IEQ InSight Restaurant Air Quality Explorer

Measured during real restaurant visits

Restaurant Air Quality Explorer

You can see the dining room. What do you know about the air?

Explore dining-period CO₂ and fine-particle measurements, one restaurant visit at a time. Results describe the monitored space and observation period.

How to read these measurements

Each row is one monitored restaurant visit. The quadrant uses mean CO₂ and mean PM₂.₅ during that visit, not the peak particle value. These are IEQ InSight comparison categories using selected reference lines of 900 ppm CO₂ and 15 µg/m³ PM₂.₅, not official AQI categories or health certifications. A visit mean does not describe every moment or every area of a restaurant.

The 15 µg/m³ particle line is used as a comparison reference; a dining-period mean is not a 24-hour average. Cooking activities, occupancy, outdoor conditions, instrument, and visit duration can affect comparisons.

The initial two entries cover American dining at the Cheesecake Factory in Sunrise, Florida, using a TSI Q-Trak XP with a one-minute sampling interval. Monitoring times are shown as supplied in the visit record. Peak PM₂.₅ values are reported from the summary file; the peak averaging definition has not been specified.

Detailed findings, charts, and academic work are available on Research & Publications.
