In previous posts, we saw how HVAC filters help keep pollutants out of your home. But what about COVID? In today’s post, we take a closer look at this important question.
Can Your HVAC Filters Help You Contain COVID?
The COVID pandemic has changed the way we live and work. Limiting its impact is essential to regaining a sense of normalcy.
According to the Centers for Disease Control and Prevention (CDC), improving ventilation may help contain the virus in indoor spaces by preventing virus particles from accumulating in the air.
Good ventilation must be used in combination with other measures such as:
- Vaccination
- Wearing masks
- Staying six feet away from others
The CDC’s Interactive Ventilation Tool shows the percentage of airborne particles your HVAC system reduces when a guest visits your home. These are the figures:
- 52% reduction after a four-hour visit with closed windows and your HVAC operating constantly with MERV 6 filters. Using ventilation for an hour after the guests leaves increases the percentage to 72%
- 61% reduction after a four-hour visit with an open window and your HVAC operating constantly with MERV 6 filters. Using ventilation for an hour after the guests leaves increases the percentage to 82%
- 87% reduction after a four-hour visit with closed windows and your HVAC operating constantly with MERV 13 filters. Using ventilation for an hour after the guests leaves increases the percentage to 99%
- 88% reduction after a four-hour visit with an open window and your HVAC operating constantly with MERV filters. Using ventilation for an hour after the guests leaves increases the percentage to >99%
So yes, according to the CDC, using high-quality filters can help you reduce the number of virus particles in the air, especially when combined with other steps like opening a window during visits and using ventilation for an hour after guests leave.
