Sound Level
On the high setting, the airflow produces a noise equivalent to a normal conversation. On the medium setting, the sound level is low enough not to interfere with conversation or study. On low, the machine is very quiet. The constant, smooth sound of the airflow is referred to as “white noise.” The white noise of the Austin Air cleaner blocks out annoying sounds like barking dogs or car horns, which can interfere with sleep.

Does the Machine Cool the Air?
No, the air is always room temperature. When room temperature air is blown over your exposed skin, it feels cool because your body is about 30 degrees warmer than the air in the room. The air cleaner does not cool the air in your room.
