Dyson purifier humidifiers are tested beyond the industry standard

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.

Only a Dyson is fully sealed to HEPA H13 standard⁴

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.

Destroys potentially harmful bacteria

Dyson Ultraviolet Cleanse technology exposes every drop of water to a powerful λ275nm UV light. This kills 99.9% of bacteria in the water.² Cleansed water is then evaporated by the biostatic 3D air mesh, before hygienic, humidified air is projected throughout the room.⁶

To humidify your environment, hygienically

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.

Frequently asked questions

How does a purifier humidifier work?

The Dyson purifier humidifier senses and captures pollutants and measures the correct level of moisture in the air – automatically. Then, it projects purified and hygienically humidified air around the whole room, cooling you when needed.

Should I use a purifier humidifier all year round?

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, pollen, smoke, odours and pet allergens. You can also use the purifier humidifier when sleeping, on night mode.

What is new about the Dyson purifier humidifier and how is it different to other purifier humidifiers?

We've re-engineered our latest purifier humidifier to be fully sealed to HEPA H13 standard.⁴ With a hassle-free Deep clean cycle that eliminates mineral build-up throughout your machine's water system.

Where should I place the purifier humidifier in my room?

Your Dyson Pure Humidify+Cool™ is engineered to purify and humidify single rooms, so you should use it where you spend the majority of your time at home. When placing the machine, make sure there's at least a few feet of clearance on all sides, so that the air can circulate effectively. Close doors and windows and place away from air vents. 

Can I switch off humidification?

Yes. The machine works as a purifier humidifier, or just a purifying fan. 

How often should I run a Deep clean cycle?

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. Running a Deep clean cycle helps to eliminate odours that occur through poor maintenance.
