ISpring UVF55FS Whole House UV Water Filter with Smart Flow Sensor Switch, 55W

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). 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.
