quote:Originally posted by JuliaI have acquired an allergy or sensitivity to some chemical that is used in many colognes and aftershaves. I have narrowed it down to a chemical because I don't react to all scents and I can stand cigarette smoke and all sorts of other things that regularly allergic people find offensive. I find riding on the bus to work in the morning almost unbearable because everyone on the bus has just applied their scent for the day and I am overwhelmed. I have decided to get a mask and that is why I am writing - to find out what size are common "scent molecules". When we had the SARS scare, the CBC did a test on masks to see which would filter out particles of 0.3 microns. The N95s mask that can be bought in drug stores did the trick. If scent molecules are larger than this, then I can use a simple mask on the bus.
