Panasonic F-P15HU2 Air Purifier With Hepa Filter: Great Auto-Sensor Unit(by
apaullo57) I have three parrots in a room, and this unit is exactly what I was looking for. I especially like the automatic air sensor feature on the Panasonic, which cycles the unit on and off depending on the amount of dust in the air. I can see the air rating lights change from green to red when I go into the room and move things around (stirring up dust).
