This Dyson has a multi-stage filtration system
Dyson's fully sealed filtration system traps 99.97% of 0.1 micron particles and allergens - and blows out cleaner air than the room air you breathe. There is no need for an additional Hepa filter. The Dyson absolute is the lightest and is equipped with hair detangling technology designed for pet owners. The Detect Slim Total clean is also equipped with a high efficiency Hepa filter.
