Bests & Worsts Reviews from Amazon

I was really hoping this would work. I have an African grey parrot who has dandruff. It’s been recommended i get an air purifier to help cut it down floating in the air. As soon as i plugged it in it went red to yellow to green “clean air”. This took about 15 mins. I’m still seeing the dandruff floating around in the air. It ran about 6 hours in the green all day. I decided to unplug for less than a min and plugged back in and turned power back on. It started as red the went yellow and finally turning green again after 15mins again. How did the air get so bad in less than a min? To me it looks like it’s a scam and programmed to go thru that 15min red,yellow, green. Plus i see non of the partials being drawn to the unit.
