Overview

• The DPCC launched a three-day survey at Nehru Park on Sunday to gather visitor feedback on installing 150 outdoor air purifiers.
• Results are due Tuesday and will determine whether the pilot proceeds under the city’s Environmental Action Plan.
• Each nine-foot-tall purifier filters PM2.5, covers about 600 square metres and costs around ₹5 lakh.
• The project will run as a CSR partnership with private firm Umeandus, pending clearance from the New Delhi Municipal Council before installation.
• Officials hope to apply lessons from the 2023 closure of two ineffective smog towers to this pilot, with potential replication in busy markets.
