Sense of smell & triggers

I can’t say that I smell dust mites, but I do smell mold and it will set my asthma off, also cleaning fluids, new carpeting, or fresh paint, which I mentioned once before. I can walk into a hotel room and I have to run out and start my nebulizer that quick. Also, looking at homes if I walked in and a home had one or more of those plug-in smell things that house was not for me.
