Amid rising pollution in big cities, real estate companies are launching “Low AQI Homes.” This trend is fast catching up in cities like Noida, Delhi, and Gurugram, where poor air quality has pushed developers to introduce such projects.
What are Low AQI Homes?
These homes are designed in such a way that the air inside remains significantly cleaner than outside. They use advanced technologies like Nordic systems, air filtration, smart ventilation, and low-emission materials. In simple terms, these homes create a clean air zone indoors.
Latest Offerings
Reas estate company, BOOTES Realty has launched Aspire Leisure Valley in Greater Noida West (Techzone 4) and Aspire Silicon City in Sector 76, Noida. The company claims indoor AQI levels below 50.
According to MD Dipak Roy, this is the first time Nordic technology is being applied in residential projects in India. The company has developed an integrated system called FreshAir Pro, designed to maintain indoor AQI below 50 and control CO₂ levels while supplying fresh air and clean water.
Roy also claims that although bringing outside air indoors usually increases energy consumption, their heat exchanger can recover up to 85% of energy, reducing electricity usage. BOOTES is also described as India’s first net-zero real estate company.
Godrej Properties is also offering low AQI houses. Its premium project Godrej South Estate in Delhi features a Centrally Treated Fresh Air (CTFA) system integrated with VRF air conditioning. Nimbus Group has launched The Arista Luxe on the Noida Expressway, also claiming indoor AQI below 50.
How does this technology work?
According to Dipak Roy, the system is a built-in (integrated) mechanism, not a portable device, called FreshAir Pro. It works in two modes:
1. Recirculation Mode: Indoor air is pulled into the system where filters remove dust, hair, and larger particles. IFD technology kills bacteria. Electrostatic filters capture fine particles like PM2.5. Multi-layer filters remove remaining pollutants and gases. Clean air is sent back into the room
2. Fresh Air Intake Mode: When CO₂ levels rise, sensors detect high CO₂ levels and fresh air is brought in through ducts. Air passes through multiple filtration stages. A heat exchanger adjusts temperature to room level clean air is supplied while polluted air is expelled.
How is it different from air purifiers?
Regular air purifiers only circulate indoor air, they do not bring in fresh oxygen. When CO₂ levels rise above 1000 ppm, it can cause fatigue and headaches. Opening windows allows polluted air (PM2.5, dust, gases) to enter. In contrast, this system monitors CO₂, PM2.5, VOCs, and temperature in real timeAutomatically switches modesEnsures continuous supply of filtered fresh air.
In NCR regions, AQI often crosses 500, severely impacting health. Rising cases of asthma, allergies, and respiratory diseases have made people more conscious about indoor air.
According to reports, nearly 2 million deaths occur annually in India due to pollution-related diseases. A study published in The Lancet reported that in 2022, around 1.7 million deaths in India were linked to PM2.5. Pollution reduces life expectancy by 8–10 years.
A growing real estate trend
Experts believe Low AQI homes will soon become mainstream, not just for residences but also for office spaces.
Nithin Kamath has even suggested linking property prices to environmental quality, higher pollution should mean lower property values.
Similarly, property dealer Sandeep Tyagi says buyers increasingly prefer greener, healthier environments. With shrinking green cover and rising pollution in cities, Low AQI homes are emerging as a preferred option for homebuyers.
