Closed and poorly ventilated spaces lead to the appearance of mould, fungi and other contaminating factors that remain in the closed environment. These, in turn, mix with particulate matter resulting from the natural wear and tear of the materials from which the warehouse or storage facility is constructed, resulting in a cloud of toxic air for those entering and exiting these spaces. A system of air purifiers strategically placed throughout your offices, and within warehouses, can serve as a barrier against the inconvenience caused by stale air.
