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 purifying 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 LED display stay on throughout the night?
If you're concerned by the brightness of your purifying fan's LED 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 is on, but the main display turns off after 10 seconds to help avoid sleep disturbance.
How do I know when my purifying fan is in auto mode?
If auto mode is enabled, AUTO will be illuminated on your purifying fan's LED display. When your machine is purifying the air, AUTO will be in white. When the air in the room is clean, it will turn green and your purifying fan will remain idle until pollutant levels rise.
How long should my purifying fan be turned on for?
Your purifying 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.
Where should I place my purifying fan?
Your purifying 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 purifying 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.
