IAQ (Indoor Air Quality): IAQ refers to the quality of air within a building or other enclosed space. Poor indoor air quality can be caused by a number of factors, including inadequate ventilation, bad air circulation, and the presence of pollutants such as pesticides, dust mites, mold, and viruses. Good IAQ is essential for maintaining the health and wellbeing of any building’s inhabitants. It can be improved with regular cleaning and maintenance, as well as making sure the space is well ventilated and has access to fresh air.
