Hoping you can help me with a question. I work in a very large, old office building, with old heating equipment. Every winter, once the heat is turned on, dust and dirt just pile up on everything in my office. I’ve known for years, but it was recently confirmed that I have severe allergies to dust and dust mites (among others). Like most people with allergies, this includes a runny nose, sinus headaches, sore throat, etc., every day.Would it be appropriate to ask my boss if I could get an air purifier for my office? I am not sure how to approach this, because many people in my department have similar complaints. I know the building is not going to be updated with new heating any time soon. I’ve tried dusting my office myself, but that just sets off the symptoms. My boss is well aware that I have these allergies. I’d bring in my own, but I just can’t afford it. I have one for my home.My biggest issue is, I don’t want to be treated differently from my coworkers who have allergies, but the symptoms are getting out of control. I do allergy shots, and take antihistamines daily, but it could take years before I am allergy-free. Any help would be greatly appreciated.
