IAQ Management Method

What is Indoor Air Quality (IAQ)?

IAQ (Indoor Air Quality) refers to quality of indoor air.
Main living space of modern men is indoors, so indoor air quality has become very important.

Modern men spend most of their days indoors, such as home, school, work, and public transportation.
This is why indoor air quality is important to health maintenance and management of modern men.
Natural ventilation is the best way to manage indoor air quality, however the reality is that we cannot leave windows wide open and ventilate due to fine dust and yellow dust.
Then, is it better to keep windows closed and not ventilate because of outdoor pollutants?

  • Increase of indoor life

  • Increase of cars and traffic

  • Increase of fine dust and yellow dust
