For houses with municipal water sources, this UV light water filter provides a great solution against chlorine-resistant impurities so that you and your loved ones get clean water for drinking, washing, showers and more.

Frequently Asked Questions About This Whole-House UV Water Filter
What Are the Advantages of a UV Water Filter?
A UV filter for whole-house water filtration offers immediate disinfection without tanks, moving parts, and replacing the UV lamp does not change the taste or odor of the water.
Do I Need UV Light for Well Water?
It's definitely a good idea to use a UV filtration system with well water, as private well water isn't treated like municipal water sources are. If in doubt, have your water tested by a professional to find out which contaminants it contains to ensure that you purchase the right filter(s) for your needs.
How Long Does it Take for UV Light to Remove Contaminants in Water?
UV whole-house water filters take just a few seconds to remove waterborne contaminants in water.
How Much Does a UV Water Treatment System Cost?
When you shop with iSpring, you can buy a whole-house UV water treatment system for around $300.
How Long Do UV Water Filters Last?
The device itself should last for many years, but the bulb inside your UV water filter will need to be changed annually, after 9,000 hours of continuous use.
Are UV Water Systems Worth It?
Yes! UV water systems have proven to be quick, reliable, and cost-effective tools for disinfecting water.
Is an RO or UV Water Filter Better?
The best type of water filter depends on the characteristics of your water, and you need not choose just one. If you have a high level of total dissolved solids, a reverse osmosis (RO) filter is a good idea. If you're concerned about microbial contamination, the best UV whole-house water filter will take care of that problem. If you have a problem with sediment or rust in your water, you should add a pre-filter like the iSpring WSP50ARB spin-down sediment filter. You can combine a UV filter with any of our whole-house water filtration systems for an extra layer of protection.

Reviews
We installed a whole house filtration system including the UV filtration system about 9 years ago. The system has worked great and parts are easy to get. Recently we developed a leak on our UV system. I called iSpring and our customer service rep Nick was amazing in helping us out! Our older system has since been updated but he went out of his way to contact the warehouse and find us some of the parts for the older system we needed. Customer service has always been good but Nick went above and beyond to keep us customers happy and reconfirmed our decision in choosing iSpring for our filtration needs.
I bought the UV filter in 2024 and it has worked well until a week or so ago. I heard a beeping coming from the ballast and assumed the bulb needed replacing. I replaced the bulb but a few days later the ballast was beeping again. I contacted support worked with Nick and he was able to diagnose and get me a replacement part sent out. Kudos to iSpring for their great product and for their great support!
My UVF55FS filter came with a house that I purchased. When the ballast started beeping I called the support number on the device. I was happy with the customer support experience! First I was speaking with a live person (Sean) not an automated IVR or AI. Second Sean seemed to be a company employee based in the US not an outsourced call center. Finally the company stood behind their product and sent the replacement parts I needed to get the filter working again. Thank you very much! We are back in business with a working UV water filter in our home.
Water source for my seasonal cabin is an in-ground cistern with water trucked in. Installed the UV55FS in my seasonal cabin with prefiltration using the 50 micron spin down followed by a 5 micron pleated filter about 18 months ago and have been very happy with the results. Got a red blinking light on the ballast a few days ago and Sean at Customer Service was very helpful and sent me a new bulb along with a new ballast and control valve. Bulb did the trick! Comforting to know that the UV Filter notifies you that the bulb needs replaced - will do that annually now. Thanks again Sean!
Have had some whole hose system for almost 2 years now running like a champ. Love the system. Had to recently replace the light as it's starting to go out. Ordered from website bulb ended up getting damaged in shipment called and Michelle took care of it and got me a new bulb out right away. Very happy with the system and customer service.
The UV55W was easy to install and post installation the water potability test results was a perfect set of straight zeros. So it works perfectly to disinfecting the water - I'd recommend installing a drain tap just below the UV55V so that it is easier to maintain also only minor challenge was that it took a couple of attempts that the large 1 NPT need at least 6+ PTFE tape wraps (more than you think!). Also Nick from Customer Service was great help with warranty registration - thanks
I had my UV system's ballast fail. Sean was extremely helpful and authorized a replacement.
I ordered a new lamp and tube for my ispring UV filter and the wrong one got shipped. Sean sent the new unit out right away at no additional cost. I use there products in my water filtration system and highly recommend ispring for your water needs.
I bought this system 1 year ago. The install was straight forward with fundamental plumbing skills. The unit has operated without issue. This system was the only thing that worked for getting rid of coliform bacterial in our well water.I recently ordered a replacement bulb for this system using the QR code printed on the unit. When I received the replacement bulb it was the incorrect model. I emailed customer service and Sean got back to me very quickly and was able to send out the correct replacement for me. The customer service was excellent.
My wife and I bought a second home in the woods with a well and ran into a few concerns about water filtration and purification. We did our research and settled on iSpring buying their UV system and their large 3 stage filtering system. What a differennce and peace of mind we had after these were installed in our well pump house. When we ran into any concerns or questions Nick with iSpring returned my call and knew his stuff. Shortly after the install we did run into a little issue with a brass fitting leaking. One call to Nick and he sent a replacement part out asap. I grew up drinking tap water and now I have peace of mind in our new getaway home. It also helps keep the hot water heater clean of debris and other water needs to prolong the heater's useful life.
Was an easy addition to my ispring filter system. Came in damaged and the install instructions were complete and easy to understand
The installation was easy if you have knowledge of plumbing fittings. The reason for my inspection was bacteria detected in a community holding tank.After the UV system was installed my water test came back bacteria free. Perfect
I have used this system for the last 5 years at my seasonal off-grid lake cabin where we draw water from the lake. Nick has been so helpful with resolving any issues we have had and helping me figure out what products I need to purchase whenever there is a problem including replacing parts. His help has been invaluable.
Sean at customer service provided professional courteous & expeditious service when the flow switch developed a slow weeping leak. New flow switch & ballast received and installed. Thank you Sean.
Nick was very helpful and thorough. He determined that my UVC ballast with flow sensor needed to be replaced and that it was under warranty. Fantastic customer service!
I installed a UVF55FS UV light recently (2025). After about a year the light became inoperable (not the light bulb). Nick from iSpring accurately diagnosed the problem and sent the replacement part the same day. Thanks iSpring for providing excellent product support.
Great water filter system and great customer service. Sean is especially very helping and provided replacement system when our system got issues. I highly recommend the system.
Nick is absolutely top notch. Available to answer all questions and even reviewed install photos to ensure we had the proper setup. Our water has never tasted and smelled so good. Thanks Nick and iSpring for being awesome!
System works well and Nick and Sean have been a great help re-ordering parts :)

I had ordered this unit two separate times on Amazon and both times it arrived from UPS with the boxes torn open and parts missing. I then decided to order it from iSpring directly who had it delivered by FedEx. It was double boxed with bubble wrap between the inner and outer box and was in perfect condition all parts intact! I have yet to hook it up but it looks like a solid unit that will do what it is designed to do. Thank you iSpring for shipping FedEx and for packaging it so well.
I have purchased two UVF55FS iSpring UV filters and both work great. The filter's design makes it easy to assemble and install. I had trouble with the web site and called iSpring's customer support team. I spoke with Michele and she was able to quickly get my order shipped directly to me. Thanks for your excellent product quality and exceptional service.
I love my iSpring UV system. I had a little problem and Sean was super helpful in resolving it! I would highly recommend this company and their products. We live in the Virgin Islands and our main source of water is from cistern water catchments. So we drink the water and you need a quality filtration and UV system and this is perfect!

After my ballast went out I didn't know what to do. A short call to Sean and I understood what was wrong and he got a fix in the mail to me within minutes.Thank you Sean!I will be doing more with iSpring in the future.
I had a great experience working with Francis. I purchased from Home Depot super easy install. After a few weeks I had a ballast issue. I reached out via the website/warranty question. Francis responded with in the hour sent me a new part and I was up and running. Some of the best customer service i Have experienced in a long time.
Great product has reduced the bacteria in my well water. Easy to install. Great customer service
