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.8

Ceramic plates for fast heating
PTC ceramic plates heat the air as it’s projected, with built-in thermostats which can save you up to 30% in running costs while maintaining room temperature.11

Destroys formaldehyde in billions of catalytic tunnels
Dyson's unique SCO filter continuously traps and converts formaldehyde into water and CO₂.5 And it self-regenerates, so it never needs replacing.

Frequently asked questions
The Dyson Purifier Hot+Cool Formaldehyde features Air Multiplier™ technology for powerful, long-range air projection, delivering a maximum airflow of 290 litres of air per second.
In tests we found this machine suitable for room sizes up to 27m2.
We would advise owners not to use an extension cable when using the Dyson Purifier Hot+Cool Formaldehyde.
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.
