Expert MOD600

Next Generation Tankless On-Demand Reverse Osmosis Water Purifier With Auto–Flush


Tankless Drinking Water Filtration Systems are rapidly replacing ordinary water filters all over the world

1. Safe and clean water. It will provide you with safe and tasty drinking water guaranteeing 100% protection from any known viruses (including COVID-19) and bacteria. As it is a direct flow system, it means you don’t need a tank for water. Thus, no risk of any bacterial growth exists when water stored in a tank for a long time (more than 1 month).

2. Significant savings for the family budget in comparison with bottled water and ordinary water filters. Our direct flow system needs 4 times less water for producing drinking water than previous generation water filtration systems with a tank! 

3. No risks associated with plastic containers. Our system will eliminate all the risks of long-term storage of drinking water in plastic containers, e.g. bacterial growth during prolonged storage; heating of plastic bottles during summer and the use of prohibited plastic.  

4. Space-saving/Easy installation in 20 minutes/Modern Design. The system consists of the most compact installation since a tank is not needed. It is a beautiful modern design.


Your Key Benefits

Save on your every utility bill!


Modern Innovative Technology

• Direct flow R.O. filtration in real time, no storage tank required
• Fully automatic operation
• Compact and modular


Lower Cost of Ownership

High efficiency rate leads to a less frequent filter change necessity.

The more you use your R.O. machine the more you save on maintenance!

This direct flow reverse osmosis water filtration system saves tons of water wasted per year and solves maintenance and water quality issues with tank based systems.

Read on and discover how you can carry out high level purification without such an economic and environmental impact.
The future of reverse osmosis is tankless.

About R.O. Filtration

Reverse osmosis is currently the most advanced yet natural method of water purification. Semipermeable membrane allows only water to pass through and rejects everything else.

These days the human genius reproduced this natural process in a highly sophisticated nanotechnology device right at your sink.

R.O. treated water is free from chlorine, heavy metals, other dissolved solids and ions, bacteria and viruses. This water is safe and refreshing, requires no boiling and is a good choice for all kind of use including newborn baby feeding.

No magic, no unproven claims – just pure science! Reverse osmosis is used everywhere when real clean water is needed, not claims: from pharmaceutical production to space station water supply, from multi-million population area municipal water desalination plants to marine ship rescue kits.

Make no mistake, this osmosis process is as much natural as it can be since it’s essentially the same as the one in every living cell on Earth. Cell membrane allows only what it needs to get through and rejects everything foreign.

Beyond Bottled Water Quality

  • Expert MOD600 tankless reverse osmosis system delivers virtually unlimited amount of safe, clean and joy inducing water right at your home, every day.

  • No need to transport and dispose of bottled water any more!

  • Great for drinking, ice makers, beverages, coffee & tea, food preparation & cooking, sports, etc.

  • This R.O. system removes odor and most harmful substances such as heavy metal ions and total dissolved solids from tap water making it tasty, fresh and vital. It delivers a pure, refreshing experience with no aftertaste of heavy metals, limescale or chlorine.

How It Works

The system usually mounts under the kitchen sink with the purified water faucet been installed on the sink or deck. An available on the market combo tap with built-in waterway for filtered water can also be used.

To get fresh and clean water instantly just open the faucet, and everything else will be performed automatically.

Install in Five Easy Steps

Expert MOD600 is easy to set up using basic tools and included accessories.


Position the System.

This system naturally mounts under the kitchen sink but also can be installed near other points-of-use: in a cellar, garage or utility room. The unique feature of the system is a possible “split-installation”: install the pump box unit up to 50 feet away from the R.O. unit itself. You may place both units under your kitchen sink, or you may place the R.O. filtration unit under the kitchen sink near the faucet, and the pump box unit in a bathroom near the electrical outlet, cold water supply and drain pipes.


Install the Filtered Water Faucet.

It can be installed in an existing hole of soap dispenser or water sprayer, or in a new hole in the sink or deck. An available on the market combo tap with built-in waterway for filtered water can also be used.


Install Drain Saddle on the Drain Pipe.


Install Adapter Ball Valve to Feed Water to the System.


Connect the Tubes and Start Up.

All internal tubes are already factory pre-installed. You only need to connect few external tubes, such as water supply, faucet and drain tubes by following the enclosed chart.
Then turn on the system, make quick initial washing and start enjoying safe, clean and tasty water.

Tip: Expert MOD600 R.O. System may also be used with an optional tank if you prefer! Storage tank can be added easily, at any time, even after installation of the system itself.
