How It Works
The ION Defend uses patented NPBI technology to safely introduce new ions into your indoor airstream using the airflow in your existing ventilation system. When ION Defend is used in commercial and industrial buildings, ion levels have been measured to rival those of the highest concentrations of outdoor settings.

Annual Service Visits
Each ION Defend receives a complimentary annual maintenance visit for the life of your contract. Each visit includes:

  • Inspection of ion emitters
  • System calibration check
  • Verification that ions are produced according to spec

No Maintenance Required
ION Defend systems are self-cleaning and require zero regular maintenance.
