Covid-19 & Indoor Spaces

‘Covid-19 & Indoor Spaces’


Centers for Disease Control and Prevention (CDC) recommends a layered approach, using multiple mitigation strategies, to reduce exposures to SARS-CoV-2, the virus that causes COVID-19:
Improvements to building ventilation, to reduce the spread of disease and lower the risk of exposure

SARS-CoV-2 viral particles spread between people more readily indoors than outdoors. Indoors, the concentration of viral particles is often higher than outdoors. When indoors, ventilation mitigation strategies can help reduce viral particle concentration. The lower the concentration, the less likely viral particles can be inhaled into the lungs (potentially lowering the inhaled dose); contact eyes, nose, and mouth; or fall out of the air to accumulate on surfaces. Protective ventilation practices and interventions can reduce the airborne concentrations and reduce the overall viral dose to occupants.

Reoccupying a building during the COVID-19 pandemic should not, in most cases, require new building ventilation systems. However, ventilation system upgrades or improvements can increase the delivery of clean air and dilute potential contaminants.

Consult experienced heating, ventilation, and air conditioning (HVAC) professionals when considering changes to HVAC systems and equipment. Buildings that provided healthy, code-compliant indoor air quality prior to the pandemic can be improved for pandemic occupancy using less costly interventions.

Is Your Building Healthy For Breathing?

Do you meet the WHO minimum requirements? ‘Roadmap to improve and ensure good indoor ventilation in the context of COVID-19’ Executive Summary: The risk of getting COVID-19 is higher in crowded and inadequately ventilated spaces where infected people spend long periods of time together in close proximity.

Aerospace Giant Boeing Dismisses Ionisation Technology

Reference an article in the American ‘Kaiser Health News’ on ‘Do air purifiers protect against Covid? Lawsuit says company makes ‘false’ claims’. In summary the Aerospace giant, Boeing, completed its own studies and found that ionisation technology isn’t effective enough to use in planes. The Company’s study is being debated in a proposed class-action suit.
