Some thoughts and numbers on ventilation during COVID

Virus is airborne; ventilation is key.
Purifier airflow rates of 3 litres of air per second per person are needed.
- This comes to 10.8 cubic metres per hour per person.
- Samsung AX7500K Air Purifier $999 is rated as CADR 701m³/hr (Clean Air Delivery Rate)
A fallback ventilated system (for a naturally ventilated building) comes into operation when the detected levels of CO2 in the air rise above about 800 parts per million, so it could reliably improve air quality.
