2.5 is particulate matter 2.5 microns or smaller, the fine soot that is
so devastating to human health, the particles so small that they lodge
deep in your lungs, which have difficulty removing them.
No reading if it is raining – the rain washes out the particles.
L’WHNA is the first non-governmental entity in NYC to own its own PM 2.5 air monitor.
People in the community requested John Culpepper to come downtown and do a reading.
You are welcome to come and see how this is done.
