Ultrasonic Humidifier - Warm and Cool Mist
Ultrasonic Humidifier - Warm and Cool Mist
Researching humidifiers on Amazon was a somewhat
tiresome exercise. Almost all products I looked at are subject to very
serious complaints, most importantly noise, leakage, and lack of
reliability. I decided to go with the AOS 7147 because most reviewers
agree that it is really quiet, and because I liked the clean look and
the features.
Here is what I can report after about a week of usage (will update if anything changes over time):
Noise level: Both my wife and I are extremely noise sensitive, but this unit can operate in our bedroom without affecting our sleep. Yes, there is a bit of a humming noise, but it is barely audible. Also there is a bubbling noise once in a while when water flows out of the tank into the tray. All-in-all, it seems about as quiet as can reasonably be expected.
Effectiveness: We use the auto setting that lets the device decide the target level of humidity and the output level. This works very well and hassle free, keeping the room comfortably moist.
Warm mist setting: I would recommend having it. Without it the room feels cool and damp. Even with using it there is a bit of a cooling effect, but it is acceptable.
Filtering/water treatment: We did not see any white dust around the unit, which was a concern.
Reliability/ease of use: No problems so far, straight-forward to operate, everything works as intended. I will post updates, if something comes up.
Look: Matters more than you would think, because it is supposed to be three feet away from the ground and away from both heating and return vents. Inevitably it will end up in a rather visible place. This unit has a bit of a techy, but overall relatively neutral look, better than most.
In summary, I am very happy with this unit.
