Does iWave produce ozone?

As the air flows past the Nu-Calgon iWave-Rpositive and negative ions actively purify the supply air, killing mold, bacteria and viruses in the coil and living space. The ionization process also reduces allergens, smoke and static electricity. In addition, it controls odors (cooking, pet, VOCs) and other particles (no more sunbeams) in the air without creating ozone or any harmful byproducts. This is one reason why consumers consider iWave vs UV light (broad-spectrum) as a good choice.

Working as advertised

This device is performing as advertised and seems to be helping with everyone's allergies. Everyone agrees that cooking orders are also quickly dissipated . Love that the item is self cleaning and maintenance free.

Allan Brake

The big takeaway is that it is maintenance free. No changing bulbs or other costly maintenance over time. I just got my I wave and looking forward to it providing cleaner air in my home.

Fantastic Device

The iWave -R has done the job that my other air purifiers failed to do ,at a noticeable difference.Sorry it took me so long to find out about it.My stuffy nose has cleared.Grandsons laundry soap order has disappeared

Easy install

Ordered the Nu Wave after much research and installed for about a week now. Used pro install to get warranty (!) but he was very pleased with the ease of installation.
I do not think that enough time has passed to really rate how well the air has changed yet but it does seem to have worked. I will update as it becomes more apparent and pollen season really kicks in around here.
