Well the SEBO X range does have a carbon filter fitted above the floor head but as you know the Felix is quite different in this respect. I was just interested, really as Gerry Rubin states quite categorically that SEBO vacuums don't have a low reading, yet fails to provide evidence. Gerry Rubin seems to be all talk and no action sometimes!
As do many single brand vacuum salesmen, he has a tad of larceny in his heart when it comes to his sale's pitch. Not to offend him, or disrespect his sales skills for MIELE because he pitches and pushes the brand very well. MIELE is his forte.
