Frequently asked questions

What's new about the Dyson Purifier range and how is it different to other purifiers?

Dyson engineers are perfectionists. Channeling our relentless dissatisfaction, we have re-engineered our latest purifiers to be fully sealed to HEPA H13 standard.⁷ 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.

What's different about the Dyson Purifier Formaldehyde range?

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.² An added solid-state sensor precisely detects formaldehyde, while our catalytic filter breaks it down into two safer molecules – carbon dioxide and water.

What is formaldehyde, and where does it come from?

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.

What is HEPA H13?

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.

How often should I replace my filter?

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 odors 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.⁵ The catalytic filter never needs replacing.

What is the cooling functionality of TP09? Is it an air conditioner?

The Dyson Purifier Cool Formaldehyde is both an air purifier and a powerful cooling fan. The machine uses Dyson Air Multiplier™ technology to project a powerful stream of high-velocity, purified air to cool you down quickly.

Do Dyson purifiers capture wildfire smoke?

Yes, Dyson purifiers capture wildfire smoke and other combustion pollutants.⁸

  • 1 In maximum setting. Tested for air projection (DTM 801) and purification coverage in an 81m³ room (TM-003711).
  • 2 Whole machine tested by independent third-party laboratory Airmid (Ireland) in 28.5m³ test chamber pre-conditioned to 20±3C and RH 50±5%. Influenza A (H1N1) aerosolised in the test chamber and airborne concentration observed for the duration of 60 minutes under maximum Fan speed. Achieved 99% efficacy but real life efficacy may differ depending on actual environment and Fan speed. Tested on Influenza A (H1N1) only.
