Clean and pure Indoor air is vital for a healthy living. A minor increase in indoor air pollutants may affect the Indoor Air Quality (IAQ) and give rise to immediate or long-term health problems.

As per EPA – “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. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns.”
