Whole-machine HEPA filtration
Other vacuums often have inefficient cyclones, which means that microscopic particles like mold spores and pollen make their way through to the filter. But a filter on its own, no matter how good, is not enough. The filter and the airways around it also need to be sealed to prevent these allergens and other particles being thrown back into the home.
Dyson vacuums have the most efficient cyclones, and all of the airways and the filter housing are engineered to be airtight. So, what goes into the vacuum goes into the clear bin – not back into the home.
