Achieving your manual humidity setting

If your machine’s LCD shows this icon, you're being advised to manually increase the airflow to eight or above. This may help you to reach your desired humidity level faster.

Other steps that can help include:

• Moving your machine away from air vents

• Keeping your machine away from high traffic doorways

• Using a lower setting for heating or air conditioning units.

Frequently asked questions

How often does the filter need to be changed?

The Combi filter needs to be changed after 12 months, based on 12 hours’ use a day.

How long can my machine humidify for?

With a full tank, your machine can humidify continuously for up to 36 hours in fan mode 1.

Can I switch off humidification?

Yes. The machine works as a purifier humidifier, or just a purifier 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™️ app¹.

Will the humidifier overheat if it runs out of water?

No. It has a sensor to detect if it’s out of water. The screen alerts you to refill your water tank when needed.

Can multiple users share the same machine?

Yes, an unlimited number of users can use a single machine. The machine will only ever choose the most recent update. For example, if more than one person was updating the scheduling, the most recent change will be the one the machine progresses with.

Where should I place my machine?

Your machine 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.
