Thanks for the detailed review! I received my Dreo air purifier today, and I'm impressed. Unlike the Shark Air Purifier 3-in-1 with True HEPA Filter (HC452) that I initially purchased, which had limited airflow and air outlet, the Dreo has a very powerful airflow. It comes with an app, a remote, and is perfect for large rooms, doing exactly what it's supposed to do.
I believe we have the Levoit 300s sitting around in our studio yet to be processed/reviewed. I would expect similar results but if I just made a guess the Levoit may do better since that is their bread and butter!!
