Humidifier Cool Mist HUM-CM50B by Homedics suitable for spaces up to 50 m². It uses the almost silent and economical operation of ultrasonics to convert water into steam, thereby increasing the humidity levels in the room. Practically, by placing water in the special receptacle and turning it on, it converts the water into steam through ultrasonics. Essentially, it revitalizes and improves the air in the room, making it cleaner and more humid, and will benefit people who suffer from dry skin or respiratory problems. You should regularly clean the water tank to ensure that the steam it emits is always clean and does not pollute the atmosphere.
