Style R and Style U carbon pre-filters:
Since I just bought and installed these today, I'm not sure how they work practically, but I'll see how it goes and report back in the near future. Theoretically, with a Home Solutions filter bag, a carbon pre-filter, and a HEPA after filter, (and, of course, providing the motor is clean!), there should be next to no smell coming out of an Electrolux or Aerus vacuum*. Of course, the new Platinum goes one step better with the second HEPA filter.
UPDATE 08-29-13: I've been using the carbon pre-filters for a couple of weeks now, and they definitely do seem to absorb odors well. It remains to be seen how long they can do so; perhaps they're meant to be replaced at the same time as the after or HEPA filter.
UPDATE 09-05-13: I've since tried the carbon filters in a couple of machines that had fairly full (and smelly) bags as well as used after filters, and the exhaust air smelled quite clean and neutral. It seems, therefore, that these carbon pre-filters do their job.
*My experience with Electrolux and Aerus HEPA filtration has been with the Style R vacuums, so I can't speak about the models that followed, but, as I've pointed out elsewhere in this blog, the Style R HEPA filter works quite well for me. It does a good job of making the house smell cleaner, for a longer time. In addition, since I have more than one Style R machine, each one only gets used semi-regularly, and therefore the bags and filters last for a longer time. With the addition of the carbon filter, the air quality in the house will be even better.
