👉 ISA (Indoor Smog) Fumes refer to a mixture of pollutants that can degrade indoor air quality, primarily consisting of volatile organic compounds (VOCs), particulate matter, and other harmful substances like carbon monoxide, nitrogen dioxide, and ozone. These fumes are often produced by common household items such as paints, cleaning agents, furniture, carpets, and even personal care products. When these chemicals evaporate indoors, they can accumulate, leading to poor air quality that can cause respiratory issues, headaches, and other health problems. Proper ventilation and using low-VOC alternatives can help mitigate the effects of ISA fumes.
