Review on 🏠 Colzer Ultra Quiet Essential Oil Air Purifier for Home Bedroom 3000 Sq.Ft/s Purify Fresh Air, Effectively Captures Pet Dander, Eliminates Odors or Smoke with 360°HEPA Activated Carbon Filter, Wifi Control Model KJ580 by Cindy Moore

I also have 3500sqft units from Colzer they are amazing and I was very disappointed with this unit. The air quality reading jumps a lot on both (I have two models of this model), while the other larger device next to it doesn't. My laser particle counter doesn't work either. Also, fan speed control is poor and noisier than larger units. I've also had issues with WiFi connectivity, I couldn't get either of the two devices I bought to work with WiFi at all, and I'm a highly skilled WiFi technician. I am returning both of my devices for a refund.
