• Usage note: This UV unit is intended for pre-filtered water only and is not recommended for whole-house systems or untreated well water. Using untreated water may cause scale buildup, which can affect UV performance.
• Final-stage UV treatment: Designed as an add-on final disinfection step and compatible with most RO systems, under-sink filtration systems, and RV water setups—adding UV treatment 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 testing reports up to 99.9% reduction of harmful substances under specified test conditions.
• Smart, durable LED UV design: A built-in flow-detection system turns the LED UV on when water flows and off when it stops to help reduce unnecessary power use. LED UV technology avoids fragile glass tubes and ozone-related concerns, with the light housing supported by a 50-year durability assurance.
• Stainless steel housing & easy install: Features a stainless steel body and has passed safety evaluations (including FCC EMC testing). Installation typically requires no pipe cutting, and the included 1/4"–3/8" adapters plus a standard three-prong plug help ensure compatible with most under-sink water lines and filtration systems.
