I purchased the Dyson Air Purifier Humidify just last month, and it has already made an extraordinary difference in the climate of my flat. Before acquiring this device, I struggled with dry and stagnant air, but now, my living space feels fresher, more comfortable, and perfectly humidified. The unit itself is sleek and modern, fitting effortlessly into my home’s decor. Operationally, it is exceptionally efficient, allowing me to control and monitor the humidity levels with precision. What truly impressed me, though, is its quiet performance. It works diligently in the background without creating unnecessary noise. Additionally, the air purification feature ensures that the air in my flat remains free of allergens and pollutants, creating a healthy environment for me and my family. The ease of maintenance and user-friendly interface further adds to the overall satisfaction I have experienced. In conclusion, the Dyson Air Purifier Humidify has truly transformed the atmosphere in my flat. I’m not only pleased but genuinely grateful for this investment. It’s a must-have for anyone looking to enhance their indoor air quality and overall comfort at home. Highly recommended!

Frequently asked questions

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.⁹ So what goes inside, stays inside. With a hassle-free Deep clean cycle that eliminates mineral build-up throughout your machine's water system.

What is different about the Dyson Purifier Humidify+Cool Formaldehyde™️ range?

The Dyson Purifier Humidify+Cool Formaldehyde™️ has all of the capabilities found in our Dyson Purifier Humidify+Cool™️ products but goes a step further to detect and destroy formaldehyde.⁺ 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 common sources of it?

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.

Where should I place the purifier humidifier in my room?

Your Dyson Purifier 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. You can select your water hardness with the myDyson app.⁵ Running a Deep clean cycle helps to eliminate odors that occur through poor maintenance.

Do Dyson purifiers capture wildfire smoke?

Dyson purifiers capture wildfire smoke.¹¹

Are Dyson Purifier Humidifiers good for your skin?

Through robust scientific testing, we found that humidified air from the Dyson Purifier Humidify+Cool range results in higher skin hydration over a three-hour period compared to dry air, particularly if the skin was previously exposed to dry environmental conditions. Helps keep your skin hydrated and protects the moisture balance in your skin±​

​ How do Dyson Purifier Humidifiers benefit your skin?

The Dyson Purifier Humidify+Cool range automatically maintains the target level of moisture in the air and with auto mode, scans the air for signs of dryness, kickstarting the machine to humidify the air only when needed. Through Dyson ultraviolet cleanse technology, every drop of water is further exposed to a powerful λ275nm UV light that allows for only cleansed water to rehydrate the purified air back into the whole room.¹⁵​
