Air Purifier Whole House Uv Light in Duct for Hvac Ac (Air Conditioning) Duct Germicidal Filter + 2 replacement bulbs

I'm an electrical engineer with 20 years experience in HVAC control systems. I had purchased a very expensive Sterilaire unit years ago for our home air handler, and it was nothing but a huge headache, as it was too powerful and would scorch nearly any surface in its field of light. So, we kept having to relocate it. This nice unit is much easier to install, and works well with fiberboard ductwork which is so common in Florida. It took literally 15 minutes to install. I had the tools already, including a drywall hand saw, and HVAC foil tape. I recommend both, and in addition, I used longer black screws instead of the short ones supplied by the mfgr. I also copied the template onto a blank full sheet shipping label, which allowed me to peel and stick the template, to get it level. I installed mine in a vertical main return air duct, instead of on the supply side, so that any zapped pollen or virus particles kept captured by the 4"thick filters on our Carrier heat pump. One important tip: Never look at the bulbs unless you have welders glasses or the equivalent. UV bulbs can burn your retina. If you want to test the unit before you cut holes in the ductwork, place it in a closet or laundry room, close the door, and plug it in to an outlet outside that room or closet. You should see blue light coming under the door.. Unplug it before opening the door, and now you now it's a working unit, without risking damage to your retina. Lastly, I love that spare bulbs are included. The replacement bulbs for our Sterilaire unit cost $200 per pair, making it prohibitively expensive, whereas even at year 3, these bulbs can be bought for $30 a pair. Big difference. Now I need to find a smart plug to sync with my smart Tstat, so the bulbs are onky on when the air handler is running.

This replaced a unit that we had installed in '07. The old bulb was still working as recently as Easter this past Spring when I changed the furnace filter. I was surprised to find that typically the bulbs do not last that long. Also they are less effective as the bulbs age. So it was lit but probably not helping much. A couple months later I was in the basement and noticed the old light wasn't lit. I got this 2 bulb unit - with spares - for less than a replacement bulb for the old unit. PLUS everyone was out of stock for a replacement for the old one. But, so far, this seems to be a good unit. installation was pretty easy as I only had to make the existing hole a little larger and folded the small flap inward (out of the way) so I can put the old unit back in if ever needed and if able to find a bulb. If the bulbs last a year and if the included spares last a year - I'll be happy. I'd recommend this unit.

After Hurricane Katrina, we were advised to get one of these to eliminate mold in the air from items we retrieved in New Orleans. It’s a UV light like we see in doctors offices, mail salons etc. it kills germs. It’s installed on your Homes HVAC (AC) air intake box. The air sucked into the intake box is sanitized by the UV light as it passes thru the box and then recirculated in your house. We got this for covid. It’s an easy install for a handy man,about 15-20 min. Or your AC guy is probably familiar with it and can install it for you. The difference is his cost plus installation is about $300. You need to replace the build once a year. This one comes with 2 extras. It’s an extra level of protection.

Seems like a good deal! The company that services my heating & cooling wanted $650 to install a uv unit with only one bulb. I researched uv lights and chose to do it myself. Installation was helped by the seller when I emailed them a picture. They returned it with the place best to install circled. This was a big help as I have a whole house humidifier installed in the return air duct. Their choice of location was perfect, below the heat exch coil & solved my problem of whether to put it before or after the humidifier. Installation would have been easier if I had a metal hole cutter, but it's in and working and it comes with 2 extra bulbs. Also a long cord. A really easy thing to install for the diyer. Just be careful not to look at the lighted bulbs without uv eye protection glasses. I used ones that came with my automobile ac service kit. Update. I installed this in Oct 2017. Didn't replace bulbs after a year as recommended by manufacturer. My bad! What was I thinking? The bulbs were still ok after a year so I left them in and forgot about it. Lately I noticed a different smell to the inside air. Just happened to look inside theplenum where I had installed the UV lights. (I had provided an extra hole to look thru but kept it covered with tape). Both bulbs burned out! I'll replace them every year now. Live and learn. 🤭

The install was easy and the unit solved my problem of needing to go front to back instead of side to side as I could not get to the side of my duct work. I have a different bulb in another air handler that is longer and I like it but it doesn't fit. This has 2 bulbs which are shorter so I went from front to back. The template is off slightly but so minor you can adjust. Tips: 1. Be sure you have a plug nearby. The cord is long but I am still using it running out the door for now until I extend an outlet into the closet with my air handler. 2. Have AC tape ready. The screws are really worthless. you are screwing into fiberglass. If you screw in the metal, they might be useful. 3. The template shows an air handler from the side. Mine is below the duct work so I made sure the bulbs were side by side so the air passes through the middle of the 2 lights. I confirmed this with the seller who responded very promptly which gives me great confidence. The only drawback to this unit is what others have already pointed out. You cannot tell when the bulb is burned out. So I've put a reminder on my calendar to change the bulb in 12 months. My other UV light has significantly reduced odors in my house and fewer challenges with allergies for my son.

Great light for killing germs in the air as it passes thru my a/c system

Why does the producer or reseller tell exactly that its made only for the USA grid system and not to EU, UK power grid requirements? If they sell it here, it must be a 230V system and not a 120V system. And absolutely no technical warnings, or no labels for what voltage this system is made for. All that is seen is America flag, but that's it. Warnings are only for UV-C light. So I plugged into the EU power (In Slovenia) socket and it works for 2 seconds and thats it.
