Why Qubo Air purifier readings are not the same as the outdoor AQI?

The Air Quality Index (AQI) is a combined score based on several pollutants such as PM2.5, PM10, ozone, carbon monoxide, nitrogen dioxide, and sulphur dioxide. It reflects outdoor city-level air but not the exact mix of pollutants in your home.

Your Qubo Air Purifier shows real-time PM2.5 readings - fine dust particles most harmful to health. Indoor PM2.5 levels drop faster when doors and windows are closed, so your purifier's readings are often lower than outdoor AQI.

Qubo focuses on PM2.5 because it's the most accurate and health-relevant indicator of indoor air quality.

This table shows how PM2.5 concentration levels correspond to Air Quality Index (AQI) values based on the official CPCB (India) standard. Higher PM2.5 levels indicate poorer air quality and greater potential health risks.

Air Quality Category	AQI Range	PM2.5 (ug/m3)
Good	0 - 50	0 - 30
Satisfactory	51 - 100	31 - 60
Moderate	101 - 200	61 - 90
Poor	201 - 300	91 - 120
Very Poor	301 - 400	121 - 250
Severe	401 - 500	251 - 500

Why does my Qubo Smart Air Purifier make noise during operation?

a) Fan speed too high: The noise you hear from your purifier is generated by the motor and fan during operation. Your purifier is designed to operate quietly; however, in silent rooms you may notice some sound. Reduce fan speed or switch to Sleep Mode for quieter performance.

b) Loud in Auto Mode: In Auto Mode, your purifier adjusts fan speed automatically when air quality changes. If you find the noise too high, switch to Sleep Mode or manually select a lower speed.
