AirOK Technologies is an Indian cleantech manufacturer specializing in indoor and outdoor air purification systems. The company was founded by Deekshith Vara Prasad, Yasa Pavan Reddy and Vanam Sravan Krishna, three former IIT Madras students, and was incubated at IIT Madras.
AirOK has developed a patented air filter designed to remove air pollutants from indoor and ambient environments, marketed under the EGAPA name. Its Vistar range of smart air purifiers uses the EGAPA Comfort filter and offers Wi-Fi and cloud connectivity, with users able to control functions through a mobile app. The filters are designed for low maintenance, with replacement intervals of 8 to 12 months depending on carbon dioxide concentration levels.
Designed primarily for commercial use, AirOK targets the hospitality, real estate, food processing and manufacturing sectors as its primary markets, and the company has also worked with national distribution partners to expand into the government sector across India. Its product range has expanded to include filtration products used in automotive and pharmaceutical industries, HVAC systems, and gas turbines, alongside data center air quality solutions and outdoor pollution capture systems. The company operates from a registered base at the IIT Madras Research Park in Chennai, with an additional operational office in Gurgaon, Haryana.
SDG 3 is directly relevant because AirOK’s core products are designed to remove particulate matter, volatile organic compounds, microbes and gaseous pollutants from indoor air, addressing a documented public health risk in Indian cities.
SDG 9 applies because the company’s EGAPA filtration technology was developed through applied research originating in an academic engineering environment (IIT Madras) and represents an indigenous industrial innovation in the filtration equipment sector.
SDG 11 is relevant because AirOK’s commercial and outdoor air purification systems are deployed to improve air quality in urban and institutional settings, including offices, hospitals, hotels and public infrastructure, contributing to healthier and more livable city environments.
AirOK’s approach centers on its proprietary EGAPA (Efficient Granular Adsorbent Particulate Arrester) filtration technology. EGAPA filters are designed to remove up to 99.7% of harmful indoor air pollutants and are described as targeting the destruction of pollutants including VOCs, bacteria, mold, viruses and allergens through a single filtration stage. The company has tested filtration efficiency using nutrient agar plates capable of supporting bacterial and fungal growth, reporting clearance of 90% of airborne microbes in a 144 square foot test area over a three hour run.
Rather than applying a single generic filter design across all use cases, AirOK’s stated approach is to identify and target India’s specific pollution mix, from particulate matter to chemical contaminants and biological agents, on a sector by sector basis. This has resulted in differentiated product lines for residential (Bliss), commercial (Vistar, Vistar Pro, Vistar Pro Max), industrial (HVAC filtration), and outdoor (Pollution Seizure) applications. Higher-capacity commercial units use two large EGAPA filters to service spaces up to 2,000 square feet, while smart sensor integration is used across the Vistar range to automate purifier activation based on real-time pollution readings. The company also engages in ongoing product development, including purifiers adapted for automotive and kitchen environments.
AirOK operates in India’s indoor air quality equipment segment, competing primarily on filtration technology rather than price. The company positions itself as a provider of air quality solutions built around a patented filter platform, supported by a team with an environmental engineering background. Its customer base spans both individual consumers and industrial sectors including automotive and pharmaceuticals, with commercial deployments concentrated in hospitality, real estate, healthcare and IT office environments. Industry data places AirOK among more than 130 tracked competitors in the air quality management space, indicating it operates within a broader field of domestic and international filtration providers rather than a narrow niche
AirOK Technologies represents a category of Indian cleantech manufacturer that emerged directly from academic research, translating an IIT Madras engineering project into a commercial filtration business. Its significance lies less in scale and more in the specificity of its approach: rather than adapting imported air purifier designs, the company has built sector-differentiated products for healthcare, hospitality, industrial and outdoor use cases, reflecting a systems-level view of India’s varied pollution sources.
The company’s early institutional backing, including incubation support and investment from an established consumer goods group, lent it credibility in a market where many entrants rely on generic hardware. Its expansion into HVAC, automotive and data center filtration suggests an attempt to diversify beyond standalone consumer or office purifiers into more technical, recurring B2B relationships.
At the same time, publicly available financial and operational data point to a company operating at modest scale, with revenue in the sub $1.5 million range and a small workforce, more than a decade after founding. Claims around filtration efficiency and patent status appear primarily in company-sourced materials, with limited independent verification available. Procurement teams evaluating AirOK should weigh its technical differentiation against the availability of third-party performance validation and long-term service infrastructure.
