The data for the AS150MM Minimate (FAB) on
the
physical and bactericidal efficiencies of the ion emission
suggest that the reduction in the indoor aerosol concentration
combined with the germ inactivation can significantly reduce
human exposure to indoor air pollutants. This reduces the risk
of adverse health effects.
