How did we get our start?
Back to 2016, we find most of the UV water purifiers are unaffordable for the families. And if you live in a rural place or small town/city, it would be difficult to get clean water directly from the pipes/wells/raining water. Then, HQUA was established, we aim to provide people, affordable, reliable, responsible products, and services for the water issues.
What problem are we solving?
All our products focus on water issues, which mainly include indoor drinking water treatment issues, as well as outdoor pond water circulation, decoration, and swimming pool equipment.

Handy –
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.

Good product, great customer support
This is a very nice system. Simple and straight forward, and looks to be well made. The threads on the inlet and outlet ports are good matches to the pex connectors I used, and sealed perfectly with a little bit of teflon tape.But the thing I really like is their tech support. I had a small issue after installing it, and emailed them Saturday morning around 7:30 am, expecting to get a reply on Monday or so, but a representative named Irene replied within 2 hours and resolved the issue for me within 5 minutes.Irene was very pleasant and helpful, and immediately addressed the issue I asked about.I would highly recommend this system and this company.

Myexperience with product
I overall liked the product. It came well wrapped and had easy instructions. I was surprised by the number of water shutoff valves 5 you are supposed to install. I only had room for 4. I followed the instructions word for word and everything went well until I turned the water on. I had a small leak at the bottom fitting of the housing unit. Since my unit used soldered copper connections, I had not choice but to start over. I could not get it to stop leaking. nylon tape and pipe goop did not work. I finally figured out a solution: I had an extra wax ring for a toilet and I used some to half fill the stainless fitting. It worked like a charm. wax is perfect for toilets, so why not screw in fittings. Anyway, Overall I am pleased.

Broken bulb. Not a user friendly in design
One of the bulbs came broken. It was packed beautifully so it had to be broken at the manufacturer not during shipping, thankfully it came with 2 bulbs. I have reached out to the manufacturer 2 days ago and have not heard back yet. The design is not very user friendly. In order to plug in the bulb you need to plug it in before inserting the bulb. Otherwise you risk breaking the bulb there is no way to see if it is lined up if you donât plug it in first. It worked out for installation but when it comes time to replace the bulb it is going to be a pain.

Amazing Product. Very fairly priced.
The product was packaged amazingly to prevent damage. Any company that would invest that much time and money into making sure you get their product in good condition shows there pride in what they have built. They even included an extra bulb. BUY IT!

Failed the water test, installed this test cam back perfect! As soon as it was ordered seller sent an email with contact info to reach them if there are any issues stating they would replace any missing or damaged parts with 2 parts. No issues came up , easy to install, no leaks and works great would recommend buying from this seller!

I added this to my water filters and passed the water test with flying colors.
