Top notch purifier

Richard0211

Been a big fan of Dyson product for many years... and I would say this new Dyson Purifier does not disappoint. It has amazing features, it blows cool and fresh air I'm using it in 4 or 5 and it's perfect already, I can't imagine using it on the highest level 10. The remote is top both plus the Dyson app. You can actually use it with Alexa or Siri For voice commands.

Air valve motor

The valve mechanism is driven by a brushless stepper motor, to allow remote actuation and switching between Backward airflow mode and Fan mode.

Air Multiplier technology

Projects a long-range stream of smooth air to reach every corner of the room. No need for blades.

PTC plates

Air circulates between the plates and external casing, to heat the air as it leaves the machine.

Formaldehyde sensor

Solid state electrochemical cells precisely detect formaldehyde for the lifetime of the machine.

Gas and particulate sensors

Measures and detects particles and volatile organic compounds in the air.

Removes allergens and pollutants

360° HEPA H13 filter has 9 meters of borosilicate microfibres, pleated over 200 times, to trap particles as small as allergens and bacteria.

Destroys formaldehyde

Selective catalytic oxidization destroys formaldehyde released from household items, continuously breaking it down into water and CO2.

Captures gases and odors

Activated carbon filter removes gases such as benzene and NO2.

Dyson purifier hot+cool formaldehyde purifying a large living space

Powerful circulation to purify the whole room

Only Dyson purifiers have Air Multiplier™ technology to draw in distant pollutants and project purified air throughout the room.²

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.

  • Graphic comparison of CADR test v Dyson test

    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.

  • Graphic comparison of CADR test v Dyson test

    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.

Pollutant sources in a living space and kitchen

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.

Common household pollutants

  • Pollen and allergens

    PM10

  • Bacteria

    PM5.0

  • Industrial emissions

    PM2.5

  • Ultrafine particles

    PM0.1

  • Formaldehyde (HCHO)

    Carpets, rugs, and flooring

  • Odors

    Household fumes and cooking

  • Benzene and VOCs

    Cleaning products and candles

  • Nitrogen dioxide

    Gas stoves and car exhausts

Senses and reports, automatically

Four sensors, including a solid-state formaldehyde sensor, interact with our unique algorithm to precisely diagnose, display and react to your air quality.

Captures and destroys with advanced HEPA filtration

The HEPA+Carbon filter captures gases and 99.97% of particles as small as 0.3 microns. Our catalytic filter continuously destroys formaldehyde.

Air purifier catalytic tunnel

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

Fully sealed air purifier

Fully sealed to HEPA H13 standard

To prevent pollutants from leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier.³ So what goes inside, stays inside.

Features

  • Image showing powerful, cooling airflow

    Cools you when needed

    Projects over 77 gallons of air a second for cooling airflow.

  • Someone changing their filter

    Heats when needed

    Air Multiplier™ technology projects purified, heated air throughout the room.² Once your target temperature is reached, heating automatically stops.

  • Purified air exiting the back of the purifier

    Backward airflow. Purifies without cooling you.

    Airflow is diverted through the back of the machine, maintaining effective purification without cooling you.⁴

  • Someone changing their filter

    Easy filter care

    The catalytic filter never needs to be replaced. We recommend replacing the HEPA+Carbon filter when you're alerted by the Dyson Link 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.

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. 

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.⁵ The catalytic filter never needs replacing.

Why can’t I control the temperature or activate heating via the Dyson Link app?

This machine is compliant with safety standard UL 1278, as required by the US government. For this reason, heating and temperature control are not available in the Dyson Link app. Please use your machine’s remote control instead.
