Your smart air purifier monitoring controller can monitor PM2.5, CO2and TVOC concentration.
When paired with LIFAair smart air purifiers, it can automatically control purifier main unit and maintain PM2.5 concentration in a healthy range. It
can also monitor temperature and humidity.
The monitoring controller will monitor air quality. There are six levels: good, moderate, unhealthy for sensitive groups, unhealthy, very unhealthy, and
hazardous. American standards will be more stringent.

The Chinese standard requires PM2.5 level to be below
35µg/m3. American standard requires PM2.5 level to be
under 12µg/m3. It takes about 40 seconds for the value to
stabilize.
3. Press and hold on the controller, press to
select“Purifier Pairing”, then press to confirm.
5. After the pairing is successful, the main unit indicator light
