Bests & Worsts Reviews from Amazon

I consider this humidifier a good purchase; however, there are some caveats. First the Pro's: (1) It is almost silent, even at the highest output level. I have never owned a more silent ultrasonic humidifier, so this is a treat! (2) It is easy enough to clean, with few "impossible" nooks and crannies. (3) sleep mode (which turns the output on auto up to 50% humidity) works as expected at night. (4) it is easy to operate with just the buttons - no need to use the app. I don't use the app, aroma diffuser, or night light, so I can't comment on those features. Now Cons: (1) I had a powerhouse of a humidifier prior to this one - an Air O Swiss before the company was bought out by Boneco. I still miss that one greatly. It output mist like an illegally-opened fire hydrant in the summertime. Before buying this humidifier, I didn't do my research and mistakenly relied on the size of the tank to indicate whether I thought it would humidify my living room adequately. Both this one and my Air O Swiss are a similar capacity in the water tanks. However, the Levoit struggles in my livingroom to get the humidity past 40% when the radiator is blasting on a cold day (no ability to control the heat output where I live). My living room area is about 400 sqft. The description for this humidifier makes it seem like it should be able to handle a room this size. They clearly did not count on NYC apartment heating. If you are in the same situation as me where you can't control the heat output and they are blasting it, this humidifier is only good for the bedroom. For the living room, you really want something with a mist output that is double or triple the output of this one. I am considering the Levoit LV600S for this reason - mist output is 300ml/h for cold mist and 550ml/h for warm mist. For comparison, my current Levoit humidifier outputs mist at 135mL/hr. I should have paid attention to these numbers from the start. Learn from my mistake! (2) Although this humidifier is much easier to clean than my old humidifier, it still does have a few "impossible" nooks and crannies that a small bottle brush and the tiny (included) brush can't reach. Those areas are permanently discolored with use. This is minor and something I am willing to live with. (3) The hygrometer on the humidifier is often 7 to 10 degrees more generous than reality. I have found hygrometers on humidifiers to be inaccurate across all the different brands I've owned, so I just ignore the humidity number altogether. I have independent hygrometers in every room of my apartment. However, if you are relying ONLY on the hygrometer on this device to assure yourself that you are at the healthy 40% to 60% humidity range, do yourself a favor and get some independent hygrometers. Your nose will thank you.
