Make Your Contribution to Saving Our Planet

Save your pocket as well as our Planet: cut your costs dramatically by switching from bottled water to an in-house water purifier and reduce environmental impact of water bottles’ carbon footprint and plastics in the landfills.

How It Works

Mount the system by the kitchen sink, and the purified water will collect in the jug. Insert the jug into the unit's water outlet, and purification will begin automatically. Once the jug is full or removed manually, waterflow will stop.

This system is very easy to use: pure water is within reach whenever you need it. Full jug refill (2L/68 fl.oz.) takes under 7 minutes.

What Makes It Special

Like New Every Day!

Unlike multi-stage in-line filters with cartridges the reverse osmosis system does not absorb and keep dirts inside. The membrane separates clean water from dissolved solids and other rejected particles that go down the drain.

Thus, R.O. system is “like new” every day! It remains clean and delivers safe purified water without the risk of its secondary contamination.

Built-in Booster Pump

Built-in Booster Pump

  • Increases pressure to radically improve the performance and effectiveness of the R.O. unit in all three key areas: increases filtered water flow (production rate), increases rejection rate (improves water purification quality), increases recovery rate (decreases amount of waste water).
  • Prolongs the membrane and pre-filter service life due to increased recovery rate.
  • Performs powerful auto-flush sequence to keep the internals clean and safe.
