Our Mission
Clean air is a human right and PHAN exists to protect it. Public health systems have failed to protect clean air, workers, and the immunocompromised. PHAN is stepping in to build the infrastructure those institutions abandoned. We create open-source, open-data, and open-science tools, coordinate global expertise, support legal action, and push for enforceable clean air policy.
Our mission is to defend public health and clean air as a human right and to build lasting transparent systems that protect people from airborne threats, now and for generations to come.

90% of Long Covid cases come from a "mild" SARS-COV-2 acute infection

School Impact

Schools: ~81 % of classrooms exceed 1,000 ppm CO₂ (i.e. under-ventilated), with median ~1,487 ppm in a 2,444-classroom study - conditions that correlate with 10–20 % declines in cognitive performance.

Economic Impact

Long COVID now imposes ~US$1 TRILLION/year in lost productivity globally (≈ 1 % of global GDP)

Health Impact

The COVID era has already cost the U.S. over US$16 TRILLION when combining lost output, premature death, and long-term impairments.

Labor Impact

~14 % of those with Long COVID failed to return to work within 3 months; >7 % missed >10 days of work in that period.
