Does anyone make in-the-wall humidifiers that are silent ( like ultrasonic ) but won't put out minerals or chlorine? We want something for our bird room, that won't make noise when it comes on, like our Aprilaire 360 does, because we don't want to scare the birds at night while they sleep.
We don't have an Ultrasonic Wall unit. Our 360 is our only wall through offering. This unit has a decibel rating of 73.
One option might be our 800 steam humidifier with our 850 fan pack. The fan pack would be mounted in the wall and has a decibel rating of 50. There would be some fill and drain noises associated with the 800 itself but those could potentially be mitigated by an installer.
