Our air quality meter recorded the Gen1 transformed a small room’s air quality from 204 micrograms per cubic meter of PM2.5 to 23 in around 40 minutes. That’s almost twice as long as air ...
Unlike low-cost monitors, which are carried from place to place, static monitors continuously sample and measure the air quality in a particular, urban location. Public places such as busy railroad stations sometimes have active air quality monitors permanently fixed alongside platforms to measure levels of nitrogen dioxide and other pollutants ...
