Review: Excellent add-on UV sterilization for whole house water filtration! - I bought the iSpring UV sterilizer to add to my iSpring whole house water filtration system, a WGB32BM 3-stage system. The installation of the UV sterilizer is pretty straightforward. I used 1" Pex-B with clamp style fittings, to match the 1" of the filter system. The system is exactly what I was looking for and performs as expected. As shipped by desertcart via FedEx, the UV bulb arrived shattered, and the damaged package was also missing the o-rings, but the rest of the system was ok, and I did not want to return the whole system. Luckily, desertcart was able to issue a partial refund for just the value of a replacement UV bulb. I ordered a replacement bulb and it arrived within a few days, this time undamaged. I also emailed Nick at iSpring customer service about the missing o-rings, and he immediately responded by email and shipped out a replacement set of o-rings which arrived very quickly via USPS. I call that very prompt and excellent customer service! A few more notes on the system: it has a smart controller with the bulb ballast integrated. This controller connects to the UV bulb, to the AC power, and also to the flow switch to turn the UV bulb on as soon as water flows. This is indicated by a green LED. When flow stops, the controller keeps the UV bulb on for another 5 min (300 sec) to avoid excessive bulb power-ons, which would reduce bulb life. After 300 sec, the bulb is turned off and this is actually shown via a 3-digit LED count-down on the controller, a nice feature! If within 300 sec the water flow is turned back on, the counter is reset to 300 sec. Overall, I really like this flow-through water sterilization system. It has a very high build quality, and is easy to install, and works in a fully automated, worry-free way. I would highly recommend this as an add-on to any home/whole house water filtration system.
Review: Great product, great company with great people - Over a year into owning this- We have be very impressed with our iSpring whole house UV filter/sanitizer. It was easy to install and set up and swapping bulbs when it’s due is very easy too. And it works! It has taken care of the issues we had with our well water and been very reliable. The customer service and support is fantastic as well. Jonathan has helped us get and keep the system going. He’s great! You get a real person, here in the USA, with personality and good communication when you call. Highly recommend this product and company.

### ⭐⭐⭐⭐⭐ Great UV Sterilizer!
*by L***L on March 27, 2023*

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.
