Why Indoor Air Quality Is a 21st-Century Health Issue

We spend nearly 90% of our time indoors, yet indoor air is often more polluted than outdoor air. Modern homes are built tighter for efficiency, which means contaminants have fewer ways to escape.

Common indoor air quality issues include:

• Dust, pollen, and pet dander

• Mold and excess humidity

• VOCs from furniture, cleaning products, and building materials

• Poor ventilation

Poor indoor air quality can contribute to allergies, asthma, headaches, fatigue, and long-term respiratory problems—especially for children and seniors.

Solutions aren’t one-size-fits-all. Proper filtration, humidity control, ventilation upgrades, and regular HVAC maintenance all play a role. Improving air quality isn’t a luxury—it’s a modern health necessity.
