Frequently asked questions
Should I change the fan settings in different seasons?
Increasing airflow will create a cooling effect using purified air, so you may find it beneficial to change your purifier fan's speed settings as the temperature changes. For personal cooling in summer, use settings 4-10. In colder periods, enable diffused mode. It projects air through the back of the machine, to avoid unwanted cooling.
Does the LCD display stay on throughout the night?
If you're concerned by the brightness of your purifier fan's LCD display, consider enabling Night-time mode using your remote control or the Dyson Link app. During operation, a small moon icon indicates that your purifier fan is on, but the main display turns off after 10 seconds to help avoid sleep disturbance.
How do I know when my purifier fan is in auto mode?
If auto mode is enabled, AUTO will be illuminated on your purifier fan's LED display. When your machine is purifying the air, AUTO will be in white. When the air in the room is purified, it will turn green and your purifier fan will remain idle until pollutant levels rise.
How long should my purifier fan be turned on for?
Your purifier fan's auto mode is designed to manage the air quality in your home without you having to operate the machine – so it's only on when it needs to be. If you or someone in your home suffer from allergies or respiratory illnesses, we particularly recommend using your machine's auto mode.
Where should I place my purifier fan?
Your purifier fan is engineered to purify single rooms, so you should use it where you spend the majority of your time at home. When placing the machine, make sure there is at least a few feet of clearance on all sides so that the air can circulate effectively.
Should I keep my windows open or closed?
Your purifier fan works most efficiently in a sealed environment – opening the windows can allow more pollutants to enter the air in your home, which means your machine will take longer to work.
