Really Bad allergy attacks?

Unfortunately, you will not be able to remove all dander from your apartment, though there are some other things you could consider doing. If you haven't tried dusting ALL your surfaces with something other than a feather duster(which will just throw dander into the air), you could try that. If you have curtains or non-leather furniture, you should also try vacuuming those out as well ! Good luck ! Hope your boyfriend feels better !
