Indoor PM2.5 often tracks outdoor PM2.5 and our hyperlocal AirGradient setup makes this visible. From 1-7 September, indoor PM2.5 closely followed the outdoor pattern, almost hour by hour. But Tuesday was particularly interesting. PM2.5 and CO₂ peaked together. 1/3

Chart shows PM2.5 levels both indoor and outdoors over a period of one week in September. Indoor levels track outdoor levels across the whole week. The monitors used were AirGradient ONE (indoors) and OPEN (outdoors) available from Smart Air UK & EU - www.smartairfilters.co.uk. This chart shows the value of being able to track levels with a hyperlocal outdoor monitor rather than the nearest government station.
