Pollutants can build up inside your workspace. But you can't always see them.

In fact, indoor air quality can be up to 5x worse than outdoor air quality.4

Frequently asked questions

Your purifying fan's auto mode is designed to manage the air quality without you having to operate the machine – so it's only on when it needs to be. If someone is suffering from allergies or respiratory illnesses, we particularly recommend using your machine's auto mode.

If auto mode is enabled, AUTO will be illuminated on your purifying fan's LCD 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 purifying fan heater will remain idle until pollutant levels rise.

Increasing airflow will create a cooling effect using purified air, so you may find it beneficial to change your purifying fan heater'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.
