Whole-machine HEPA filtration
Certified asthma & allergy friendly™. No other vacuum expels cleaner air.
Other vacuums often have inefficient cyclones, which means that microscopic particles like mold spores and pollen make their way through to the filter. If the machine isn't properly sealed, these allergens and other microscopic particles escape back into the home.
Radial Root Cyclone™ technology captures allergens and bacteria. And the whole system is engineered to be completely sealed . That's helped the Dyson Ball vacuum become certified asthma & allergy friendly™ by the Asthma and Allergy Foundation of America. It went through an independent program of rigorous tests, meeting – and exceeding – the strict criteria.
Dyson vacuums have the most efficient cyclones and are engineered to be airtight. What goes into the vacuum goes into the clear bin – not back into the home.
