It uses high-frequency vibrations to break water into fine particles (1-5 microns), creating a cool mist that mixes with the air. A comfortable room humidity level is between 40% and 60%. Insufficient humidity, especially during heating seasons, can negatively affect human health, pets, plants, and furniture.
