## Description

This is a genuine replacement part. The model number and name for the following item is: Nu-Calgon 4900-20 i-Wave.

Review: Easy clean air. It’s like magic, but real. (Not kidding) - Very simple installation, but I am a licensed mechanical journeyman. Universal voltage between 24-230v and 2 watts consumption makes placement a breeze. The device size is tolerable, and mounting in the air handler is a simple task with the integral neodymium magnets. However placement in other areas will be simple too with the included hardware. The green LED indicator is lit when active, and the device makes an audible squealing noise that you can hear if you are within 12 inches of the device. The device is zero maintenance due to the automatic cleaning preprogrammed every 3 days. My personal observations over three days of use are: 1. The conditioned spaces have no odors. 2. Throw out the scented candles, because the scent will not last more than 60 minutes if the circulator fan is active. 3. The research on benefits bipolar ionization is solid and professional. Just search NPBI and look at controlled independent results posted by Global Plasma Solutions and it’s partner Aviation Clean Air.
Review: Easy install - Effective results - Allergy Relief - Odor Elimination - 4 Dog house - Installed this last night and have started following the manufacturers recommendation and I am letting the system run continuously for the first 72 hours. To do this I just set the fan to ON and the thermostat at my desired temperature so the AC will kick in when needed. This unit is wired to the power lead for the blower motor as it works with any AC current between 24 and 240 volts. My AC system is horrible...the return basically intakes air from the floor...so the entire system is constantly filled with dust and dog hair due to owning 4 very large dogs...add to this the general odor from these four beasts...and you have to constantly clean and deodorize...and then it all smells like wet dog... Been researching an approach to sanitize the air and generally improve air quality in the home...I am a fan of UV sterilizers but felt I needed something more effective and maintenance free... I stumbled upon this product and did some research...was skeptical of this new technology... After installing last night within 15 minutes we could notice a difference as the air seemed fresher... Slept better...and allergies seem to be improving... Dog stench seems to have dissipated The real test will come when we steam clean the carpets... Will update in a few weeks...

### ⭐⭐⭐⭐⭐ This Does Work!
*by S***S on May 11, 2020*

Over the years I have tried a couple of different air purifying UV lamps with very little noticeable effect. I threw caution to the wind and purchased this silly looking 'air purifier'. To optimize performance, I run the blower motor on my furnace 24/7/365. If you are not moving air you are not purifying air. Does this device work? It actually does work...very well...noticeably well. My wife's post nasal drip is actually better. She does not complain of the 'gunk' in her throat or the crusty eyes in the AM. When I cook burgers or steaks (hot cast iron pan with lots of sizzle and smoke) the smell does not linger into the next day. Our large dog got sick in the basement one night (in a room with an air return). I did not smell it in the AM when I got up. I am super happy with this product. I cannot comment on mold or virus removal as it is not easily measured....but based on the other validated claims... it might just help with this, too. You will want to run your furnace fan more frequently if not 24/7 in order to maximize performance. If your furnace does not have an ECM blower motor (Azure from MARS) you might want to look into that.
