How can I create a negative pressure room in my clinic?

Adding negative pressure airflow to an isolation area for COVID-19 patients provides additional protection against the spread of infectious droplets.

Negative pressure systems use ventilation (like fans) to move air into an isolation area and positive pressure systems move air out of it. You can add a negative pressure system to an isolation area and a positive pressure system to the area just outside of it to quickly to increase infection prevention and control. For a negative pressure system to work, the air leaving the room has to be enough to make sure air outside the room is pulled into it—if air leaks out under doors, infectious particles could escape.

Many ideas about setting up negative pressure systems have appeared online of various degrees of reliability, usefulness, and practicality. Our team is looking at those online resources and has found a few that we feel are the most reliable and practical. Other online resources we found are also listed below.


Follow procedures carefully to make sure air from isolation rooms is properly vented. Room should have a dedicated bathroom. Limit patient transport and patient transfers. AIIRs should be reserved for patients who will be undergoing aerosol-generating procedures. ASHE suggests consideration of the following methods for creating negative rooms: HEPA to corridor HEPA to outside HEPA to return Multi-bed zone-within-zone room
