Detects and destroys formaldehyde¹
Dyson's most advanced filtration system combines a precise, solid-state formaldehyde sensor with a unique catalytic filter that continuously destroys formaldehyde.¹ A filter removes gases and odors and a HEPA filter captures 99.97% of particles 0.3 microns in size. And Dyson purifiers have powerful Air Multiplier™ technology to purify the whole room.²
Dyson Purifier Cool Formaldehyde™ TP09 (White/Gold)
Senses and reports, automatically
Integrated sensors constantly analyze your air, while our unique algorithm cross-checks data every second. It diagnoses pollutants at a molecular level, displaying live results on the LCD.
Captures gases and ultrafine particles
The HEPA filter captures 99.97% of particles 0.3 microns in size. An additional filter removes odors and gases including VOCs.
Destroys formaldehyde, continuously
The Dyson catalytic filter continuously traps and breaks down formaldehyde molecules¹ into water and CO₂. And it never needs replacing.
Purifies the whole room
Only Dyson purifiers have Air Multiplier™ technology. It generates the circulation power to draw even distant pollutants into the machine, projecting purified air throughout the room.²
Fully sealed to HEPA H13
In our latest purifiers, it's not just the filter that meets HEPA H13 standard, it's the whole machine.³ So what goes inside, stays inside.
Precisely detects formaldehyde
Our latest purifiers use a solid-state sensor to detect formaldehyde molecules 500 times smaller than 0.3 microns and maintains precision for the lifetime of the machine.
Cools you when needed⁵
Projects over 77 gallons of air a second for cooling airflow.
Backward airflow mode
Diverts airflow through the back of the machine. To purify, without cooling you.
Now 20% quieter
Acoustically engineered to reduce turbulence, so it's 20% quieter than the previous model.
Control and monitor your air quality from anywhere using the MyDyson app.⁴
Control it hands-free with compatible voice services. Works with Amazon Alexa, Apple Siri, and Google Home.⁴
Oscillates up to 350 ̊
Adjustable oscillation projects purified air around the whole room.
For lighter sleepers. Monitors and purifies using the quietest settings, along with a dimmed display.
Easy filter care
The filter is quick and easy to change. With automatic filter-life notifications on the LCD or MyDyson app.
Curved and magnetized to store neatly on top of the machine.
Energy Star Certified
Parent Tested Parent Approved
Awarded the PTPA seal of approval. The seal of approval families trust.

Cleaner air, cleaner home: how to maintain a healthier space during home renovations
Moving and home makeovers involve new furniture and paint, which could add to the levels of a potentially harmful pollutant called formaldehyde in the home. Here's how to maintain a healthier space during moves and renovations.
Formaldehyde: the invisible indoor pollutant
Although the smell of new paint might fade over time, the emission of potentially harmful gases, such as formaldehyde, can persist. Pollutants like these can continuously ‘off-gas’ for a number of years – but what exactly is formaldehyde and why is it in our homes?
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.³ 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. This machine is also 20% quieter than previous models, achieving lower sound output without any compromise to purification performance.
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.¹ 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.
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 liter of air. Dyson filters also capture 99.97% of particles down to 0.3 microns in size including common pollutants such as allergens, bacteria, viruses, pollen, and mold 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 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 Dyson Link app.⁴ The catalytic filter never needs replacing.
No, TP09 can serve as a fan, which can help cool you. It is not an air conditioner.
