Review on 🔘 BISSELL air320 Smart Air Purifier: HEPA & Carbon Filters, Large Room & Home, Bedroom Air Cleaner, Auto Mode - 2768A (White/Grey) by Carlos Block

I've only had one for about a week. From the moment I received it, the sound it made was uneven. Another reviewer described it very well, so it's not just me. The fan seemed to speed up, then slow down, then speed up again, but I managed to fall asleep despite the erratic noise. However, as I was preparing dinner today, I heard a very loud noise, and it was loud enough to urgently find out what was going on. It sounded like it could be a washing machine that was out of balance, but I didn't. I checked the laundry. Didn't find anything wrong. Checked the back porch. There's nothing there either. I had no choice but to check the bedroom and when I opened the door smoke was billowing out of the air purifier making a loud roar like a propeller plane. I managed to move the heavy dresser away from the wall, turn it off, and carry it outside. I threw away the box it came in so I don't know if they will take it back. I hate to think about what would have happened if I hadn't been home. I would probably come home to find my 2 dogs dead. I cannot recommend it and consider myself lucky that it turned out so well.
