Gurgaon, Haryana, May 2025:
As air quality in Indian cities continues to worsen, a Gurgaon-based clean air technology company is drawing attention to a problem that most urban families do not see, the air inside their own homes.
AirOK Technologies, founded by IIT Madras alums with backgrounds in environmental engineering, has been working on indoor air quality for several years. The company’s core technology, the patented EGAPA® air filter, was developed after extensive research into how air pollutants behave in indoor and ambient environments.
The timing of this work could not be more relevant.
India is home to several of the world’s most polluted cities. While conversations around outdoor pollution have grown louder in recent years, indoor air quality has received far less attention. Yet the data tells a concerning story. People spend roughly 80 to 90 percent of their time indoors, at home, in offices, and in schools. During that time, indoor air can accumulate fine particulate matter, dust, allergens, bacteria, volatile organic compounds (VOCs), and mold. These pollutants do not need to be visible to cause harm.
Fine particles classified as PM2.5 are among the most dangerous. They are small enough to bypass the body’s natural defenses and reach deep into the lungs. Prolonged exposure is associated with respiratory irritation, allergies, chronic fatigue, disrupted sleep, and, in serious cases, long-term lung damage.
For families with young children or elderly members, the risks are even higher.
AirOK Technologies was built specifically to address this gap. The EGAPA® filter at the heart of its air purifier range is designed to remove up to 99.7 percent of harmful indoor air pollutants. This includes particulate matter, toxic gases, carbon dioxide, VOCs, bacteria, mold, viruses, and allergens. Independent third-party laboratory testing confirms these results. In one certified test, EGAPA® filter technology reduced indoor air contaminants to undetectable levels within 90 minutes.
The technology has also been tested in more demanding real-world conditions. AirOK air purifier devices were assessed in pediatric intensive care units at a leading children’s hospital, with results showing a significant reduction in airborne bacteria during operation. In a separate laboratory test using nutrient agar plates, the standard method for detecting microbial growth, the AirOK air purifier cleared 72 percent of bacterial and fungal colonies within two hours and 90 percent within three hours in a 144 square feet space.
These are not marketing claims. They are verified outcomes from independent testing environments.
Beyond the technology itself, the company has taken a practical approach to making clean air accessible. The EGAPA® filter is designed to be affordable and long-lasting. It costs approximately 3 times less than comparable commercial air filters available in the Indian market, translating directly into lower maintenance costs for households.
AirOK’s product range is also designed for how Indian families actually live. The Vistar series air purifiers are Wi-Fi enabled and connect to the AirOK Smart App, providing users with real-time indoor air pollution monitoring and fully automated air filtration from their phones. The purifiers feature smart sensing that adjusts operation based on current air quality, cutting energy use without compromising performance.
The company operates on a Make in India foundation. All products are developed domestically, with research and design work done in-house. AirOK holds patents on its core filtration technology and continues to invest in R&D to improve performance across different urban environments.
For Indian consumers who have grown accustomed to filtering their water before drinking it, the company draws a direct parallel. Indoor air quality deserves the same level of attention and care. A home that filters its air is no longer a luxury. Given current pollution levels in major cities, it is fast becoming a basic health decision.
AirOK Technologies products are available on its official website, airoktech.com, where the company also offers subscription plans for households looking for a more affordable entry point.
