Dyson Purifier Cool Formaldehyde™ TP09 (White/Gold)
We test beyond the industry standard. For real living spaces.
Dyson engineers designed the POLAR test to challenge the industry standard test methods - measuring purification, sensing, and circulation to ensure the whole room is purified properly.
-
Some CADR methods do not measure purification performance in a realistically-sized room.
In this 28.5m³ room, one fan mixes the air before the test, and another circulates air during the test. Only one sensor measures air quality.
-
Dyson's POLAR test goes further to measure purification throughout a realistically-sized room.
In this 81m³ room, there are no fans except the air purifier with nine different sensors to measure even-room air quality.
Poor air quality isn't just a problem outside.
It's a problem inside too.
From pets and flowers, to sprays and stoves, our homes can trap pollutants in the air. That's why Dyson purifiers automatically sense and remove them.

Destroys formaldehyde¹ in billions of catalytic tunnels
Dyson's unique catalytic filter continuously traps and converts formaldehyde into water and CO₂. And it self-regenerates, so it never needs replacing.¹

Features
-
Backward airflow. Purifies without cooling you.
Airflow is diverted through the back of the machine, maintaining effective purification.
-
Cools you when needed⁴
Projects over 77 gallons of air a second for cooling airflow.
-
20% quieter
Acoustically engineered to reduce turbulence, so it's 20% quieter than the previous model.
-
Easy filter care
The catalytic filter never needs to be replaced. We recommend replacing the HEPA+Carbon filter when you're alerted by the MyDyson app or every 12 months, whichever comes first.
-
Night mode
For lighter sleepers, it monitors and purifies using the quietest settings along with a dimmed display.

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.² 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 filtration effectiveness for specific sizes of airborne particles. HEPA H13 is a filter with 99.95% removal of the specific particle size that most readily makes it through that specific filter. Dyson filters also capture 99.97% of particles down to 0.3 microns in size, including common pollutants such as allergens, dust, and smoke particulates.
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.
No, TP09 can serve as a fan, which can help cool you. It is not an air conditioner.
