Abstract
A mist generator improves the sterility of blowers having controlled forced air systems. In one embodiment, the mist generator has a chamber adapted to receive a disinfectant adapted for attachment to an output opening of a blower for delivery into the chamber of forced air carrying misted disinfectant. The main body also includes an output duct or aperture adapted for attachment to a second hose which, in turn, is adapted for attachment to an inlet opening of the blower for delivery of disinfectant misted air through internal components of the blower. Alternatively, there is used a disinfectant filter formed as a sterilizing grid having a screen coated with a soft porous surface material impregnated with a liquid disinfectant. The soft porous surface material releases said liquid disinfectant when forced air moves through the filter. In both embodiments, sterile water is introduced to take up residual disinfectant and the vapor captured in a dry filter or desiccant material and removed from the system. The mist generator improves the sterility of the blower to mitigate microbial contamination of forced air delivery systems.
