My daughter has seasonal allergies, which has turned into all year allergies that causes nosebleeds. I bought The Crane Cool Mist Drop Shape Humidifier to put in her room to keep moisture in the air, and it has helped tremendously. I like that it runs 24 hours, and automatically shuts off if the tank is out of water. The Crane humidifier doesn't require a filter, which is a big plus, and its quiet so it doesn't interfere with her sleep. The tank is easy to fill, and is good for a 500 square foot room, BPA free, and produces up to 2.3 gallons of moisture when running 24hrs. It doesn't have to be just winter to have a humidifier running in your home, it's good all year long, the moisture helps with dry hair, which causes static, and dry skin. Also, I clean mine every week or so with vinegar and water to keep it running at it's best.
