Clean air will make your business safer for your customers and staff

Businesses can make sustainable changes to their indoor spaces to reduce the amount of shared air that transmits respiratory viruses like SARS-CoV-2 to help us get through not only this pandemic, but also the next.

Clean Air Stars is maintained by Dr Pieter Peach, an anaesthesiologist who sees cleaner indoor air as one of the sustainable, minimally disruptive interventions that can be cost-effectively implemented to reduce the impact of future waves of SARS-CoV-2 to help reduce the need for future restrictions.

He started out his career as a microbiologist/virologist, and after medical school undertook postgraduate training in public health and epidemiology before training in anaesthesiology.

This project receives no benefits from any of the businesses, services providers, or goods manufacturers mentioned.

Outdoor interactions are the safest

Interacting with people outside reduces the risk of transmission by up to 20x

Improve mechanical ventilation

Where mechanical ventilation exists, ensuring it is adequate for the number of people for the type of activity is important

Improve natural ventilation

Simply opening windows and doors whenever possible can help dilute the amount of respiratory aerosols containing virus with fresh air. This is not always sufficient, and can be weather dependent. The adequacy of natural ventilation can be determined by using a carbon dioxide meter (CO2 Meter) and ensuring it reliably reads below 800ppm

Install portable air cleaners (HEPA filters)

Where ventilation is not reliably adequate, HEPA filters can help reduce the amount of aerosols containing virus in the air and help reduce the risk of transmission.
