Review on Crucial Vacuum Replacement Hoover Bags - Type Y Model Compatible - Bulk (9 Pack) by Diane Diaz
The quality of the HEPA filtration depends only on the integrity of the connection
Although cheap, they lack the resilient plastic gasket material around the bag inlet. This allows dirt and pollen to seep around the intake pipe and back into the house. HEPA filtration is only as good as the seam integrity. You can also just use a non-HEPA filter. Either that, or you'll need to seal the area around the filter inlet tube somehow.
Pros
- Consistent test results
Cons
- A newer model could have been chosen
