My sister got me a down comforter for Christmas. Nice, but I'm not sure I can keep it. I have mild asthma that is kept in check with advair and combivent (sp?). My DH has always had a feather pillow in an allergy slipcover and it hasn't bothered me. When I opened the comforter I has an asthma attack (which for me means I had to use my inhaler). Could i keep it if I got an big allergy duvet cover? I can't find any info on that and asthma, only allergies!
