Costa del Este is an area of corporate towers, hotels, clinics and shopping centers that keeps growing along the bay. Most buildings are modern and closed, with air conditioning that runs continuously, so the indoor air depends entirely on what the system delivers. It is about 7.5 km by road from the Climatiza office, in an approximate calculation.
In a closed building much of the air people breathe goes through the system, so the ducts work without a pause and hold on to the dust they carry. Between the damp climate and the condensation of the unit itself, that dust can encourage mold, and a network that runs all year has few chances to dry out inside.
Data point: At the Tocumen station the mean relative humidity drops to 64.9% in March, the least humid month, and rises to 82.4% in October (ETESA, 1977 to 2010, in Spanish). The EPA recommends keeping indoor air below 60%.
