Air-O-Swiss S450 Steam Humidifier Customer Q & A

Air-O-Swiss S450 Steam Humidifier Product Details
Q1: I'm interested in the AOS s450 but was concerned with noise. Is this unit produce more noise than the ultra sonic AOS units?

A: Marginally. The ultrasonic don't produce much beyond a slight hum. With the S450 you get a similar sound with the addition of the occasional gurgle. The noise difference isn't noticeable for most people. Hope that helps!

Q2: Does this humidifier have a feature that allows you to use essential oils with it? I know some humidifiers have small oil trays or something similar. Thanks!

A: Yes, at the very top is a small container where you can use essential oils to mix with the steam as it leaves the humidifier.
