ing that pathogens are destroyed.
• Vaporized hydrogen peroxide. Hydrogen peroxide vapor systems
deliver heat-generated vapor, which uses oxidative processes to kill
microorganisms through a high-velocity air stream, thereby achieving
even distribution throughout enclosed areas.
• Aerosolized hydrogen peroxide. AHP systems deliver hydrogen
peroxide via pressure-generated aerosol. The solution is usually about
5% to 6% hydrogen peroxide along with a very small percentage of sil-
ver. A unidirectional nozzle distributes the aerosolized droplets.
• Cluster ions. These use a germicidal mix of pure cluster ions,
which actively seek out pathogens via electromagnetic charge. On con-
tact, their stored energy is unleashed through the pores of cell walls,
destroying bacteria from the inside out.
• Ozone gas. These use electricity to turn oxygen into ozone, which
is a highly effective oxidant that kills all microorganisms. Ozone natu-
rally turns back to oxygen after reacting with pathogens and other pol-
lutants. A fan circulates the air in the room, bathing all exposed sur-
faces and helping to penetrate hard-to-reach areas.
• High-intensity narrow-spectrum (405 nm) light. Used in light fix-
tures, visible violet-blue light in the range of 405 nanometers targets
intracellular porphyrins, which absorb it and produce reactive oxygen
species. It's not as effective as UV-C light, but it can be used in areas
occupied by patients.
Customer support
Besides how well the system disinfects, factors like price, support and
service should help guide your buying decision.
Are maintenance contracts built into the price? Is the vendor going
to spend time in your facility and explain how best to use the equip-
ment in your environment? Will you have access to expert advice on
