Air Purifiers for Dental and Medical Offices

Dental and medical offices generate aerosols constantly -- from drilling, suction, high-speed handpieces, and close patient contact -- which makes air changes per hour (ACH) one of the most important numbers in the room. We've selected units across a range of budgets so you can hit the ACH target that fits your practice.

General guidance calls for 8-12 ACH depending on the procedures performed in a space. Some regulatory bodies go further, tying specific ACH rates to how many minutes it takes to clear 99.9% of aerosols from the air. (continue reading)

Some regulatory bodies have gone further in defining these targets. The Royal College of Dental Surgeons of Ontario, for example, ties specific air changes per hour to how quickly a room clears 99.9% of aerosols -- higher ACH means shorter downtime between patients.

Air Management and Infection Control in the Dental Office, a resource from Henry Schein Dental, covers the range of filtration types available -- HEPA, ionization, UV, and more -- and notes a minimum of 8 ACH for efficient ventilation in medical office settings.
