- HVAC system is regularly maintained by an HVAC professional.
- HVAC system uses filters that have a Minimum Efficiency Reporting Value or “MERV” of 13 or higher (check with HVAC professional before upgrading filters).
- HVAC filters are surrounded by a good seal, so that no air by-passes them. Each room has a minimum of six total air changes per hour.
- Where you are not confident that your HVAC system provides six total air changes per hour, or where there is no HVAC system, each room has appropriately-sized portable air filters.
- HVAC system brings in some outdoor air and, at a minimum, meets ventilation standards.
- HVAC system provides ventilation and filtration at all times while building is in use.
- In higher-risk spaces, such as communal eating or sleeping areas, additional measures are used to achieve more than six total air changes an hour. For example, additional measures may include:
- If possible, HVAC system brings in 100 per cent outdoor air.
- Where room conditions such as ceiling height allow, a professional has installed upper-room ultraviolet disinfection.
- Bathrooms are equipped with appropriate-sized fans that exhaust to the outside.
- Room air is changed over at least three times between appointments or groups.
Here is the full checklist.
