Updated 400GPD & 2.5:1 Pure to Drain Ratio

Our tankless reverse osmosis system offers faster water flow, reaching up to 600 GPD. It can fill a 200ml cup of water in just 7 seconds, providing instant access to clean, filtered water. The 2.5:1 pure to drain ratio allows you to save up to 250% more on water bills compared to other 1:1 reverse osmosis filters. This system offers an economical alternative to bottled water and is environmentally friendly, as no tank means no secondary pollution.

Premium 7 Stages Filtration

Our RO water filtration system has 7 stages, reducing over 1,000 contaminants and improving the taste of your water. The RO filter (3 stages) and PPC filter (4 stages) use a 0.0001-micron reverse osmosis membrane to decrease TDS from 500 ppm to 15 ppm, intercepting sand, particles, salt, PFAS, radioactive substances (Radium), fluoride, heavy metals, vinyl chloride, ethylhexyl acrylate, isobutylene, and ethylene glycol, ensuring you get the purest water possible.
