Review on Efficient Home Humidifier: Powerful 2.1Gal/8L Large Room Whole House Top Fill Humidifier | Covers 500 sq.ft. | Quiet Operation | Runs up to 48 Hours | Auto Shut-Off | Easy to Clean by Monica Williams

Overall a very good humidifier but my product was faulty, the humidity sensor didn't work. It stayed at 38% and lasted 24 hours. I placed the moisture meter in the same position as the humidifier and it went from 39% to 55%. I really need an auto-stop function based on the set humidity level, but it seems like the one I have never will. Edit: After 3 days the whole device stopped working. I can turn it on, but there is no fog even with a full water tank. Edit: A week after replacing the device, it stopped working. Garbage. Stay away!
