Limitations and Honest Assessment

PM2.5 Sensor Fluctuations

Issue (from independent reviews): PM2.5 readings "jump around between measurements"

What this means: Readings may show 15 μg/m³, then 25 μg/m³, then 18 μg/m³ in consecutive readings

Why it happens: Laser particle counting has inherent variability with low particle counts

Practical impact:

• Trend analysis still valid (hourly/daily patterns clear)
• Exact instantaneous reading less reliable
• Compare hourly/daily averages, not individual readings

Recommendation: Use for trend monitoring (is air quality getting better/worse?) rather than precise measurement

CO2 Reads High

Issue (from independent testing): Consistent 10-100 ppm offset vs reference sensors

Example: True CO2 = 800 ppm → View Plus shows 850-900 ppm

Why it matters:

• 800 ppm = Good ventilation
• 900 ppm = Adequate but could improve

Workaround: Mentally subtract ~50 ppm, or focus on relative changes (ventilation effectiveness) rather than absolute values

Airthings response: Within spec (±50 ppm ±5% accuracy), though at high end of tolerance
