I'm staying in an extended stay hotel. It's nice and clean with friendly helpful staff. I have noticed one possible issue though. On a couple of occasions I've turned on the fan to "constant mode" during the night. On those occasions I've woken to a pretty good headache. Despite the use of allergy and headache meds I can't rid myself of the headache for an entire day. On nights when I don't have the air unit's fan on constant I might wake up to a slight headache which goes away fairly quickly. Overall any headaches I tend to get are quickly resolved with some headache meds. Outdoors I tend to get headaches if out in the country setting if I haven't taken allergy meds before hand.

There is no smoking allowed in the hotel and they'll fine a person $250 if they are caught smoking in the hotel. I've checked the air unit and it's clean and free of any noticeable signs of pollutants.

My options for a temporary place to stay are somewhat limited. I could go somewhere else I suppose but don't intend to. Complaining to the front desk staff would likely be useless as they are little more than store minders. What I intend to do is contact the corporate office and tell my story and see what if any actions they take. Furthermore I intend to write a public review of this place pointing out my experience to those that might want to use this same facility. Overall I can't prove anything. It's simply cause and effect that led me to a conclusion that the hotel's air duct work may in fact be, shall we say, unclean. I don't get headaches like this at my home despite using a fan all night every night. The hotel isn't exactly ancient either.

Anyone have a similar experience?
