Description
The Nobana 1000GPD Tankless RO system is a high-output, tankless under-sink water purifier for households that use a lot of drinking and cooking water. With a rated capacity of around 1,000 gallons per day, it delivers purified water on demand at a fast flow rate, so filling a large pot or a kettle takes seconds rather than minutes. There is no storage tank, which saves cabinet space and means water is always freshly filtered.
How the 5-stage system works
- Sediment filtration – removes sand, rust and particles.
- Activated carbon – reduces chlorine, taste and odour.
- Carbon block – finer chlorine and organics removal to protect the membrane.
- High-flow RO membrane – removes dissolved salts, heavy metals and microorganisms.
- Post carbon – final taste polishing.
Exact cartridge layout can vary by model; some versions combine stages into composite cartridges.
Key features
- Rated around 1,000 GPD for very fast flow
