Excellent air cleaning....much better than my delivery experience in which you delivered to the incorrect address and then wanted me to fill in a time consuming claim!

Unit turns itself off.
The unit constantly turns off at random times. If I unplug it for 10+ seconds and plug it back in it turns back on. I did a factory rest and it was fine for a day but not now.
