A vacuum's filtration system determines the size and number of dust particles that remain in the air when the air is expelled from the vacuum. Microfiltration was the most common filter type for vacuums for a long time until HEPA (high-efficiency particulate absorption) filters came along. Still, microfiltration is efficiently designed for high airflow performance with a unique quality that attracts dust particles. For households where occupants suffer from allergic reactions to pollen, dust mites, and tobacco smoke, or for those demanding a cleaner indoor environment, microfiltration features may offer a solution.
