Arraiján is the seat of the district of the same name, in West Panama, on the west bank of the Canal’s Pacific entrance. It is described as a commuter city for the capital, and in its corregimiento the Pan-American Highway, the Arraiján-La Chorrera Highway and the Centenario Road meet.
Residential projects have made several of its localities grow, and that calls for looking at each place according to its use: a shop open to the public collects dust differently from a home. Arraiján is about 26 km by road from the Climatiza office, in an approximate calculation. Because the equipment and the camera leave the city on roads with heavy traffic, each visit is agreed beforehand with the management.
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.
