MIRACLE is one of the best dust collectors we have tested. It is truly remarkable.

Has MULTIPLE (gradual) speeds

Comes with ONE HEPA filer installed and 50 disposable filters. HEPA Filter requires daily cleaning (gently clean it with a dry brush over the trash can) or gently suck it with a vacuume cleaner at lower speeds.. Recommended to replace every 3 months of daily use.
Disposable filters (napkins) can be used instead of a HEPA filter (but not together with it!). Discard each after use.
