Air Purifiers & Negative Pressure for Dental Offices

“The current pandemic has created a lot of concern about indoor air quality for my Orthodontic staff and patients. Working and caring for patients in a safe environment is of absolute importance as an Orthodontist. Setra's AIIR Watch has helped alleviate this concern in my office. The ability to sterilize indoor air is very reassuring to my office team and patients. Clinical dental assistants are able to work without fear and the front office team finds it comforting that a medical grade purifier is providing the safest indoor air at all times. Patients have themselves expressed their admiration for the product and the value proposition it offers. I find AIIR watch to be of significant value for my office.”

Setra AIIR Watch Advanced Air Cleaner & Negative Pressure Machine

The Setra AIIR Watch has been used widely in dentist offices to stop the spread of airborne infections, including COVID-19. AIIR Watch has a dual filter system that traps and kills airborne pollutants via HEPA and UV Light filtration. AIIR Watch then exhausts this scrubbed air outside through a window, into a HVAC return vent, or into space above a drop ceiling. When patient safety matters, dentists trust AIIR Watch.
