OnlyPure FastPure 1000™
Tankless Alkaline Reverse Osmosis Water Purifier
The OnlyPure FastPure 1000™ is a high-performance tankless alkaline reverse osmosis water purification system designed for modern homes and light commercial environments that demand speed, purity, efficiency, and balanced mineral water—all in a compact, space-saving form.
Equipped with an advanced 1,000 GPD reverse osmosis membrane, FastPure 1000™ delivers purified water instantly at a powerful flow rate of up to 0.69 gallons per minute (2.6 L/min). Its tankless architecture eliminates bulky storage tanks, ensuring water is always freshly filtered while preventing secondary contamination commonly associated with stagnant tank systems.
The system utilizes a multi-stage filtration process through a high-capacity PCT composite pre-filter, precision RO membrane, and a built-in alkaline remineralization stage. This process effectively reduces chlorine, odors, sediment, dissolved solids, and other common contaminants, then restores essential minerals to produce clean, smooth, and naturally alkaline water with improved taste and balance—ideal for drinking, cooking, coffee, and ice.
Engineered for sustainability and efficiency, FastPure 1000™ features an advanced 2:1 pure-to-drain ratio, significantly reducing wastewater compared to conventional RO systems. An automatic membrane flushing system continuously rinses the RO membrane to maintain peak performance, extend filter life, and ensure consistently fresh water output.
User convenience is at the core of the design. A smart filter reminder system clearly indicates filter status and replacement timing, while the tool-free rotate-and-pull cartridge design allows filters to be replaced in approximately 3 seconds, making maintenance fast, clean, and effortless.
The integrated one-piece water manifold module minimizes internal connections, reducing leakage risk and enhancing long-term system reliability. With a wide 110–240V power compatibility, FastPure 1000™ is suitable for residential and commercial installations worldwide.
Combining high output, alkaline water benefits, intelligent engineering, and elegant design, the OnlyPure FastPure 1000™ is an ideal solution for premium households, offices, cafés, clinics, and hospitality environments seeking fresh, mineral-balanced water on demand.
