Fully sealed whole-machine filtration
In our latest purifiers, it's not just the filter that meets HEPA H13 standard, it's the whole machine. So what goes inside, stays inside.⁹

Destroys formaldehyde in billions of catalytic tunnels
Dyson's unique SCO filter continuously traps and converts formaldehyde into water and CO₂.⁺ And it self-regenerates, so it never needs replacing.

Frequently asked questions
Dyson engineers are perfectionists. Channeling our relentless dissatisfaction, we have re-engineered our latest purifiers to be fully sealed to HEPA H13 standard.⁹ Two phases of purification sit within a fully-sealed filtration and airflow system to trap pollutants inside, preventing them from leaking back into the air you breathe.
The Dyson Purifier Formaldehyde range has all of the capabilities found in our advanced purification products, but goes a step further to detect and destroy formaldehyde.⁺ An added solid-state sensor precisely detects formaldehyde, while our catalytic filter breaks it down into two safer molecules – carbon dioxide and water.
Formaldehyde is a polluting gas formed of carbon, hydrogen, and oxygen that is commonly found in homes. Sources of formaldehyde in your home could include paint and varnishes, air fresheners, mattresses, furniture, household cleaners, carpets, particleboard and plywood, electronics, dryer sheets, nail polish remover, moth balls, toys, fireplaces, and wood burning stoves.
Formaldehyde is a polluting gas formed of carbon, hydrogen, and oxygen that is commonly found in homes. Sources of formaldehyde in your home could include paint and varnishes, glues, air fresheners, mattresses, furniture, household cleaners, carpets, particleboard and plywood, electronics, dryer sheets, nail polish remover, moth balls, toys, fireplaces, and wood burning stoves.
HEPA grades refer to filter efficiency at a certain particle size. HEPA H13 is a filter with a 99.95% removal efficiency of particles down to 0.1 microns per litre of air. This includes common pollutants such as allergens, bacteria, viruses, pollen, and mould spores.
We recommend replacing the HEPA+Carbon filter roughly every 12 months, depending on how often you use it. That’s because over time filters can become clogged with pollutants and even let unpleasant odours back into the room. The machine will alert you when it’s time to change filters. A filter life reading can be found on the LCD screen and via the myDyson app.⁷ The SCO filter never needs replacing.
This machine is compliant with safety standard UL 1278, as required by the US government. For this reason, heating and temperature control are not available in the myDyson app.⁵ Please use your machine’s remote control instead.
