Levoit - Superior 6000S Six Gallons Smart Evaporative Humidifier - White

I bought this evaporative Humidifier because I have several musical instruments in my apartment. Musical instruments are not happy or healthy in a dry environment. This is why you often see instruments kept in a separate room in quality music stores. The Humidifier also helps the instruments stay in tune. One of my many instruments is a Hammered Dulcimer. Before I bought the humidifier, I could hear the strings or the wood that holds the strings pinging because the room was too dry.. A dry room can also do permanent damage to your instruments in cold weather.

Does a good job humidifying the house but it sometimes makes a squealing noise and I don't know why or how to make it stop. Filters need cleaning every time we fill the tank.

This is the best evaporative humidifier with a large capacity out there for us... we considered the Venta (neighbor has one) and tried the Vornado 4 gallon. Venta's airflow design isn't ideal for sitting next to a wall or in the corner, which is very problematic in a tight NYC apt. 6 gallon is bigger than Vornado's 4, and the refill method is much easier. We use NYC tap water, which is soft, so folks with bad/hard water may be better off with a wicking action like the Vornado instead of pumping action like this one. Some tips: Make sure you use a water bacteriostatic additive like Essick/BestAir/Venta/etc. Or mix your own like we do... they all use some combination of a quat (we use Steramine tablets) and citric acid (we get food grade powder) or ethyl alcohol. Use the app to be able to use Humidity Fan mode instead of Humidity Smart mode or Auto, which allows you to keep the fan speed low and quiet. Things that Levoit can improve: better wheels, a bigger/taller capacity model, more fine-tuned control in the app around humidity targets. Right now, if you set a target humidity, it will kick own when humidity is target minus 5% and keep running until it gets to target. I would prefer to be able to set the range of off & on to control when it kicks on and when it goes off. We currently use the app to set it at 43% so it fluctuates in a 5% range around our ideal of 40% humidity.

Overall a decent unit, especially for the price and claimed capability for whole house use. A few issue I have with its operation after having for a couple of weeks. 1) when the unit is full of water, the wheels are less than stellar upon moving to its designated running location. It is hard to steer and requires more "push" effort than it should. 2) filling the unit is a pain. You must remove the top portion to get to the fill hole, and by doing so, results in water getting on the floor. 3) The suction unit that dangles from the filter assembly sheds water everywhere when you have to remove the mid-section for its recommended semi-daily cleaning/emptying. 4) it has trouble attempting run and stay at the set humidity level; it tends to run lower than the desired setting, only kicking it up a notch when you apparently walk by the unit stirring the air and triggering its sensor that it's too low a humidity. * The large capacity water tank is nice, the unit is relatively quiet for its size, and it has a nice remote-control app. How long it lasts is going to be key. The replacement of the 4 filters looks to be a routine expense that is not insignificant too.

This machine WILL disconnect from your wifi multiple times per week for no reason. (That error code is "ES".) You'll reconnect it back to your wifi, and it'll disconnect within seconds. The machine will turn on and off whenever IT wants to. The app will not display all operating options or any helpful info on how to fix the issue. Repeat these steps an indefinite amount of times! If that isn't enough, the filters degrade QUICKLY by mold! Your windows will have so much condensation on them that they'll sweat and mold up your window frames and window sills. You will need to clean the tank out every 3 days to prevent mold; which is a lot of upkeep (especially for those physically disabled). To close out, even if the machine didn't have any of the above problems - it's LOUD and it produces so much wind that you'll feel chilly in the room it's set up in. Get the cheaper version if you need a non-frustrating humidifier!
