Review on Ultimate Germ Guardian True HEPA Air Purifier: Eliminate Germs, Allergens, Smoke, and Odors with UV Light Sanitizer and 4-in-1 Filtration - Ideal for Home AC5350B by Chris Wyffels

Just bought the unit. That's fine and all, but I have serious concerns about the air cleaner outlet blowing air back to the inlet. I think this creates a recirculation loop that reduces the amount of unfiltered air to be filtered. Ideally, the unit should blow and exhaust the filtered air away from the unit to ensure complete circulation in the room. I'm an engineer and maybe I analyze too much, but this seems to be a big problem. I think most of the air that went through the filter is air that just came out of the air purifier.
