COVID-19 and HVAC Systems – What is the Relation Between them?

The spread of COVID-19 is showing signs of slowing down. Now, as the lockdown ends, businesses and workplace premises are reopening gradually. In such circumstances, when the spread s still multiplying but at a slower rate, it is necessary to take necessary precautions to protect employees and the office space from getting infected.

One of the primary safety precautions to take is with the HVAC systems. To ensure that there is proper natural ventilation in the building, HVAC systems are essential to maintain.

However, since the buildings and offices were closed for a long time, it is necessary to take care of the systems and give them a good clean.

HVAC Systems and COVID-19: How are they related

If you are considering reopening your building or office premise, getting routine maintenance done is critical. The systems have been shut down for a few weeks, and they might not work properly. After that, you must also get the recommended tests done to ensure that there is a proper flow of air and the risk of the virus spreading in its presence are negligible.

With the HVAC air purifier system, you will be guaranteed fresh air that would make your building safe for reopening. The air purifier will act as a filter between the air coming from HVAC and the premise. Why is the air purifier important?

COVID-19 spreads mainly from aerosol droplets due to coughing or sneezing. The average droplet size is 10 µm to 100 µm, which isn’t airborne and isn’t caught by the HVAC systems. However, anything below 10 µm can easily spread in the building as it stays airborne for almost 3 hours.

One of the best solutions is to install a filter for air purification. There are several filters like Merv-13 and others, which will remove nearly 90% of particles in the air and deliver fresh air. It is an important safety measure to adopt for stopping the spread of COVID-19 in the office premise.

Since the weather is changing, it is recommended to make use of natural light and air as much as possible. Central air conditioning transmits air from room to room, which is risky even if a single room has the possibility of getting infected. Opening the office windows to get fresh air will stop the spread of the virus as the powerful HVAC system won’t continuously push it.

If you work from home, you should let the outlet throw out all the indoor air to avoid the recirculation of COVID-19 particles. It will ensure that you are safe from the spread.

Safety should be your priority

It might look like a really small step to take for preventing the spread of the virus, but is an essential step nonetheless. HVAC systems with air purifiers can filter the particles outside and allow purified air to enter the premise. Safety should be your priority as you reopen your office. Along with proper sanitization, checking and maintaining your air conditioning is necessary to stop the virus from spreading.
