  • Owner's Manual & FAQs

    Question: Why did my Air Purifier suddenly turn on a higher setting?

    Answer: Check if your Air Purifier is set to Auto Mode. If it is, the unit may have sensed a higher level of VOCs and has adjusted the cleaning level accordingly to help reduce them.

    Question: The Air Quality Indicator is constantly changing colors once I turn it on, is this normal?

    Answer: Yes, your air purifier is equipped with a VOC sensor, when the unit is turned on, the Air Quality Indicator will run between green, amber and red for 30 seconds as it calibrates and stop at the respective color based on the air quality/VOCs level detected by the sensors.

    Question: Why is the Filter Indicator Light illuminated after replacing the filter?

    Answer: The Filter Reset Light(s) need to be reset after the filter(s) have been replaced. See instructions on how to reset your filter light in your Owner's manual.
