What is HEPA Filtration (Vacuums)?

HEPA (High-Efficiency Particulate Air) filters are designed to capture at least 99.95% of particles down to 0.3 microns, including dust, pollen and pet dander. Vacuum cleaners with a sealed HEPA filtration system are particularly useful for allergy and asthma sufferers, as they prevent fine particles being recirculated back into the room.
