How iWave Ionization Differs From PCO Technology
Unlike iWave’s bi-polar ionization method, Photo Catalytic Oxidation (PCO) technology uses UV light, commonly with titanium dioxide (TiO2) and often with other alloys, to create ionization.
The Centers for Disease Control (CDC) has warned of cancerous risks involved with TiO2* – not something you want in a building’s air quality! ASHRAE issued a position document in January 2015 on Filtration and Air Cleaning where they cautioned UV lamps used in many PCO devices can emit significant ozone – known to be harmful for human health. They also observed and reported on page 9 of the document “…potential of an incomplete oxidizing process, which produces by-products of reaction that can be more toxic or harmful than the original constituents (i.e. formaldehyde). The catalysts can be contaminated (poisoned) by airborne reagents and/or products of oxidation, which results in reduced or total efficiency failure of the process.”
Lastly, the PCO approach requires the replacement of the UV cell every year or two. Bi-polar ionization requires no replacement parts, and on the self-cleaning models, they are maintenance free. The chart below shows several advantages of iWave technology over two common market approaches.
Frequently Asked Questions
WHAT MAKES IWAVE PRODUCTS UNIQUE?
iWave products are patented ion-generating devices that produce the highest available ion outputs and do not create ozone or harmful byproducts, which are different than current ionizers on the market. Not only that, these are self-cleaning options that require no maintenance, no replacement parts, universal voltage and universal mounting, making these highly versatile devices game-changers in the IAQ market for proactive whole home/office purification. The devices offer a superior three-year warranty – other products require light/cell replacement in a year or two.
WHAT DOES IT MEAN WHEN YOU ARE SAYING ‘KILLING PATHOGENS IN SPACE’?
The ions are circulated downstream of the iWave-F, iWave-V, iWave-C and iWave-R to where they thoroughly address pathogens through the coil, duct and living space, making it an active whole purification system. This is different than UV lights with a passive approach that only address pathogens that circulate past the UV light in the duct and only affect part of the coil.
HOW LONG WILL IWAVE PRODUCTS LAST?
iWave products are designed to last for a very long time, up to the design life of the air conditioning equipment.
