If you suffer from seasonal allergies this ultrasonic cool mist humidifier will be your best friend. I especially like the vapor pad it comes with that smells like eucalyptus and spearmint. When I feel congested I turn this on for half and hour and it helps me breathe a little better. It works best in a small room as opposed to a bigger section like a living room but it definitely makes a difference. The nozzle it comes with can be moved to point a certain way. It has 3 settings (low -high) , I like to keep it on low when I'm not in the room and I switch it to high once I'm in the room for maximum effect.
