Self-installed easily and noticed the air quality improvement within several hours. Also changed the system air filters at the same time. Located in return air, just after filter, before coil. It's been a month since installation and the filters are far dirtier than in the past, so something has clearly changed. Was highly recommended by my HVAC company. No maintenance needed, hoping for years of service. Considered UV lights but this seems a better solution.

I'm giving this unit high marks based on the reviews and recommendations of others online. I found it relatively easy to install myself. However, I wish there was a direct or indirect way to verify that it is doing what it is supposed to do. The only indicator besides the "on" LED is to monitor the air filter and see if it loads up faster.

Nu-Calgon iWave-R seems to be doing what I expected. This is my first experience with such an item. I read many reviews & decided to go for it. I have a gas furnace & central A/C & this air cleaner does seem to reduce dust on furniture. Being installed in Feb. didn't give much time to test with the furnace before spring arrived & switched to A/C. I don't have indoor air quality issues that some have said made a big difference.

Installed the I-wave in November and checked it today. It is working properly (24-7). I need to change the HVAC filter as it is collecting more dust as expected. The I-wave is one more step in fighting the pandemic covid19 and other bugs.
