  • Tankless/Electricity-Free Design: GLACIER FRESH GFU03 tankless reverse osmosis system features an integrated tankless design, saving up to 70% of under-sink space. Unlike other electric systems, it is water-powered, requiring no electricity and thus avoiding electrical safety hazards and operating noise. Suitable for any under-sink installation environment.
  • 5-Stage Filtration: Under sink reverse osmosis system meets NSF/ANSI 58 and 372 standards, employing a precise seven-stage filtration system to effectively remove over 1000+ harmful contaminants, including PFOA, PFOS, chlorine, lead, fluoride, and heavy metals. Ensuring every drop of water is pure, safe, and odorless, providing a clean drinking experience.
  • 0.0001 μm RO Membrane: The GLACIER FRESH Reverse Osmosis Water Filter features a high-precision 0.0001μm RO membrane, effectively filtering impurities larger than 0.0001μm to ensure unparalleled water purity. This advanced technology not only guarantees clean drinking water but also delivers a refreshing and sweet taste.
  • 800 GPD High Flow: The Reverse Osmosis Water Filter boasts a high flow rate of 800 GPD, filtering a cup of water in just 5 seconds, perfectly meeting the pure water needs of a large family. An external water pressure gauge monitors water pressure in real time, protecting the system for normal operation.
  • 3:1 Pure to Drain Ratio: The Tankless Reverse Osmosis System boasts an impressive 3:1 wastewater ratio, producing only one cup of wastewater for every three cups of purified water filtered. This not only saves you money but also reduces water waste and promotes sustainable development.
  • 30 Minute Quick Installation: Undersink Water Filter Systems can be installed in just 30 minutes, half the time required for traditional tank-type systems (2-4 hours). All necessary adapters and tool-free connectors are included. Note: This product requires drilling a 1/2"-1" diameter hole in the sink to prepare for faucet installation.
  • Easy-Replace Filter: The filter cartridge features a pull-out design, allowing for replacement in just 3 seconds. To replace the cartridge, simply turn off the tap; there's no need to shut off the water valve. Note: After initial installation and each cartridge replacement, rinse the filter cartridge with running water for 10-20 minutes.
  • Please measure your cabinet dimensions to ensure that the cabinet size is larger than the product size. The product size is 13.58” x 8.27” x 16.54” (345x210x420mm)
