Aqueous solutions containing sodium chloride, sometimes employed during the process of air conveyance system maintenance, serve primarily to address microbial growth and particulate matter accumulation. These solutions, delivered via specialized equipment, can loosen debris and inhibit the propagation of certain biological contaminants within ductwork. For instance, a diluted salt-water mixture might be nebulized into the duct system to target mold spores or dislodge dust adhering to interior surfaces.
The utilization of such formulations in air duct maintenance can contribute to improved indoor air quality by reducing the overall burden of allergens and irritants circulating within a building. Historically, alternative sanitizing agents were more prevalent; however, saline solutions are increasingly considered due to their generally recognized safety profile and reduced risk of chemical off-gassing. This approach can be particularly beneficial in environments sensitive to harsh chemicals, such as hospitals or schools.
