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.

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.

I am a disabled agent orange Vietnam veteran this "pandemic" gave this consideration a priority due to my health. I have installed three (3) iWav-R in my Arizona home year-and-a-half ago (1) in my wife business and (2) in my home rooftop AC. I feel very safe to be home with iWav-R in my Arizona home. The level of airborne dust and in my home has noticeably reduced and other pollutants. As of this year I finally able to drive to my California home and installed (1) iWav-R in my California home AC due to this new strain Delta and Omicron strain emerged worry me about my families living in my California home. My priority to install this iWav-R keep my kids and grandchild safe in my California home.

My lungs really are glad I did this.

My lung doctor, told me to get this, product and I'm so happy that I did. I have had blood clots and one destroyed the top part of my left lung. I had trouble breathing, especially whenI was sleeping. Since it's been put in, my breathing issues have improved, so much better, I don't have the bad pain, trying to get air.
No more bad smells in the house, I've noticed that I haven't had to dust, and no more itching from the dog's hair. My grandson came to visit and said that the house smells fresher. I bought an old house that had a lot of water damage from large cracks in the foundation and leaked water. No more stagnant water smells in the basement. It's been in a week now and I just notice no more mold in the corner. My husband snores and would wake up with sinus drainage and so far the last two nights and mornings he hasn't had any issues. So I'm giving it an A+. I've been telling everyone about it. We need to have this put in the school's, for our children, to help stop the germs and viruses from spreading. . Worth the money!

Meets Expectations!

Had this installed about a month and a half ago. The level of airborne dust in my home has noticeably reduced. Recommended by my daughter, and so glad we followed her lead!

Wish We Had Gotten One Sooner!

My wife and I found out about the iWav-R from a physician friend during the initial Covid pandemic. We gave it some considerationt about having one installed, but thought "the pandemic will be over soon." Right. When the Delta strain emerged we didn't hesitate to purchase one and get it installed ASAP. The greatest "plus" is the peace of mind this unit provides for our health and the health of others who visit. Realistically you should allow two to three weeks before noticing any sort of a big difference in air quality. We have two large dogs and several other pets and we are now noticing the difference in air quality from the pets as well as cooking odors. Our only regret is not getting one sooner! Great vendor, excellent communication and fast shipping. The i-Wav-R is one of the single best home investments we have ever made. This is a no brainer.
