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 (µg/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

Replace the filter-

We recommend replacing the filter once every year for the best performance and avoiding any damage to the product.

a) Fan speed too high:The noise you hear from your Qubo Smart Air Purifier is generated by the motor and fan during operation. Your purifier is designed to operate quietly; however, in certain situations—such as while sleeping or in a silent room—you may notice some sound.
If this happens, try reducing the fan speed manually or switching to Sleep Mode for quieter performance.

b) Qubo Smart Air Purifier gets too loud in Auto Mode: When in Auto Mode, your Qubo Smart Air Purifier uses advanced sensors to detect even slight changes in air quality and automatically adjusts the fan speed to restore clean air as quickly as possible.
If you find the noise level too high, you can manually set the fan speed to a lower level or switch to Sleep Mode for near-silent operation.
