Open windows and doors, point the fan at windows: tips for avoiding the airborne spread of Covid-19 at home – Mothership.SG

With acceptance by thWorld Health Organization (WHO) As the SARS-CoV-2 virus can spread through the air, more attention is being paid to indoor air ventilation to reduce the transmission of the virus.

Singapore authorities – the Building and Construction Authority, the National Environment Agency and the Ministry of Health – recently issued guidance on ventilating confined spaces to prevent the spread of SARS-CoV-2.

The interior spaces specified in the guidelines are air-conditioned premises (such as shopping centers and offices) as well as naturally ventilated spaces (such as cafes, dormitories and markets).

For example, the guideline recommends purging air daily in air-conditioned spaces with mechanical ventilation (such as shopping malls and office buildings) and installing window-mounted exhaust fans in air-conditioned spaces without mechanical ventilation. (like retail stores).

However, some of the recommendations for natural ventilation in indoor spaces can be applied to homes.

You can improve ventilation in the home by opening windows and doors, especially when hosting guests who are not part of the home.

To improve cross ventilation, position a fan to blow out of the window. This will increase air exchange and disperse virus particles away from your home.

Point fans a way people because they could blow contaminated air towards them.

If you have an exhaust fan in the kitchen or toilet, you can run it at full capacity to expel indoor air.

Check other systems to make sure there are no unwanted air leaks in occupied spaces, including water seals in the sanitary system and cracks in pipes and ducts.

If you regularly turn on your air conditioning at home, it is better to turn it off because the the virus thrives in cool, dry conditions.
