24 de Diciembre belongs to the Panama district and came into being in 2002, when it was split off from Pacora. It borders Tocumen and is made up of neighborhoods such as Santa María de los Ángeles, Vista Hermosa, Monte Rico and Felipillo, with numerous schools and early childhood centers.
Homes, schools and businesses open to the public sit side by side among the neighborhoods, and each uses the air in a different way: a shop that serves customers all day does not run like a house. The area is about 30 km by road from the Climatiza office, in an approximate calculation. Because the equipment and the camera leave the city, the date is set beforehand with whoever manages each place.
Data point: A modeling study by Waring and Siegel (2008) estimated that filters in commercial systems collect a median of 130 g/m² per month, compared with 2.97 in residential ones. It is an estimate, which is why the actual case is inspected.
