Does it work for hay fever?
Thank is a serious health condition and you should treat it, instead to just use a mask ! The best medicine is called Montelukast ! Will let you breathing free, even in a pollution day . anyway, avoid stay outside . You can combine Loratadine with Montelukast , in the evening before go to sleep. For me worked great ! I had allergy that made me cannot breathing almost at all. Once started this pills, all is normal back.
