The copper evap coils were less likely to have mold, virus and bacteria problems. Notice very old buildings have copper doorknobs because virus and bacteria are less likely to be spread with copper.
I've seen videos of UV lights being installed in the return no where near evap coil which defeats the whe purpose of preventing mold etc from growing on evap coil. Takes extremely powerful UV to kill stuff in moving air alone.
Mold spores are large enough to be captured by certain MERV-rated filters. Although smaller, the same is true for bacteria and viruses. They are all "particles" just like dirt, dust, pollen, etc. This is why since the start of the pandemic, ASHRAE has recommended MERV 13 filters in commercial environments where possible. Whether you can use a filter like this in a residence depends on how it is designed to work with the heating and cooling equipment (size of the filter, pressures on the system, etc.). UV lights (also recommended by ASHRAE) are great to ensure you will have a clean coil surface but they would certainly not be my primary solution.
but hold on a minute... NO one ever talks about Ozone! Isn't Ozone a byproduct of UV-C rays, and isn't that also EXTREMELY toxic and harmful to living things, including humans? How then, does it make any sense to put these lights inside a ventilation unit that would distribute Ozone throughout all of the vents and into every area of your house??? Please, can someone tell me that I'm wrong about this?
It depends on the wavelength of UV light. Some wavelengths can create Ozone and others do not. Ozone (O3) is created by UV when wavelengths in the 160-240nm range react with oxygen and cause individual oxygen atoms to bond and create O3, or Ozone. UV-C is a longer wavelength of UV light that does not do this.
All i know is i installed one on my furnace in the house i lived him for about 8 years. I live in North Dakota, I got a cold maybe 2-3 times in years. I have 30 years in the hvac trade. Just purchased another Sanuvox for new home. I also installed Trion Air Bear merv 11 and charcoal filter. UV is used in reverse osmosis process for water, UV lights now available for ice machines, work awesome. Nucalgon Wave 1 has no uv bulbs to change every 2 years or so. $150 for replacement sanuvox uv bulb, Wave 1 is supposed to be self cleaning and needs to be mounted between the air filter and before the a- coil on a up flow furance. Wave 1 mounting location options are limited. Usually hidden away in blower compartment but can mount on exterior if metal ducf limitations
What's the aftermath? And no, I don't own one...also, I believe this video is about a coil light is it not? I don't hear anything mentioned above about an air scrubber, unless you are just using the general term..
Does the uv breakdown the plastic parts of the A coil? My A coil has plastic drip trays. Also does this help reduce allergins in the air? My son has mild seasonal allergies and seems to always be clearing his throat. I was thinking of adding a UV unit to our hvac unit to help with this. Also we run our hvac blower all of the time to keep air moving around the house.
Seems nicely made

UV light is not fillteration at all . The air filter is the best thing you need to buy the uv light just kills all stuff that the air filer didnt get

@neal cassady yikes! You must not know how these things work 😬 that's even cuter 😍

Would you recommend to use two uv lights.one in the center inside the coils,and one on top of coils? Thank you.
And you left out MERV ratings for filter media why?
