Any industrial supply vendor with worker safety items carries the respirators. Even Home Depot and Lowe's stock them in the (spray) painting section. Places like gemplers.com have them online. Many of the actual filters are made by 3M.

During the SARS scare most Home Deports and Lowes sold out of the respirators, and that was with relatively few people aware of the situation. Anyone who takes the possibility of a high-morbidity flu epidemic seriesly would be wise to invest $25 in a respirator now. Also would protect against numerous kinds of bio and chemical WMD.
