I have an Electrolux vacuum cleaner, so I have to use the S-Bag. I have used regular and these bags. They are made of a thicker material to ensure dust and particles stay inside. So the vacuum cleaner doesn't seem to smell that bad either. On the other hand, the capacity is slightly lower, so they have to be changed more often. Also, when it comes time to replace the bag, I usually rip off the cardboard lid that should be closed. Pocket. Not because I want to, but because the bag is full and I don't fully cooperate. So I have to have a garbage bag handy so I don't spill it on the floor. They're a bit more expensive than regular ones, but if you value extra filtering, they're worth it.
