Hello,
I have seen here that ultrasonic dental cleaning is considered harmful for our ears.
Does anyone know if this also applies to an ultrasonic humidifier for example?
I want to use one but I don't know if I have to buy this particular type or an older style evaporative one.
Thank you in advance.
