Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the area. High temperature and humidity levels can also increase concentrations of some pollutants.

Filters and maintaining adequate ventilation along with source control are the strategies of controlling indoor air quality.

The HVAC filters used in your home’s heating and cooling system have an important job to do. They filter dust, pollen, pet dander, and other small particles out of the air that you and your family breathe. These particles are trapped in the filter to prevent them from being recirculated throughout your home. The higher the MERV rating, the more effective the filter will be.

Filters also play an important part in keeping your system free from larger particles that could damage it. Therefore, you want to make sure that you are always using the right type of filter and change it when it is dirty. Here are the different types of filters available for residential HVAC systems.

Cleanrooms are designed to maintain extremely low levels of particulates, such as dust, airborne organisms, or vaporised particles

After learning these concepts students would be more employable in HVAC Industry or self employed to cater to the needs of indoor air quality
