iSpring UVF55FS 55W Whole-House UV Water Filter With Smart Flow Sensor Switch, 120V, 12 GPM
About this item
- This iSpring whole-house UV water filter is the ideal last step to add to your water filtration system to give you confidence that you can trust the quality of your water.
- Water's long dwell time inside the 37.5-inch reactor chamber ensures adequate treatment, while the 12 GPM flow rate minimizes pressure loss with a 1-inch MNPT inlet/outlet design.
- The high-quality 55-watt UV lamp is housed inside a durable quartz sleeve and has a lifespan of up to 9,000 hours.
- The upgraded 55 W/120 V ballast has a smart flow sensor switch that turns the UV light on and off automatically as needed, and the multi-mode control switch makes it easy to adjust and monitor the performance of the system. The sensor will only kick on when the flow rate reaches 0.66 gallon/minute (2.5 L/m).
- Mounting clips are included with your delivery for easy DIY installation. Maintenance is also simple: Just clean the quartz sleeve every six to 12 months and replace the UV lamp annually.
- UV filtration is chemical-free, reliable, and affordable. It's also an eco-friendly alternative to chlorine treatments, creating no water treatment byproducts and requiring very little power consumption.
- This product comes with a 30-day money-back guarantee, an extended manufacturer warranty upon registration, and lifetime technical support from iSpring Water Systems.

I recently purchased an iSpring UVF55FS Whole House UV Water Filter with Smart Flow Sensor Switch, 55W on June 16, 2023. This was professionally installed by a licensed plumber and the photo below was shared with iSpring technical support who confirmed that the system was correctly installed.
Over the last 4 months I have had to replace the UV bulb three times. I have contacted iSpring to address the problem and asked them to replace the control module and fused bulbs to try and correct this problem. Right now the system is down and I cannot be replacing the bulbs every few weeks. It’s running in Auto mode so turns on only when the water is flowing.
I am waiting for iSpring to help since I’m very disappointed and frustrated with this system. As you can see from the photo I purchase a lot of iSpring products and have never had this type of problem before.
