Welcome to our 🧵on clean indoor air! Each Monday we’ll post threads about indoor air quality (IAQ) and its significance to health. We’ll cover the composition of air, how to measure harmful elements, and how to improve unhealthy indoor air. 1/6

We can’t see or touch the air around us. However, it’s key to the planet and to life. It surrounds the earth and provides a protective, insulating cushion. It contains gasses vital to life: oxygen, carbon dioxide, water vapor and nitrogen. 2/6
Did you know our atmosphere is composed of 78% nitrogen and only 21% oxygen? These gasses support plants, animals and the nitrogen cycle, which keeps all life on earth in balance. 3/6
Outside air—or ambient air—makes its way into indoor air and carries with it pollutants, bioaerosols and particulate matter. Surprisingly, indoor pollutants can be 2 to 5 times higher than outdoor levels. Or even 100 times higher. 5/6
This is why healthy, clean indoor air is so important.
Join us next week to learn how we measure and evaluate Indoor Air Quality (IAQ). 6/6
Air also contains bioaerosols, floating microorganisms that stay aloft in the atmosphere. And it contains harmful chemicals from industrial contaminants and natural disasters such as wildfires. In high concentrations, these pollutants are unsafe. 4/6
