The ionization process reduces allergens, smoke and static electricity, and even controls odors and other particles in the air without creating ozone or any harmful byproducts. It works by creating positive and negative ions that attach themselves to these passing pollutants and gases until they get heavy enough to be trapped by the air filter. Learn More About the iWave-R Watch this video to learn more about the iWave-R iWave-R and COVID-19 The Center for Disease and Control (CDC) is responding to an outbreak of respiratory disease caused by a novel (new) coronavirus that was first detected in China. The disease it causes has been named “coronavirus disease 2019” (“COVID-19”). At this time COVID-19 virus has not been made available for testing. However, the iWave family of products have been proven through independent lab testing to significantly reduce a wide variety of pathogens and viruses similar to coronavirus in the breathing zone and on hard non-porous surfaces. It is important to note that we make no medical claims.
