The Dyson V15's whole-machine filtration traps 99.97% of particles — that matters for pet dander

The Dyson V15’s whole-machine filtration traps 99.97% of particles down to 0.3 microns. That number matters more than most spec sheets suggest — especially for cat dander floating around a child’s bedroom. Standard vacuum filters let microscopic allergens pass right through the bag and back into the air, which defeats the purpose of vacuuming if someone in the house has allergies. The V15’s sealed system means what goes into the bin stays in the bin. For pet owners or allergy households, that’s worth paying extra for.
