I acutally use a small air filter fan that's meant for kitchens and bathrooms. It's quite small and fits into carry-on baggage with no problem or bulk. Here's the model I use, and it's quite inexpensive, and produces just enough white noise and air for my bedroom at home and a hotel room on the road. http://www.allergybegone.com/hamilton-beach-04251-air-cleaner.html
