Wiix . . . have you ever considered that you should not have dust catchers like the canopy, being as you are hyper-sensitive to dust? I have read many times that those with dust allergies often contribute by they way that they furnish their homes. You might be better off eliminating those furnishings that noticeably catch or trap dust. I know we constantly monitor around here for things that collect dust, just to be on the safe side, as my partner has early stages of COPD.
