Highly surprised and super thankful I took the chance. Great quality and awesome packing job.
Well, this all started about 3 weeks ago when all of a sudden my wife started getting sick. And then she started to lose her balance. We were thinking that she had a inner ear infection. Well a few days later I went to get a drink from the sink and smelled mold. I'm like what the??? We have been at this property (well water) for over 5 years, and it's always been the very best water in the entire area (admitted by my neighbors). So when I realized we had mold in our well I was shocked. We had just replaced all the plumbing including the pressure switch and pressure tank. So everything was new. So I immediately got on Amazon and started looking for a UV sterilizer. There are a lot to choose from here and most are in the $250-$400 range. I was not ready to pay this much for a UV unit and found this one with no reviews. I was very leery and put it in my list and kept looking. But after almost 4 hours of looking and reading reviews I kept coming back to this one. I finally took the chance and ordered it. I am glad I took the chance. It took two days to get it (Thanks to Prime). I was pretty apprehensive about this, as I knew that there was going to be glass involved and was even more nervous when I opened the first box to find the second one from China. My heart sank and I really thought I had just got taken. But I steadied myself and opened the next box. And this is when every bad thought that ran through my head took a flying leap. I cannot begin to tell you how well this item was packaged. I really wish I had taken the time to take some pictures but since I did not I will describe it to you. Everything is wrapped and double wrapped in heavy duty air bags and bubble wrap. The main case of the light is polished Stainless Steel and is very large ( almost 3 feet). It comes with two bulbs and one quartz protection tube. All three were wrapped with bubble wrap and then inside was three hard cardboard tubes that were also bubble wrapped inside to protect the glass. This level of protection would pretty much save this box from most of the damage it could receive during shipping. The instructions are pretty easy to understand but you need to be extra careful when putting the two gaskets on each end of the quartz tube when inserting it in the main body. Don't let them roll and twist, make sure they are flat against the metal so as to get a good seal. At first I was worried about clearances as the quartz tube gets sealed in the unit on both ends with screw on caps, but it was for not. Everything went together perfectly. Once the quartz tube is sealed up there is a hole on one end that the UV bulb slides into. Then you just hook up the ballast wire connection and slide the cap over it. I used a black zip tie to help keep out the moisture. I then hooked it up to a 3 stage filter system and let it rip. We also sterilized our well with a gallon of bleach and we let the whole thing run for two days before hooking up the filter system. Then after the filter UV system was hooked up we ran it for another full 24 hours before drinking. It was worth every penny. It has been a week now and my wife is feeling much better and the water no longer smells like mold. In fact it has no taste at all. It's clean and great to drink. We even run our swamp cooler through the UV part just to keep the evaporated water from being able to expel anything. This is a high quality UV light Sterilizer and worth every penny I paid for it. Not all come with a extra bulb and none of them come at this price with a extra bulb. The ballast unit has two lights on it, one green and the other red. These indicate the condition of the ballast and the bulb. They both stay on when everything is working right. It's nice to see at a glance that the unit is working as it should. At night you can see the UV light glow through our water hose : ) So buy with peace of mind. I did not get this item at any discount or for free. I purchased this with my own money and took a chance. Now you can buy without those issues and perhaps this seller can make a living selling a good quality product.

Great company
HQUA has a great product that I use in multiple properties. The product is very easy to install and works as advertised. They are easy to get a hold of for Support and when I had a ballast have some issues after several years they immediately sent me a new one -far beyond any warranty period. I will continue to buy and use their product.

What a great product and fantastic support too
What a great product and fantastic support too. While installing the glass sleeve for the bulb to go in the sleeve broke at the open end so I reached out to the manufacturer and they were very helpful, told them what happened and they sent me out a new sleeve the next day. I would definitely buy from them again

Garbage
Customer service is unhelpful and won't respond after showing proof of defects that caused the quartz tube to break upon inserting the bulb. Wouldnt recommend as this productis almost 300 USD. Update 09-05-25- company sent 2 new quartz sleeves as replacement for the one that had broken as a good faith gesture. Shipping was quick and they came very secure. Install went with no issue. Havent tested the water but its not leaking and the ballast has a green light. Will update with any issues but I would give them a chance again.

Getting better water now
We have a well and wanted to ensure that the water was clean. We added a SimPure whole house filter with PurePlus Coconut shell activated Carbon filter with this HQUA-OWS-121 120V 40W 12GPM 1” Inlet/Outlet MNPT Whole House Ultraviolet Water Purifier system. We used 24" 1" flex metal connectors to connect them and for the output since they recommend at least 10" of metal pipe connecting the UV system because the UV and heat will degrade the PVC over time. There is a small hole on the cap on the end that is opposite the electrical connection that shows the bulb is on which is helpful. We did not have any problems with leaks on the unit once it was assembled. It appears to function as described and the water does taste better with these two items on it.

No leaks and seems to be running!
The directions were fine. Make sure you have enough clearance above to slip in the quarts cover and the Uv lights. Teflon and pipe dope your entry exit points. No leaks.

UPDATE: Ballast failure within six months of installation
After writing the review below and contacting HQUA they were extremely helpful and sent me a new ballast which I received a day later. The new ballast was definitely and upgrade and manufactured with a lot more attention to the environment where the filters and the equipment are located. Iv'e had it installed for a month and so far so good! Excellent company and great customer service. This uv filter is a simple install and relatively easy hook up to our whole home water filter system. Once we had it hooked up it was a relief to be able to drink out of our faucets again and even, with the help of the filtration system, hook up our ice maker. Have checked on the filters once a month and today heard an alarm in filter closet where the UV light is hooked up. Looked to see what the problem was and the cord to the outlet was disintegrated. The other electronic device (softener) was fine and I could see no signs of power surge or faulty circuitry from the outlet. After investigating a little I found that this was not an uncommon occurrence with this particular filter. I would have give this company five stars for their customer service and the quick response time but, in this case, and unless they have made significant changes to the ballast--steer clear of this one.

Great
Helped my newly dug well pass the bacteria test, it definitely works. Ours failed 3 times before we installed this filter. Great price too
