The air quality indicator never goes up to yellow or red.  How do I know if the sensor is working?

Here are ways to test that the sensor is working properly:

AeraMax™ 90/100/DX5

• Your indoor air is probably clean with no pollutants in it. To verify, place a dry erase marker or hand sanitizer – or any other object emitting a strong smell such as a perfumed item close to the right side of the handle on the back of your air purifier.

• The AeraSmart™ Sensor, located to the right of the handle, will detect the odor after a few seconds and trigger the amber or red level of your AeraSmart™ Sensor Indicator Light.

• If this experiment does not work, verify that the bag has been removed from around your filters and conduct the above experiment again.

• If this still does not work, the AeraSmart™ Sensor of the unit is probably defective. Please call customer service. 

AeraMax™ 190/200/DX55/290/300/DX95 and all AeraMax PRO AM2/AM3/AM4 units

• Your indoor air is probably clean with no pollutants in it.

• To verify, place a dry erase marker – or another object emitting a strong smell such as a perfumed item close to the right side of the machine, by the Fan Speed Indicator.

• The AeraSmart™ Sensor, located on the right side of the air purifier, will detect the odor after a few seconds and trigger the amber or red level of your AeraSmart™ Sensor Indicator Light.

• If this experiment does not work, verify that the bag has been removed from around your filters and conduct the above experiment again.
