Delhi Chief Minister Rekha Gupta on Saturday, 23 May 2026, conducted an on-ground inspection of three indigenously developed air purification technologies deployed across west Delhi, underscoring the government's stated commitment to year-round pollution control rather than seasonal interventions alone.

Context

Gupta was accompanied by cabinet colleague Manjinder Singh Sirsa and BJP MLA Harish Khurana during the review. The Chief Minister framed the exercise as part of a continuous campaign — '365 din swachh hawa aur behtar janswasthya ke liye' (for clean air and better public health 365 days a year) — explicitly distancing the effort from the perception that Delhi's anti-pollution drive is limited to the winter smog season.

Three distinct 'Made in India' devices were inspected during the visit, each targeting a different source or corridor of urban air pollution.

Policy Backdrop

The deployment sits within a longer arc of technological pilots in the capital. Delhi administrations began trialling anti-smog guns as early as 2019–20, while the Graded Response Action Plan (GRAP), introduced in 2017, established the regulatory scaffolding for staged emergency responses to deteriorating air quality across the Delhi-NCR region. The Commission for Air Quality Management, a statutory body set up in 2021, coordinates these efforts across state boundaries.

The current BJP-led Delhi government has placed emphasis on indigenously manufactured equipment, aligning the pollution-control push with the national Make in India initiative launched in September 2014. All three devices inspected on Saturday are described as domestically produced.

The Three Technologies

The first system, the STR 101 Filterless Air Purifier, comprises 21 devices installed along Sat Guru Ram Singh Marg. According to the post, the advanced self-cleaning system treats approximately 3 lakh litres of air per hour, targeting smoke, dust, PM2.5, PM10, and other harmful pollutants.

The second is an EV-mounted Anti-Smog Gun deployed in the Kirti Nagar and Mayapuri areas. Described in the post as a zero-emission moving anti-smog system, it is designed to reduce road dust and pollution while creating clean-air corridors for improved visibility and breathing comfort.

The third device, PAWAN III, is installed near Kirti Nagar Fire Station and is designed to capture and treat vehicular pollution at source level. The post states that field trials recorded a reduction of approximately 29 per cent in particulate pollution.

Stakeholders and Impact

The deployments are concentrated in west Delhi's Kirti Nagar and Mayapuri belt — a mixed industrial and residential zone where vehicular traffic and industrial activity combine to produce elevated pollution loads. Residents, daily commuters, and workers in the area stand to be the most immediate beneficiaries if the pilots scale.

The year-round framing signals a political as well as administrative shift: the BJP government appears keen to demonstrate that anti-pollution action is not reactive to winter emergencies but is being built into the city's permanent infrastructure.

What's Next

The critical test will come during the 2026–27 winter season, when Delhi's air quality typically deteriorates sharply due to a combination of stubble burning in neighbouring states, falling temperatures, and reduced wind speeds. Performance data from these field deployments will determine whether the cabinet decides to expand the technology to additional corridors or industrial clusters across the capital. Any such expansion decision would also signal how seriously the administration intends to pursue source-level, year-round intervention as a complement to emergency-response frameworks like GRAP.
