I have a rare form of allergy/COPD in that I have breathing reactions to chemicals odors including detergents, cleaning products, perfumes, scents etc. So, years ago we switched to only using Sport Wash year-round in the washing machine and never any kind of fabric softener in the washing machine nor the dryer. I only bathe using Scent-Away soap and only use scent away deodorant. I also replaced all the carpeting on all floors of the house with 3/4" oak tongue and groove hardwood floors and removed all draperies and cloth furniture from the house. It's all made a big difference for my condition, and I have significantly fewer wheezing issues and asthma attacks. You only need a tiny amount of the scent-away deodorant so go lightly when applying it.
