Review on GPS Nu Calgon IWave R 4900 20 Generator by Christine Moore

Installed an iWave ionizer in the duct before the evaporator coil in our HVAC system. A differential pressure switch was used to turn on the ionizer when the A/C fan started and a separate 24 VAC power supply was used to start the ionizer. I started the ionizer with a fan in automatic mode for 72 hours and felt cleaner air while breathing. The sinuses opened up and I stopped breathing through my mouth at night. We're both sleeping better now. The house smells fresh too!
