Cool mist vs. warm mist which is better for a bedroom?

For most people, cool mist is the better choice. Cool mist humidifiers are safer (no burn risk), consume less energy, and are recommended by pediatricians for nurseries and children's rooms. Warm mist humidifiers can feel more comfortable in cold climates, may kill slightly more bacteria through boiling, and are quieter since they lack a fan. Both raise humidity equally effectively the temperature of the mist has no measurable impact on room humidity once it disperses.
