• ‌Important Use Notes: Not suitable for whole-house water filter systems or untreated well water. This UV unit is intended for pre-filtered water only; using unfiltered/untreated water may lead to scale buildup that can reduce UV performance.
• Final-Stage UV Add-On: Designed as an under-sink final-stage UV treatment unit that can be added to many RO systems, under-sink filtration setups, and RV water systems without replacing your existing filters.
• Flow Rate Guidance & Tested Results: Recommended operating flow rate is below 2 L/min (0.53 GPM) to support adequate UV exposure time. Third-party laboratory testing reports up to 99.9% reduction of targeted harmful substances under specified test conditions.
• Automatic On/Off Operation: An intelligent flow-detection system turns the UV light on when water flows and off when flow stops, helping reduce unnecessary power use and supporting longer module life.
• LED UV Design, Housing & Easy Install: Uses LED UV technology (no fragile glass tube and no ozone-related concerns) in a stainless-steel housing designed for under-sink conditions. The unit has passed safety evaluations including FCC EMC testing. Installation requires no pipe cutting and includes 1/4"–3/8" adapters plus a standard three-prong power plug for compatibility with many under-sink water lines.
