Review on BONECO U350 Ultrasonic Humidifier: Warm or Cool Mist, Top-Fill Efficiency Unleashed by Taufik ᠌

I bought a humidifier on 11/30, through goods, turned it on on 11/30, pre-prepared the filter according to the instructions, put it on a bedside table and 50 cm from the wall, everything was fine, it worked quietly, it was even more comfortable to sleep with it at night, and in the morning on 01/12 it began to work much louder, turned it down power, but it did not help, after half an hour it began to rumble like a tractor, very loudly. Now I can’t hand it over to goods, because in my personal account since November 30, the status is still that it is at the point of issue, and they still cannot solve this problem.
