Review on Perfect Aire Personal Travel Humidifier - Ultrasonic Cool Mist with Auto Shut-Off, Ideal for Travel & Small Spaces at Home, Office, Hotels by Constance Bingham

Bought for a disabled friend who cannot carry anything heavier than a personal sized water bottle. She finds it works really well in her dry winter night heat. If you have trouble turning a bottle upside down without splashing water, just freeze the water in the bottle, put it in the holder a few hours before use, it will melt and slightly humidify the space. My girlfriend always alternates between two bottles so she defrosts one in the car and keeps the other chilled in the freezer.
