About This
- Affordable Replacement Filters: Our replacement filters are priced competitively, ensuring you get high-quality filtration without overspending. Choose the F4RO5004F 1-year pack or the F9RO5004F 2-year pack for long-term savings and hassle-free maintenance.
- 1000+ Contaminants Removal: Independently tested by SGS for PFAS and TDS reduction. This tankless reverse osmosis water filter eliminates over 99% of 1,000+ harmful contaminants, including PFAS (PFOA and PFOS), vinyl chloride, chlorine, fluoride, lead, arsenic, asbestos, calcium, sodium, and others.
- 6-Layer Filtration with UV Protection: This reverse osmosis water filter features an advanced 6-layer filtration system, including a PP sediment filter, anti-scale filter, CTO, 0.0001-micron RO membrane, taste-polishing CTO filter, and a built-in UV light that lasts up to 8,000 working hours. The water filter for sink also includes a status indicator to monitor UV function, ensuring safe and clean water.
- Tankless Design for Space-Saving: This reverse osmosis system under sink saves valuable under-sink space by eliminating the need for a storage tank.
- Built-In Pump for Low Water Pressure: The RO5004F includes a pump that addresses low water pressure, enhancing RO membrane efficiency for faster water output. The pump operates quietly for a more comfortable experience.
- 500 GPD High Flow Rate: The water filter reverse osmosis provides 500 gallons per day, more than 5x the flow of traditional RO systems. It can fill a cup in just 10 seconds, ensuring a continuous clean water supply for drinking and cooking.
- Easy Filter Replacement with Smart Monitoring: The simple twist-to-unlock design makes filter changes quick and easy, while the integrated filter life indicator provides automatic replacement reminders and self-cleaning features to prolong filter lifespan and maintain optimal performance.
- Leak-Stop Valve for Extra Safety: Although the RO water filter system undergoes rigorous leak testing to ensure reliability, we’ve added a built-in leak-stop valve as an additional safeguard. In the unlikely event of a leak, the valve automatically shuts off the system, providing extra peace of mind.
- Quiet Experience: Equipped with a sleek and durable casing, the under sink water filter system offers a more organized structure. It also helps reduce operational noise, providing a quiet experience and a clean, refined appearance.
