Deserves Zero Stars - fan didn't turn
Ordered this because of the terrible smoke from wildfires.  Local stores within a 90 mile radius are sold out of air purifiers.  The product arrived in 3 days.  Great!  Quite small.  Easy to set up.  Didn't work a lick.  The 3" fan did not move. All it is is a small fan that draws air in through an air filter.  Absolutely worthless if the fan doesn't turn.  Frankly hard to imagine it being helpful even if the fan did turn, but I see it has gotten good reviews from others.  So I'm getting a refund and still breathing smoky air.  Darn, I needed this! Good luck to others in the same boat.
