New York City expands response to dangerous heat and worsening air quality
New York City expanded its response to dangerous heat and worsening air quality on July 15, 2026, including a broad distribution of free KN95 masks through public sites across the five boroughs.
The masks were made available at more than 200 locations operated by the New York Public Library, Queens Public Library and Brooklyn Public Library. They were also available at all NYPD precincts, nine FDNY firehouses and four major transit hubs.
The announcement came from Mayor Zohran Mamdani’s administration and described the effort as a health-protection measure for New Yorkers facing summer heat and air-quality risks.
Where masks were available
The library distribution network included locations in each of the city’s three public-library systems: the New York Public Library, Queens Public Library and Brooklyn Public Library. The city said more than 200 library sites participated.
In addition to libraries, every NYPD precinct was listed as a mask-distribution location. The city also identified nine FDNY firehouses and four major transit hubs where masks were available.
The announced network paired neighborhood-based sites, such as libraries and precincts, with transit locations intended to provide another point of access for people moving around the city.
Agencies and partners involved
City agencies and partners coordinated the distribution. The city identified the NYC Department of Transportation, the New York City Economic Development Corporation, NYC Aging and local council members as participants in the effort.
The Mayor’s Office did not state how many masks had been distributed when it issued the announcement. It also did not specify how long the expanded response or mask availability would continue.
Who the response is meant to protect
The city presented the response as a measure to help protect residents confronting dangerous summer conditions. Heat and degraded air quality can create immediate health concerns, particularly for older adults, people with respiratory illness, outdoor workers and people without reliable cooling or clean indoor air.
The announcement did not provide a borough-by-borough account of air-quality conditions. It also did not claim that the mask distribution would eliminate heat-related illness or improve citywide air quality.
For now, the confirmed next development is the availability of free KN95 masks at the listed public locations. The city’s July 15 announcement did not set out a further deadline or a timetable for the response.
