Important Note: It is important to maintain the quality of your system by using only genuine RainSoft replacement filters and cartridges. When “made-to-fit” alternative filters and cartridges are placed into your RainSoft Ultrefiner II Premium Drinking Water System, the product warranty will become null and void and the system will lose its NSF certification. To guarantee proper operation and certification of your RainSoft Ultrefiner II Premium Drinking Water System, please use genuine RainSoft parts.
5 Micron Sediment Filter
Engineered for superior filtration, your system is certified to reduce Total PFAS, Microplastics, Cysts, Lead, Chlorine/Chloramines, Volatile Organic Compounds, and more - giving you peace of mind with every sip. The pre-filter removes particles and sediment as small as 5 microns in size from the water supply.
The pre-filter requires periodic replacement every 6 to 12 months and protects the Membrane from harmful contaminates. Your water quality and water usage may affect this replacement schedule.
