and they will cycle the air four to five times per hour in a room that size,
Is that all the air or part of it? And does that matter? i.e. anyone knows whether smoke particles etc automatically dillute or rather stay in the same concentration given one volume of air? I mean, I can imagine if you put one of these things in the center of the room, it will take in air and spit it out, but unless there is some constant process also taking volumes of air away from the far away corners, behind tables/beds/couches and getting it to be sucked up by the machine, the machine is always cleaning the 'same' air hereby leaving volumes of air far away from it untouched and hence possibly still polluted? Or isn't that how it works because there always is some kind of air flow going on somehow leading to all air making it through the machine?
