirable contaminated particulate. Another embodiment utilizes an upstream particulate portion that filters and disperses the smoke followed by a first and second charcoal adsorption portions of unequal sizes that are separated by a second smoke dispersion member disposed between the first and second charcoal odor adsorption portions.

    摘要： There is described a portable and mobile clean room helmet system including a helmet having a removable face shield connected to a battery-powered filtering system for pulling air from within the helmet and exhausting filtered air to the outside environment. The removable face shield contains a plurality of unique flapper valves that allow air to enter the helmet system while at the same time preventing unfiltered air from leaving the system.

    摘要： 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.
