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 �f¢â�?s¬â�,� fine dust particles most harmful to health. Indoor PM2.5 levels drop faster when doors and windows are closed, so your purifier�f¢â�?s¬â�?z¢s readings are often lower than outdoor AQI.
Qubo focuses on PM2.5 because it�f¢â�?s¬â�?z¢s the most accurate and health-relevant indicator of indoor air quality.
This table shows how PM�f¢â�,�šâ�,�š.�f¢â�,�šâ�,�¦ concentration levels correspond to Air Quality Index (AQI) values based on the official CPCB (India) standard. Higher PM�f¢â�,�šâ�,�š.�f¢â�,�šâ�,�¦ levels indicate poorer air quality and greater potential health risks.
