Abstract

See full text

An air filtering apparatus includes a fan body having an air intake and an air outlet. There is a fan within the body which draws air into the intake and forces it out of the outlet. There is at least one air filter between the intake and the outlet. A plenum chamber is connected to the fan body about the air outlet. The plenum chamber is a flexible bag of a sheet-like material which is inflated by air forced out of the outlet of the fan body. At least a portion of the plenum chamber is an air diffuser for air exiting the apparatus. The diffuser is more permeable than the filter.
