Re: Severe Allergies to Dust
Well, you could go on allergy shots.
Or, you could try to reduce the amount of dust in the apartment. A HEPA filer isn't terribly expensive, maybe $100 for your bedroom. Wash your sheets regularly in hot water. Get rid of clutter, hardwood floors are better than carpet. Also, when you clean, don't use a feather duster. Instead, use a damp cloth or a static dust wiper. (They sell disposable ones in the grocery store.)
Keep in mind, some air specialists may not be reliable. For example, if they work for companies who specialize in cleaning air, they'd be more likely to say that you need their company's services.
