The air isn&rsquot getting any cleaner. And airplanes and trains and buses can be sick, sick places. If you already use an antipollution mask when boarding or driving, or indeed, sightseeing, you may as well stop looking like an escaped patient, and throw some style into it with these spiffy hi-tech masks. They are even washable, so no filter changing. With an N99 rating, they filter out an average of 99.978% of tiny particulates when correctly worn. And come in sizes to suit a child too.
