Information

The input trace substance changes from 20 µg/m³ (1.546e-8 kg/kg, assuming the air density of 1.293 kg/m³) to 100 µg/m³ (7.734e-8 kg/kg) during the 2 years period (63072000 seconds).

At around day 355, day 547, and day 696, the mass of the captured contaminant become more than the maximum mass of the contaminant that can be captured (1.0 kg). The filter thus was replaced and the captured mass was replaced to 0.
