What Is PM2.5?
PM2.5 refers to tiny airborne particles 2.5 microns or smaller—small enough to bypass your lungs’ defenses and enter your bloodstream. While traffic and outdoor pollution are common sources, indoor PM2.5 is often overlooked.
Common indoor sources include:
- Drywall dust from renovations
- Smoke (cooking, candles, tobacco)
- Polluted outdoor air entering the home
The Health Risks
These fine particles can linger in indoor air for hours—especially after construction—and may cause:
- Coughing, throat irritation
- Shortness of breath or wheezing
- Fatigue and headaches
- Worsening of asthma or allergies
- Greater risk of illness and slower recovery
How to Protect Yourself
If you’re planning a renovation, make sure your contractor uses dust containment and HEPA-grade air filtration. For ongoing protection, consider installing a whole-home HEPA system—it’s more effective and cost-efficient than multiple portable units.
Cleaner air means better health. Don’t let hidden particles compromise your home environment.
