Frequently asked questions - Purifier Humidify+Cool Formaldehyde

How does a purifier humidifier work?

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.

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, smoke, odors 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.

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

We've re-engineered our latest purifier humidifier to be fully sealed to HEPA H13 standard.⁹ That, in addition to our advanced filtration, hygienic humidification, and hassle-free Deep clean cycle, differentiate this product from other humidifiers.

What is different about the Dyson Formaldehyde range?

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.⁺ 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.

Do Dyson purifiers capture wildfire smoke?

Dyson purifiers capture wildfire smoke.¹¹

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.³

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 odours that occur through poor maintenance.
