I got TP10 as my upgrade for my TV room. This new machine does amaze me because it has the LCD graph showing the quality of air in the room. LCD do show different colors (red, orange, yellow and green).  When dirty air appears in the room, TP10 runs high until the air is purified.  I feel better knowing the air is clean when I see the LCD graph.  Also, I like the choices of rotation of oscillation. It can rotate at 45, 90, 180 or 350 degrees.  My old machine only can rotate at 90 degree.  I am happy with TP10.
