Does the job but could do better

Jeffy Duck

The product does the job, humidifies and filters the air without leaving a mess like regular humidifiers, its pretty cool that when you set the fan and humidity controls to automatic and it senses bad air it will automatically run at higher fan speeds and gradually lower as the air quality gets better. Down side is the software response time between the remote control and the unit itself, for example I adjusted the air speed and wanted to adjust himidity control or show a different information in the screen, I'll have to wait about 2 seconds for it can take a different remote command and another possible issue is if you misplaced the remote then controlling the unit is impossible

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.⁵ With a hassle-free Deep clean cycle that  eliminates mineral build-up throughout your machine's water system.

Are Dyson Purifier Humidifiers good for your skin?

Through robost scientific testing, we found that humidified air from the Dyson Purifier Humidfy+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. Thereby, we can confidently say that they help keep your skin hydrated.

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 the signs of dryness, kickstarting the machine to humify the air only when needed. Through Dyson ultraviolet cleanse technology, every drop of water if further exposed to a powerful 275nm UV light that allows for only cleansed water to rehydrate the purified air abck into the whole room.

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.
