As we are challenged by this pandemic with a high risk of being exposed to the virus, preventive measures can always be done and observed. Though some ambiguity is still present in the courses of transmission, it is still very important to follow CDC’s and WHO’s guidelines and recommendations in overcoming the outbreak. And as we follow one of its guidelines of staying home where the luxury of time is within our reach, we can do a house check of the things that can be further improved.
One vital example of a house check is inspecting the condition and set-up of heating, ventilation, and air conditioning (HVAC) systems which can all contribute to the potential airborne spread of the virus within the horizon of necessary precautions as a possibility arise from airflow generated by air-conditioning units which may facilitate the spread of droplets excreted by infected people longer distances within indoor spaces.
Proper ventilation systems provide clean air by exchanging indoor and outdoor air and filtering. Putting into consideration the modification and optimization of these systems can limit the viral spread and be part of the plan to protect you and your family.
Here are some ways to do it:
- Maximize the use of the HVAC system – HVAC systems may have a supporting role of lowering transmission in indoor areas by levering the rate of air change, accretion of outdoor air, and reducing the recirculation of air.
- Change the filter when necessary- Consider the first-rate type of filter that your system fan and filter can accustom for more satisfying function efficiency (seek professional HVAC contractors in Los Angeles)
- Use the system constantly as HVAC systems filtrate the air only when the fan is running.
- If your HVAC system has an energy-efficient air-to-air heat exchanger, a heat recovery ventilator (HRV) or energy-recovery ventilator (ERV) maximizes usage as they augment ventilation.
2. Airflow Pattern Options – Airflow management can be a vital role in lowering the spread of the virus.
- setting the speed to a slow and steady air
- vertical laminar is preferable
- positioning probable contaminated air out of rooms
- Increase Natural Ventilation – Poor ventilation in confined spaces corresponds to increased transmission of respiratory infections/viruses.
- Cross-ventilation is recommended. Opening windows or doors on opposite sides at home.
- Widely-open high and low windows at the same time from different floors.
- For added ventilation, multiple fans can be used; pushing air out of one window and moving direction.
