Our air quality has never been as vital as it is now. The most recent pandemic has shown us that our health is essential and good air quality plays a crucial role in keeping our families and children healthy.
Scientists and researchers are continually gathering new evidence about COVID-19, including routes of transmission.
COVID-19 is commonly spread from an infected person through prolonged close contact (defined as being within 2 metres for 15 minutes or more). In addition, having physical contact, such as hugging someone, touching something with the virus on it, then touching your mouth, nose or eyes before washing your hands, can contribute to the spread. Also, respiratory droplets are shared when you cough or sneeze; and aerosols, which are tiny droplets, can stay in the air for longer.
One way to care for the air quality of your home is to seek out professionals like Golden Line Green Care to make sure your home’s air ducts and other utilities are clean and in working condition.
Data suggests that COVID-19 can more easily spread through the air when there are a higher number of people indoors, for a more extended period, with poor airflow or ventilation. Factors contributing to the transmission may include activities that cause heavy breathing, such as singing, dancing or exercise, especially without precautions such as wearing a mask or keeping a physical distance.
If they are not cleaned periodically, dirty ducts can potentially recirculate germs and infections. Whichever way you look at it, that isn’t good for indoor air quality. Regarding Covid-19, the public perception has been that the virus is transmitted only through direct contact, such as through droplets and surface contact.
Our health is the number one priority, and good air quality plays a crucial role in keeping our families and children healthy. Homeowners should always be keeping an eye on their air quality in their homes.
Heating, Ventilation, and Air Conditioning (HVAC) System
HVACs and their filters are designed to reduce airborne pollutants, including virus particles, when they circulate through the system. HVAC filtration can reduce the risk of transmission indoors when used with other public health measures such as physical distancing and wearing masks. It is important to ensure regular maintenance of the HVAC systems in your home, business, workplace or school. Ensure HVAC systems are in good working condition. Increase air-exchange settings on the HVAC system, if possible. Use the highest efficiency filters that are compatible with the HVAC system(s). Keep areas near HVAC inlets and outlets clear. Arrange furniture away from air vents and high airflow areas. Avoid re-circulating air.
Public Health Measures
While ventilation and air duct cleaning is important, it must be used along with other public health measures. There is not one public health measure that can guarantee protection from COVID-19; multiple strategies are needed. Other measures include symptom screening and self-isolation for people with symptoms, practicing physical distancing, wearing a mask at all times when indoors*, and practicing good hand hygiene and respiratory etiquette. Engineering control measures, such as physical barriers, can also be used, however be sure they do not negatively impact airflow and ventilation within the space.
