I installed the iSpring UVF55FS UV Water Filter on our well supply, and the difference has been night and day: Powerful UV Sterilization: The 55 W lamp neutralizes bacteria, viruses, and other pathogens instantly—no more worry about microbes in every glass. Smart Flow Sensor Switch: The UV only powers on when water runs, extending lamp life and saving energy. High Flow Capacity: At up to 12 GPM, it easily handles simultaneous showers, faucets, and appliances without pressure loss. Whole-House Protection: Every tap—from kitchen to outdoor hose—now delivers clean, odor-free water. Easy Installation & Maintenance: Straightforward plumbing hookups and simple annual lamp replacement make upkeep a breeze. Since installation, that “well water” smell is completely gone, and my wife happily drinks straight from the tap for the first time—no more pre-filtering or bottled water. Room for Improvement: None—this system has worked flawlessly from day one. Highly recommend for anyone on a private well!

Here is my install, it took me about 4-6 hours to install. I leaked tested the unit overnight and I had no problems with the unit. Theres a couple of things to keep in mind when installing, 1. I would encourage you to have a GFCI or something similar when plugging the unit in, water and electricity is really close in relationship with this unit. 2. When installing the Quartz tube be sure not to install the Oring too high on the tube because doing so will bottom out the tube on the stainless cap while snugging up the cap, could lead to a broken tube. 3. I installed a filter after the unit just in case there is any glass breakage, the filter will catch the glass shards instead of going up into the house with the water supply. 4. I would order and have on hand extra supplies such as Orings and Quartz Tubes as well as an extra UV light bulb. I plan on using new Orings while cleaning the Quartz Tube as needed to minimize the chance of leaks. Like I said I have just installed the unit and will report back in a few months after use, I plan on having no issues because the unit as a whole seems to be of excellent quality. The Quartz Tube and UV light parts were packed with a very good foam outer layer and cardboard sleeves for the parts. Instructions are pretty straight forward. So far Customer service has been excellent via email because I just can't find time to call and speak with CS. George Update....here it is 5/16/2025 and the unit is working flawlessly. I'm so glad that I purchased this unit when I did it made an excellent addition to my filtration system. George

I bought the UVF55FS for my rainwater system and it's working great! At first, I thought I'd wasted my money because, after completely flushing my entire system, a coliform bacteria test came out positive. It did it again after a second complete flush. I finally realized that bacteria are pretty sticky and some will inevitably remain stuck to the sides of the pipes, even after multiple attempts to wash them out. So I decided to fill the whole system with a strong concentration of chlorine bleach and I let it stand for 3 hours. Then I flushed the entire system out again until all traces of chlorine odor were gone. I continued using the system for washing but not drinking for a few days then retested for bacteria. This time, the test showed ZERO bacteria. I even let the test incubate for a couple extra days to be sure. One thing I'd recommend is NOT waste your money on the version that I did with the flow sensor. I think the flow sensor is a bad idea now that I've had some experience and more time to think about it. For one thing, the flow sensor will not turn the UV lamp on until flow rate rises to 0.66 GPM. So if you use this mode and you run some water at anything less that this rate, the bacteria-contaminated water entering the UV unit can pass right through without being sterilized. Another problem is that even when the lamp turns on, it will take it a while to come up to full intensity, allowing more unsterilized water to pass through. Yet another problem is that the lamp may not last as long if it's continuously cycled on and off. Therefore, I'm leaving mine on 100% of the time and expect to replace it in 1 year. A few corrections for the manual: On page 4, it incorrectly states the maximum water pressure allowed is 43 PSI. Page 3 apparently has the correct spec which is 85 PSI. It's also stated on page 12: 4 PSI min / 85 PSI max. On page 4, it says to make sure the inlet is at the bottom if you mount the unit vertically because they incorrectly say it will slow down water flow. It won't slow the flow regardless of putting the inlet at the top or bottom. The only way their statement could be true is if the bottom port was left open so water could fall out with no back-pressure. When installed in your home's water system, the difference between pressure-tank pressure and the back-pressure is what determines flow rate, not the orientation of the UV unit. Orientation doesn't effect this at all. On page 8, it says "Mode AUTO is highly recommended to protect the UV lamp.". Not true and definitely NOT recommended. On page 9, it says the "system is designed for continuous operation, and frequent switching will reduce ultraviolet radiation and service life." which directly contradicts the statement on page 8. I believe this statement on page 9 is correct and you should ignore the AUTO mode recommendation. Don't even purchase the version with the flow sensor so you won't have an AUTO mode in the first place! Note that if your home experiences a power outage, unless you use some kind of uninterruptable power supply, your UV sterilizer will be off and any bacteria and viruses can then pass into your potable water system when you turn on a faucet. Mine is on solar with battery storage so is much less of a problem but I still may add a UPS for the UV unit. Lastly, I DO highly recommend this unit after seeing the bacteria test results.

I purchased two of these and within a year the first one had already had leaking issues twice and now the second one does as well. I don't believe one of them ever worked properly as it always beeped as if it wasn't working even after replacing the bulbs. Now after just a year they both leak worse and worse every day at where the brass fittings connect into the electrical system. One of these never worked right and now I'm having to replace both. I do not recommend this product. And before you say I didn't connect properly, I did the plumbing for my entire house with no other leaks. The leak is also were the plastic and metal meet which was a manufactured connection.
