Dyson Purifier Humidify+Cool Formaldehyde™ PH04 (Nickel/Gold)
Improve the air quality inside your home The air in an average home can be up to five times more polluted than the air outside.⁷ On top of this, heating and air conditioning can dry out the air. Fortunately, we have a solution to both.
The Dyson purifier humidifier senses and captures pollutants and measures the current level of moisture in the air - automatically. Then, it projects purified and hygienically humidified air around the room³, cooling you when needed.
Yes, to get the best results, a purifier humidifer should be used all year round. To help combat dry air from central heating and air conditioning, and capture pollutants such as dust, smoke, odours and pet allergens. With pollen more present in summer, and pollutants such as formaldehyde emiting from furniture and flooring, there is benefit to using all year round. You can also use the purifier humidifier when sleeping, on night mode.
We've re-engineered our latest purifier humidifier to be fully sealed to HEPA H13 standard.⁴ That, in addition to our advanced filtration, hygienic humidification, and hassle-free Deep clean cycle, differentiate this product from other humidifiers.
The Dyson Purifier Humidify+Cool Formaldehyde 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. Common sources of formaldehyde could be: 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.
Dyson purifiers capture wildfire smoke.9
Dyson purifiers draw pollutants, such as pollen, dust, allergens and smoke, from every corner of the room and Air Multiplier™ technology projects purified, humidified air throughout the room.³
We test our purifier humidifiers in a room size of 81m³, with nine sensors that continuously measure air quality. Some other manufacturers use a small 28.5m³ chamber, with only one sensor and a fan to boost circulation.

Four sensors constantly monitor your air, including a lifetime solid-state formaldehyde sensor. Our unique algorithm diagnoses pollutants at a molecular level – reacting to purify and humidify before displaying live air quality in real-time reports. You can use the MyDyson app to do this.

A HEPA filter captures 99.97% of particles 0.3 microns in size, a filter removes gases and odors, and a catalytic filter destroys formaldehyde.¹
Dyson's unique catalytic filter continuously traps and converts formaldehyde into water and CO₂, in billions of catalytic tunnels.

To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier humidifier.⁴ So what goes inside, stays inside.
Central heating and air conditioning units can contribute to dry air developing in the home, which can cause dehydration. The Dyson purifying humidifying fan automatically maintains the target level of moisture in your air with an invisible stream of evaporated water, and no mist – for a more comfortable environment.

Yes. The machine works as a purifier humidifier, or just a purifying fan.
This depends on the water hardness where you live. The machine prompts you to run the cycle once a month in hard water areas. It prompts you less often in softer water areas. You can select your water hardness with the Dyson Link app. Running a Deep clean cycle helps to eliminate odours that occur through poor maintenance.
