What is indoor air quality?


Published: December 9, 2014

What is indoor air quality and why is it important to me?



Indoor Air Quality, or IAQ, is the condition of the air cleanliness, temperature, and humidity within and immediately surrounding a building. Carbon monoxide, radon, volatile organic compounds, microbes, and airborne dirt all have an effect on IAQ.

Indoor pollution is the most common cause of indoor air quality problems, and can come from a variety of sources. According to the EPA, these include combustion sources such as oil, gas, or kerosene; some building materials and furnishings; household cleaning products; personal care items; and those used for specific hobbies. There are also many outdoor sources of pollution that may enter the house. Outdoor air can enter through openings, joints, and cracks in walls, or by simply opening doors and windows.

It is important to ventilate your home, allowing outside air in and releasing indoor air pollutants and preventing them from building up. However, it is also important to filter the air inside your home, to help remove some of these pollutants as well. Poor indoor air quality can result in or exasperate a variety of health problems, as well as diminishing the comfort of your home. For maximum indoor comfort, it is important to regulate the temperature, humidity, and cleanliness of the air you breathe.

There are several options for your HVAC system to help regulate your indoor comfort and air quality. Mechanical and electronic air filters effectively clean indoor air. Humidifiers restore proper humidity in the winter, while air conditioners de-humidify the air in the summer. Ventilation allows air to be exchanged with outside air, so the indoor air does not become stagnant.
