There are many types of businesses that suffer from poor air quality related to gases and odors. In gyms, schools, offices, production facilities, and healthcare facilities, the indoor air can often be contaminated by odors from the people using the facility. Odors can also be a sign of more serious concerns, such as off-gassing. Off-gassing occurs when newly manufactured items like paints, carpets, flooring, certain textile treatments, mattresses, furniture, and cabinets release volatile organic compounds (VOCs). Some of these VOCs, such as benzene and toluene can be toxic and cause serious health issues.
