Ventilation was never a concern in the past because we were getting the optimum amount of fresh air to survive. With more high-rise buildings and commercialization, people started spending 90 percent of their time indoors, resulting in the building of tighter duct systems to save energy. This raised concerns about air contaminants indoors. Hence, the need to ensure there is an excellent indoor air quality.

Growing concern about energy costs, security issues, noise pollution, and dirty air from outside have led to more significant concerns for residents. Studies confirm the fact that human exposure to indoor air pollutants may be higher than outdoor levels.
Many people complain regarding building-related health concerns and may have developed building-related illnesses. This does not mean immediate changes required in building practice, but the standard expectation of residential ventilation has been set. Now that it is widely known that indoor air quality can be worse than outside, engineers have figured out a solution to reduce indoor air pollutants.
