However, I had the rear gray filter (believe it is the carbon / catalyst Combi) not as high before looking like the beimB-785 included. However, this can also be a subjective sensation. A star deduction there is that the device only a HEPA filter exchange via LED requested, but there seems to be the only filter in the set, which of course is a waste of money and materials.
