Measuring Impact
Deep dive into what each AQI number really means for your daily life and planned activities.
Understanding the AQI Scale
Pollutant Encyclopedia
Knowledge is the first line of defense. Understand the sources and specific health risks of major pollutants.
PM2.5
Fine Particulate Matter
15 µg/m³ (24h mean)
Tiny particles (under 2.5 microns) that can enter deep into the lungs and even the bloodstream.
Sources
- Vehicle exhaust
- Industrial emissions
Health Risks
- Heart disease
- Lung cancer
PM10
Coarse Particulate Matter
45 µg/m³ (24h mean)
Particles between 2.5 and 10 microns, often visible as dust or haze.
Sources
- Road dust
- Agricultural burning
Health Risks
- Coughing
- Wheezing
NO2
Nitrogen Dioxide
25 µg/m³ (24h mean)
A brown, toxic gas that is a major component of urban smog.
Sources
- Combustion engines
- Power plants
Health Risks
- Bronchitis
- Increased sensitivity to allergens
SO2
Sulfur Dioxide
40 µg/m³ (24h mean)
A colorless gas with a pungent odor, produced mainly from fossil fuel combustion.
Sources
- Coal burning
- Oil refining
Health Risks
- Burning eyes
- Tightness in chest
O3
Ground-level Ozone
100 µg/m³ (8h mean)
Not emitted directly but created by chemical reactions between other pollutants.
Sources
- Chemical reactions between NOx and VOCs
- Sunlight
Health Risks
- Reduced lung function
- Permanent lung tissue damage
CO
Carbon Monoxide
4 mg/m³ (24h mean)
A colorless, odorless gas that blocks oxygen transport in the body.
Sources
- Incomplete combustion
- Traffic
Health Risks
- Dizziness
- Confusion
Smoke
Wood Smoke (PM2.5)
Satellite Detected
Specific particulate matter from biomass burning. AirSense uses NASA FIRMS satellite data to detect these plumes in real-time.
Sources
- Wildfires
- Crop burning
Health Risks
- Severe inflammation
- Systemic toxicity
The Mask Protection Guide
Recommended for AQI > 150No Mask
Best for: Clean Air
Effectiveness
0%
Surgical
Best for: Large Droplets
Effectiveness
20-40%
N95 Respirator
Best for: PM2.5 / Smog
Effectiveness
95%
N99 Respirator
Best for: Severe Pollution
Effectiveness
99%
Pro-Tip: To be effective, N95/N99 masks must have a tight seal around the nose and mouth. Facial hair or improper fit can significantly reduce protection.
Breathe Easy at Home
Indoor air can be 5x more polluted than outdoor air. Use these strategies to create a safe sanctuary.
Indoor Air Quality Strategy
Seal the Entry Points
Keep windows and doors closed when outdoor AQI levels exceed 100. Check for drafts around frames.
Use HEPA Air Purifiers
A High-Efficiency Particulate Air (HEPA) filter can remove 99.97% of PM2.5 particles from indoor air.
Natural Purifiers
Add plants like Peace Lilies, Spider Plants, and Aloe Vera which are known to absorb toxins like formaldehyde.
Control Humidity
Keep indoor humidity between 30-50% to prevent mold growth and reduce particulate suspension.
Avoid Combustion
Minimize the use of gas stoves, candles, and incense during high pollution days as they create indoor PM2.5.
Daily Cleaning
Use damp mops instead of dry brooms to capture dust rather than stirring it back into the air.
Smart Ventilation
Open windows only when outdoor AQI is at its daily minimum (usually mid-afternoon on sunny days).
Exhaust Fans
Always use exhaust fans in kitchens and bathrooms to vent pollutants directly outside.
