- Deployed indoor air cleaners in homes/classroom where people who COVID positive.
- In home cleaners placed in isolation room, outside and in the main living area. After 1-2 weeks dust was removed from filters => extracted => qPCR analysis.

- Cool mist humidifiers were often used in homes/isolation rooms which greater decrease the flow rates of the air cleaners.
- Isolation rooms in homes had higher copy numbers.
- SARS-COV2 was detected in 2/7 deployed filters in classrooms/lunchrooms.

- CO2 concentrations roughly correlated with PAC1 biomarker for COVID19 in classrooms. (Cool!)
- Dust maybe a good tool to monitor for other viruses in the future.
