AQI (Air Quality Index) — What Homebuyers Need to Know

AQI stands for Air Quality Index, a standardized numerical scale used worldwide to communicate how clean or polluted the outdoor air is. In India, the Central Pollution Control Board (CPCB) monitors AQI across cities, measuring pollutants including PM2.5, PM10, NO2, SO2, CO, and Ozone.

How AQI is Measured

The AQI scale in India runs from 0 to 500. An AQI of 0-50 is classified as "Good," meaning the air poses little or no health risk. Between 51-100 is "Satisfactory." From 101-200, air quality is considered "Moderate" to "Poor." Readings above 200 are classified as "Very Poor," and anything above 300 is "Severe" — hazardous to everyone, not just sensitive groups.

Delhi NCR regularly records AQI levels between 200 and 500 during winter months (October to February). Even during summer, the region rarely sustains readings below 100 for extended periods. This chronic exposure to poor air quality has made AQI a critical factor for homebuyers.

Why AQI Matters When Buying a Home

Prolonged exposure to high AQI levels is linked to respiratory diseases, cardiovascular problems, cognitive decline, and reduced life expectancy. For children and the elderly, the health impacts are even more severe. When you purchase a home, you are committing to breathing that location's air for years or decades.

This is why AQI-managed residences have emerged as a category in Indian real estate. Projects like Fab Luxe Residences by Forbes Global Properties engineer their campuses to actively reduce AQI levels through outdoor mist corridors, anti-pollution sprays, microforests, and indoor Fresh-Air Systems with PM2.5/PM10 filters in every room.

What is AQI-Managed Living?

AQI-managed living means a residential project has invested in infrastructure to actively monitor and improve air quality — both outdoors across the campus and indoors within individual apartments. This goes far beyond portable air purifiers. It includes campus-level interventions like mist-cooling corridors, anti-dust pavements, oxygen parks, and botanical belts, along with apartment-level fresh-air supply systems that deliver filtered outdoor air (not recycled indoor air) into every room.

The distinction between recycled air (standard AC) and filtered fresh air is critical. Standard air conditioning recirculates the same stale indoor air. Fresh-air systems bring in outdoor air through industrial filtration, ensuring continuous ventilation with clean air.
