Ultrasonic Humidifier safety?

We’ve been using humidifier with tap water for years in our hybrid humidifier. I’m actually finding I can’t even live without it the longer I’ve been using it. If it runs out of water I notice it in an hour just from my eyes getting itchy and dry.

However I’ve just learnt that it’s recommended to use distilled water in an ultrasonic humidifier for health reasons. The ultrasonic apparently puts anything in the water into the air as opposed to “hot” ones that essentially use steam. (And particles remain in the tank where you can clean it out periodically)

Anyway I’ve never even considered this as the tap water here is soft and we don’t get any calcium build up or mold. I’m just curious what others use because I haven’t even seen “hot” ones on sale, Theyre all ultrasonic ones here. And I just don’t see Japanese safety standards being that relaxed that no one would be talking about it in reviews etc if it was a health risk?
