GLACIER FRESH GFU03 Electric-Free Reverse Osmosis Water Filter 800 GPD | Non‑Electric, 3:1 Pure to Drain, 5-Stage Under Sink RO Water Filter System, Reduces PFAS, Lead & TDS, 0.0001μm RO Membrane

• TankInside Design: GLACIER FRESH GFU03 internal tank reverse osmosis system adopts a water‑powered structure, no electricity needed, zero operating noise. All‑in‑one design without external water tank saves up to 70% of under‑sink cabinet space, no more bulky external storage tank. Eliminates electrical safety hazards and fits most under-sink setups.
• 5-Stage Filtration: Under-sink Tankless reverse osmosis system meets NSF/ANSI 58, 372, and 401 standards, employing a precise multi-stage filtration system to effectively remove over 1000+ harmful contaminants, including PFOA, PFOS, chlorine, lead, fluoride, and heavy metals. So every drop is clean, safe, and fresh-tasting, for a cleaner, better-tasting drinking experience.
• 800 GPD Fast Flow: 800 GPD high flow delivers a cup of purified water in only 8 seconds to satisfy large‑family water demand (1 cup/8 oz). Built‑in real‑time water pressure gauge safeguards system stability. Note: The actual water output rate depends on the inlet water pressure. It is recommended that the water pressure be at least 40 PSI; otherwise, the flow rate will be low.
• 3:1 Pure-to-Drain Ratio: The GFU03 Tankless Reverse Osmosis System features an impressive 3:1 pure-to-waste water ratio—producing just one cup of wastewater for every three cups of purified water—far more efficient than systems with 1:1 or 1:2 ratios. This not only saves you money but also reduces water waste and supports more sustainable water use.
• 30 Minute Quick Installation: This undersink water filter system can be installed in just 30 minutes, half the time of traditional tank-style systems (2–4 hours). Includes all adapters and tool-free connectors. 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 has a pull-out design, so it can be replaced in just 3 seconds. To replace the cartridge, simply turn off the faucet—no need to shut off the main water supply. Note: After initial installation and each cartridge replacement, rinse the filter cartridge with running water for 10-20 minutes.
• High‑Precision 0.0001μm RO Membrane: Equipped with premium 0.0001μm RO membrane, filters out ultra‑fine impurities for outstanding water purity. Advanced membrane technology brings clean, sweet‑tasting drinking water for your whole household.
• Check Cabinet Space Before Installation: GFU03 measures 13.58" L × 8.27" W × 16.54" H (345 × 210 × 420 mm). Please measure your under-sink space and leave extra room for water connections, tubing, and filter replacement.
