Increasing the airflow will create a cooling effect with fresh air. Therefore, as the air temperature changes, it may be beneficial to change the speed setting of your heater-enabled air cleaner. In summer, use speed settings 4-10 for your personalized cooling needs. In colder periods, activate the diffusion mode. In this mode, the air is distributed from the rear of the machine to prevent unwanted coolness.

If the LCD screen light of your heater air purifier bothers you, you can activate Night mode using your remote or the Dyson Link mobile app. A small moon icon indicates your heater air purifier is on. The main screen turns off after 10 seconds to avoid interrupting your sleep.

When Auto mode is activated, AUTO appears on the LCD screen of your air cleaner with heater. While your machine is cleaning the air, AUTO appears in white. When the air in the room is cleaned, the color changes to green and your air cleaner with heater will be idle until the pollutant level in the air rises.

The Auto mode of your heater-enabled air cleaner is designed to manage the air quality in your home without you having to control the machine - so your machine will only run when it's needed. If you or anyone in your household has allergies or respiratory diseases, we strongly recommend that you use your machine in Auto mode.

Your heater air cleaner is designed to clean the air of a single room. That's why we recommend using your air purifier in a room where you spend most of your time. When positioning the machine, ensure that there is a clearance of at least 1 meter around the machine so that air can circulate effectively.

Your heater-enabled air cleaner works most efficiently in a closed environment – opening the windows allows more pollutants to enter the air in your home, which means your machine will have to run longer.

Based on 12 hours of use per day, the HEPA+Carbon filter should be replaced every 12 months. The catalytic filter is permanent, it does not need to be changed.
