What are PM2.5 filters and why are they effective ...

A PM2.5 filter is a disposable insert that improves a mask's filtration effectiveness, especially against the smallest aerosolized particles. A certified pm2.5 filter used with a fitted cloth mask can block the vast majority of airborne particulates, i ncluding fine aerosols.When evaluating breathable, reusable solutions for everyday use, a pm2.5 filter + mask is one of the most protective ...

Arduino Code | PM2.5 Air Quality Sensor | Adafruit ...

Dec 27, 2017 · Arduino Code. Using the PM2.5 with Arduino is a simple matter of wiring up it to your Arduino-compatible microcontroller, installing the Adafruit PM25AQI library we've written, and running the provided example code. This code will get you started with any Arduino compatible (e.g. Arduino UNO, Adafruit Metro, ESP8266, Teensy, etc.

Abrupt but smaller than expected changes in surface air ...

The COVID-19 lockdowns led to major reductions in air pollutant emissions. Here, we quantitatively evaluate changes in ambient NO2, O3, and PM2.5 concentrations arising from these emission changes in 11 cities globally by applying a deweathering machine learning technique. Sudden decreases in deweathered NO2 concentrations and increases in O3 were observed in almost all cities.
