<html> Hi Tom, Sorry to hear about your problems - what a drag, I got a sore throat the first day, but then turned off the air conditioner at night and opened the window.  Much better, except for the train noises! Later in the week I complained about the bad air conditioning, and the maintenance guy came and opened it up to check it.  There was about an INCH of dust on the filter! He put a new filter in, and the room was dramatically better afterwards. Don Mannino RPT</html>
