HQUA-OWS-12 120V 40W 3/4" MNPT Inlet/Outlet Whole House Ultraviolet Water Purifier Filter, + 1 Extra UV Bulb

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.

It work really good and it helps kill the bacteria in the water before my family drinks it.

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

The media could not be loaded. 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.

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

Small issue with product that was quickly resolved. If you are looking for UV light to address your water concerns this is the place to purchase from. Highly recommend.

Excellent, this is my second uv ligth form this manufacrurer. They are much better made, although it is 40Wtts and the former one was 55 Wtts. Same 12 gal/min. I don't know if it makes a difference. The built is so much better and sturdier. Installed it and no leaks. Perfect components fit.

Unit installation wasn’t too hard. I did use plumber’s tape as recommended and had no leaks.I did need a replacement quartz sleeve and customer service was great and shipped me two within a few days.
