I think you're being very courteous, if I wasn't clear on that before. You might try the air filter idea, but I honestly can't remember what I paid for my little one and don't know if you want to part with the money. And a good air filter is just heaven--like getting fresh mountain air. I bought my parents a big one for their house (mainly so I could go there without dying, being allergic to cats and dust). One reason my allergies are so bad is growing up in a house with cats, tons of dust, no vacuum (but a carpet in my room), and a woodburning stove.
