Abstract

A personal respirator has a face mask and is provided with a filter unit comprising a canister housing contiguous layers of novel filter material. The filter material is suitable for both particulate and vapor filtration, and comprises a composite of first and second groups of chopped fibres, the fibres of the first group having a relatively large diameter (about 7x10<-6 >m) and the second group having a relatively small diameter (about 0.5x10<-6 >m).
