Frequently asked questions

What is an allergy-friendly vacuum?

An allergy-friendly vacuum can make life more comfortable for people living with allergies. These machines pick up microscopic allergen particles and fine dust in the home and often feature de-tangling technology to remove hair. Our latest vacuums give scientific proof of a deep clean and is engineered to reveal, capture, and trap the dirt and hair left by people and pet. Our latest pioneering vacuum technology comes with fully-sealed filtration. So allergen particles remain inside.

Does HEPA filtration remove allergens?

Dyson vacuum filters are engineered to trap microscopic particles and allergens. Our sophisticated filtration system captures 99.99% of allergens as small as 0.3 microns⁴ – and expels clean air. HEPA filtration goes a step further and the standard demands not only for the final post-motor filter in a vacuum to be HEPA-grade, but every single filter and seal throughout the machine. HEPA filtration is available on the Dyson V15 Detect™ vacuum and traps 99.97 per cent of microscopic particles and allergens as small as 0.1 microns.⁵

Does vacuuming help reduce allergens?

If pet hair and allergens are a problem for you, it’s recommended to use a vacuum with extra strong suction power, and to vacuum your home on a regular basis. Don’t allow dust, pet hair and dander to accumulate. It’s also important to vacuum your mattress and upholstery. Thanks to new, unique technology, Dyson cordless vacuums can detect and pick up even the tiniest dust particles and hair.
