Air machine

Air purifiers are fundamentally simple machines—little more than a fan and a filter. Yet a well-designed purifier can capture virtually all airborne allergens, such as pollen and mold spores, as well as bacteria, viruses, and smoke.3An indoor air purifier ensures the filtration of the indoor air, of an enclosed space, which it captures to release a depolluted air. It works in addition to the necessary natural ventilation, if it is possible to open the windows.
