Miele Type Miele XXL-Pack AirClean GN + HA50

I use these GN bags and HA50 HEPA exhaust filter in my Miele Complete C2 Hard Floor Powerline vacuum. They are expensive, but they are good; the air in my home always feels fresh after I'm done vacuuming.

I do notice that over time, odors from the trapped dust can still get through. That's not surprising, as HEPA media does not filter odors/gases. But since I'm sensitive to that, I have addressed that issue by putting some activated charcoal (like that used in some air purifiers) in the vacuum bag. Of course it makes the inside of the bag and the intake side of the exhaust filter black (doing their job!). I don't know if that harms the vacuum motor at all, but so far I have not had any problems doing that for almost 3 years now, just fresh air.

nothing else to day

The Meile maintenance guide is very difficult to understand how to properly maintain their vacuums.
