The Illuvia HuAIRS is designed to clean the
air in the "dirty donut," the area surround-
ing the sterile field, by filling it with clean
air. Every 5 minutes, the unit shoots out a
horizontal flow of air that has been run
through its HEPA filtration system and C-
uVC ultraviolet technology. The unit, which
can be wheeled to any desired spot within
the OR, has a display that allows users to
monitor air quality, particle mass, temper-
ature and humidity in real time on the unit.

the incidence of either incisional or prosthesis-related surgical infec-
tions. The CFU density at the incision site was "significantly" lower
when the Nimbic Systems' product was used.
Disinfecting the air
Another class of products aims to disinfect the air. One, called the
UV24 System, both filters and irradiates the air in your OR to kill or
trap bacteria, viruses and fungi. With just one air change, the device is
said to remove 97% of pathogens. The device fits behind your fluores-
cent lights and operates quietly. It's said to remove MRSA, VRE,
Acinetobacter, Streptococcus species, Influenza, VZV, Pseudomonas
and Clostridium difficile. Light baffles prevent the UV radiation from
reaching the room.
Another, the free-standing Illuvia system by Aerobiotix, is said to cut
air bacterial levels by more than 50% in occupied ORs. This system also
