Opening windows almost always reduces the risk of contamination with SARS-CoV-2. But it is important to be aware of low outdoor air temperatures that could affect the comfort of occupants and exacerbate related health problems. 

Although close contact transmission is the dominant transmission route, long-range airborne transmission through small size infected aerosols plays an important role in spreading COVID-19 in indoor spaces. Ventilation is air exchange between inside and outside; it dilutes the concentration of contaminants, and hence helps to control aerosol-based cross-infection risk of COVID-19.

AIVC Ventilation Information Paper #42: The Concept for Substituting Ventilation by Gas Phase Air Cleaning

AIVC's Ventilation Information Paper no 42: The Concept for Substituting Ventilation by Gas Phase Air Cleaning has just been released! The paper discusses and evaluates the pros and cons by partly substituting required ventilation by gas phase air cleaning.

VIP 42: The Concept for Substituting Ventilation by Gas Phase Air Cleaning

Worldwide, there is an increasing number of publications related to air cleaning and sales of gas phase air cleaning products. This puts a demand for verifying the influence of using air cleaning on indoor air quality, comfort, well-being and health. It is thus important to learn whether air cleaning can supplement ventilation with respect to improving air quality i.e. whether it can partly substitute the ventilation rates required by standards.

WHO Roadmap on good indoor ventilation in the context of COVID-19

The World Health Organization (WHO) developed and published a roadmap on how to improve ventilation in indoor spaces in the context of COVID-19. The roadmap is divided into three settings – health care, non-residential and residential spaces – and takes into account different ventilation systems (mechanical or natural). The roadmap is aimed at health care facility managers, building managers, as well as those members of the general public who are providing home care or home quarantine.
