text: the problem could be the formaldehyde in the plastics of the AC units... try letting it run a few times all day long while you are gone to work or school or someplace... \n\nthe new in your ac should go away sooner or later so that you can stand to be in the same room with it...\n\nanother idea- try changing the filter - the one that came on it may be full of lint and dust from shipping\n\ngood luck- \nsusan
