Ionization produces a high concentration of positive and negative ions, delivering them to the space via the ventilation system. Within the air stream, ions attach to particles, where they combine, become larger and are more easily filtered from the air. When ions come in contact with pathogens, they disrupt the pathogens’ surface proteins, rendering them inactive. The Ionization process kills mold, bacteria and viruses in the evaporator coil and throughout the breathing space. It also reduces allergens, smoke, odors, static electricity and dust particles.
Many ionizers treat the air quality in classrooms at schools and universities without creating ozone or other harmful byproducts. Confirming the ionization product has been tested and meets the UL 867 standard for no ozone admission is the best way to verify this. Clean outdoor air near waterfalls, on mountains and near ocean fronts contains around 5,000 ions per cubic centimeter. Engineered ionization devices replicate the ion levels in the cleanest environments by increasing the indoor levels of ionization, providing the ions necessary to kill pathogens, control odors and reduce particles.
Ionization often requires no maintenance or replacement parts. Some models are self-cleaning and feature universal voltage for easier installation. Ionization should be part of a comprehensive indoor air quality program to make sure the breathing zone in schools is cleaner and healthier for students.
