What Venta has done better in this model? Well, he's bigger than my old air scrubber, which reliably does a very good job for over 4 years and this is more or less in continuous operation in my bedroom. These larger version was a very good acquisition. Even at level 2 when the TV is on, he does his job quietly. As usual, the cleaning and refilling the unit easy and overnight at the latest tobacco and food odors are largely history. Also it is noticeable that less dust on furniture is zufinden and now in winter not dry heated air more annoying mucous membranes. Reason for an even bigger? Maybe a larger apartment. ;-)
