BioShieldUV 72W HVAC UV Light Air Purifier Light Bulb - Air Filter UV Lamp for Air Conditioner Whole

Great product for the price! The template was accurate for me. I measured the wrong section of ductwork thinking i had plenty of room, but where I ended up putting it was less wide, and it was a squeaker! The ductwork was 16" and the unit was 15 3/4". In hindsight, I would have added a spacer on the outside of the ductwork under the panel to give it a bit more room, but the bulbs weren't touching the far side, and are working fine. I can add a spacer later on. It was near impossible to keep the cutouts from falling in - they are still sitting in there. Ha! This unit replaced a very expensive UV system that was installed incorrectly over the furnace filter. DO NOT install this anywhere near the filter - the UV will shred them, and ultimately plug up your furnace. Also - the old unit did not cover a lot of space in the ductwork. You want to make sure you put this in the longest stretch of ductwork (straight - no corners) that you possible can. The longer the exposure time the air passing through gets, the more efficiently the UV will kill everything. Mine is installed along 20 feet of straight ductwork. I was spending $50 a tube x2 yearly for the old system, plus $140 a year for filters, changing them every 3 months. This unit saves me a lot of money! Two 72W tubes every 6 months for $35.00 available through the company. I am super happy with this! It didn't cost a ton of money, was easy to install, and is cheaper to maintain. And yes, it really works. I'm living in a moldy house, and it keeps me and my dog from becoming ill. I run the whole house fan a lot, so the air is going past the UV quite a bit, and it really makes a difference! Read more

I bought this 18w unit back in 2023. Was an easy install inside the main air plenum where the incoming air hits the filters. The wiring was easy and they give lots of length to reach the HVAC switched plugs. Since installation, I have noticed a remarkable improvement with my asthma, especially in the fall and spring. This little add-on is so good that sometimes I forget that I installed it! I check on it regularly when I change the filters and today, I just noticed that both bulbs had burned out. Luckily, my purchase came with a spare set of bulbs so I replaced them and all is good. I now need to order another spare set in case of bulb failure. I have not noticed any odd scents or odors when the system is on. Breathing is way easier for sure! Read more

The install was easy. Seems to be working as air quality in my rental "feels" cleaner and my wife hasn't had smell issues so far Read more

very easy install. only drawback is that you have to piece gasket together. nice if it was fitted Read more

This works great for keeping mold out of the AC unit. We live in a humid area and this has done a good job in eliminating the mold that had frequently appeared in the unit. AC technician highly recommended this and he was right. Installation will require a power drill and some DIY skills as well as 115v power nearby. Hire someone if you are not comfortable cutting a 2" hole in the side of your AC unit. Read more

I accidentally ordered the wrong units, but the fantastic support team quickly guided me to the perfect lights—what a relief! The quality is top-notch, and the kit includes everything an average homeowner might not have on hand (like a drill and screwdriver). These kits are absolutely impressive, and if you're a DIY enthusiast, the installation is a breeze—super simple and satisfying. I added two 36-watt units to my HVAC system, and my wife, who's incredibly sensitive to allergies, immediately noticed a dramatic improvement in our air quality. It's made our home feel fresher and healthier! I spent ages deciding where to buy from amid all the options, but choosing this American company was a no-brainer. Knowing I'll easily get replacement bulbs in the future gives me total peace of mind. Highly recommend—these are game-changers Read more

It works, I hope this brand last. The other brand didn't last, the lamp ballast failed just after one year. And it was expensive to maintain. The BioShieldUV 75Watt has two bulbs and the cost for two bulbs is 2/3rds cheaper than the old brand with one bulb at 18watts. Read more

It's got a nice metal housing and everything looks solid. BUT when it stops working after 9 months and you look inside to see what failed in this $100 you spent, this little $.50 electrical component was garbage that burnt out. Read more
