Synthetic HEPA all the way.
All of my bagged vacuums except for my F and G Sanitaire use genuine synthetic HEPA bags. The only reason I don’t use them with my Sanitaire is they don’t exist in that type.
With synthetic HEPA bags, you will notice a marked improvement in the following:
- Filtration (obviously)
- Life (it takes noticeably more dust to reduce the airflow)
- Strength (highly unlikely to tear or burst)
