Abstract
Breathing circuit Biters (BCFs) are used in respiratory and critical-c are settings for humidification of air and to limit transmission of re spiratory pathogens. Three types of BCFs (Pall BE 25A, BB 100, and HME 15-22) were evaluated (in triplicate) for removal of Mycobacterium sp ecies. Filters were challenged with aerosolized Mycobacterium bovis (a surrogate for Mycobacterium tuberculosis), at minimum total concentra tions of 10(4) colony-forming units. No hi bovis was recovered in the effluent, providing removal efficiencies of >99.99% to >99.999% for th e filters tested.
