My dear Wife has the same problem (perfumes and scents), but her Doctor diagnosed Situational or Non-Allergic (intrinsic) asthma, but hyperosmia
would certainly factor into it.
In acute cases she has to go on a prednisone script until her system can relax and take over again.
The majority of the human race never take the time to stop and think what their actions are doing to others, all they are concerned about is themselves.
One associate my wife works with applies her perfume several times a day and when she goes through my wife's area, my wife comes home coughing, hacking, and hardly breathing, looking like she's been crying all day. These types of people have gained an immunity to their "odors" and if they can't smell their odor they think they have to add more until they do "smell".
Where do they think they are? Out Partying? You are at work, you're not trying to score (at least you shouldn't be
). You do not have to smell like a $10 hooker, you only have to have no smell at all!
I will tell my wife about your Holmes Aer1-hap9423 find; I wonder if her work will allow it being she works for a large department store and not only has to put up with the associates, but also customers, the customers can't understand why my wife shunts them off to other associates, but my wife is too polite to explain, meanwhile she suffers.
She has mentioned it to her commission customers when they ask why she's suddenly started to hack and cough, and they come back sans any perfumes or scents out of respect for her and the experience she has to offer them to find what they are looking for.
