Users' feedback

Users quotes on Amazon.comWILDLY inaccurate hygrometer Just purchased and I can echo another user's comments where the hygrometer is WILDLY inaccurate. This has also been my issue with past Aero-Swiss / Boneco products. This particular model is reading humidity levels at least 20-30% higher than multiple hygrometers in the same room. When the unit turns on it thinks it gets a 350 sq ft room from 20% to 40% in less than a minute and then turns off. If I just use the timer function and not the Auto setting it functions fine but safe to say this is a premium product and does not function like one. Will most likely be returning for a lower end unit. Nice design, quiet, but inaccurate builtin hygrometer I bought this from bedbathbeyond. It is sleek, pretty, and very quiet. The output mist is good. Easy to use with the touch panel. "

Users quotes on Amazon.comA few issues I noticed (which should be improved for a $200 humidifier) The touch panel is not very sensitive. You have to "push" instead of "touch" The manual says there is an "ionic silver stick" embedded in the left part of the tank, but I didn't see it. I saw the slot for it there, but no stick. Maybe it's not equipped in the models sold in the US? Better make it clear. I am not sure if it's just missing or not included at all. The biggest issue I have is with the built-in hygrometer and auto mode. With auto mode on it will automatically turn off if the humidity level is 50%. But the built-in hygrometer is very inaccurate. I turned it on in a very dry winter room for two hours, and it shows the humidity level is 85% and turned itself off! I don't think that is true since I still feel very dry, and one of another external hygrometer says the humidity in the room is just 30%. So I have to turn off the auto mode, disable humidity level settings (by setting it to Co, which means Continuous), so it will generate mist. "

Conclusion: U350 by Boneco

After a thorough dive into the Boneco U350 ultrasonic humidifier, we have determined it’s a great home tool that provides an adequate humidity level for your room. The unit creates a cool moist environment which is automatically controlled and requires little or no concern once it has been set up.
