We have indoor air quality monitors and purifiers to manage indoor air, but even the most intelligent domestic devices cannot inspect all the air pollutants present in our indoor spaces, so I thought it was about time to send a filter from the main air purifier to a laboratory for analysis in order to identify all the pollutants that have been present in my house.
