This machine is the Bomb!


I purchased this for my hubby’s 66th b-day. He was always complaining about a stuffy nose at night. The first night we kept it going all night. It felt and smelled like we were high in the mountain air! (We live in Sunny Isles FL on the beach, where it is summer all year long.) Needless to say it has not moved from our bedroom. We have now purchased two more. One for the front room and one for the office. They will be here in a few days. So excited! Thank you for making such an incredible machine!

    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

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.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.

What is 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.¹ 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 what are its common sources?

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 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.

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 Dyson Link app.⁴ The catalytic filter never needs replacing.

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

No, TP09 can serve as a fan, which can help cool you. It is not an air conditioner.

Do Dyson purifiers capture wildfire smoke?

Dyson purifiers capture wildfire smoke.9
