  1. CADR is not an airflow metric. It is airflow multiplied by the fraction of air output which is clean. Although, I'm not sure how well they tested it in the video because I haven't seen it yet.

  2. ​ @maluminse6013 That would be like saying a $2 50W lightbulb will be as bright as a $20 50W lightbulb. That's not the case, because the $20 one is an LED, so more of the energy actually goes to lighting the room and less is wasted, so it will be brighter with the same power. The same probably applies for heaters.
