Are Ultrasonic Humidifier Safe?
For the most part, ultrasonic humidifiers are safe. The ultrasonic frequencies that an ultrasonic humidifier generates are not dangerous to humans and pose no health risk to the user. However, because ultrasonic humidifiers do not use heat to nebulize the water, water contaminants can be projected into the air, which the user breathes in. Water contaminants may include viruses, bacteria, fungi, and minerals and are often referred to as “impurities.” Impurities in an ultrasonic humidifier can be prevented by only using purified water, using some type of filter, and cleaning the device regularly.
