UPDATE: I’m actually bumping this into 5 stars. The hygrometer is working much better and the humidifier is maintaining the room well right around 45%. It’s super quiet and lasts a long time with the large tank. As long as this thing keeps working as it should, I am very happy with it!UPDATE: After a couple more days of use, the hygrometer appears to be getting more accurate. It seems as if the abnormally high readings occur after filling the tank full, but this seems to improve as the unit is used.ORIGINAL REVIEWWe just received this humidifier a couple days ago and so far it’s been working well. I’m using it in an upstairs room where I keep some guitars to keep the humidity controlled during the cold winter months.We have an integrated whole home humidifier hooked to our furnace, but prefer not to keep the whole house too humidified to reduce condensation buildup on the windows. This little unit does a nice job for a small to medium size room and the extra large capacity is really nice, only have to fill it every 2-3 days even running almost constantly. Having the app and WiFi capability is nice as I can remotely control it even when not at home.My biggest gripe is the hygrometer reading is WAY off compared to my other in-room hygrometer, which makes the Auto function almost useless. Readings are constantly 10-15% higher than actual, mainly because it seems like the unit’s hygrometer sits quite nearby where the mist is being expelled (it appears it’s probably on the back of the unit head, but even with the mist shooting away from it, readings are quite off).So if you’re looking for accuracy to use the Auto function, this may not be the best unit, but if you plan to keep the humidifier running constantly during the very dry winter months and prefer large capacity for minimal refills, this is a good unit to consider. I obviously can’t speak on the long term function of the unit, hopefully it holds up as I know a lot of these types tend to work for a year or two and then go kaput.
