Reverse osmosis that runs on line pressure alone — with one cartridge to change, not three.
- No electricity
- One cartridge
0W
Power draw
The under-sink and commercial range runs on the pressure already in the mains. The A95R is the deliberate exception.
1cartridge
To replace
Sediment and carbon in one combo cartridge, where a conventional system uses three.
800ppm
Feed water
Maximum dissolved solids the membrane will take from a municipal supply.
30countries
In service
Systems installed with users in nearly thirty countries worldwide.
Configured for the room it lives in
Four stages, no moving parts
Mains pressure does the work a pump does in a conventional reverse-osmosis system. Nothing in the chain below needs power, and only two parts of it are ever replaced.
- 01 / 04
Line pressure in
Tap pressure does the work. The range starts working from 1 bar, below most mains supplies — no pump, no socket.
- 02 / 04
Sediment and carbon
One cartridge, the Combo filter (F-210), takes out grit, rust and the chlorine that would wear the membrane.
- 03 / 04
The membrane
The membrane lets water through and sends dissolved solids to drain. Feed water must stay under 800 ppm.
- 04 / 04
Out to the tap
Into a tank and a dedicated faucet, or straight to the outlet on direct-flow models. The model decides which.
Trust and proof
Who makes it, what the papers say, and how it is installed. Everything a distributor checks before an order, published rather than promised.

One system per room, out of nine.
The range splits by where the water is drawn and how hard it is worked. These four are the starting points; the finder narrows the rest.

Serviced in a twist.
The housing takes the system's whole working pressure, and the cartridge inside it twists out by hand. A service visit is a cartridge change, not a repair.
Reverse osmosis, without the pump.
For kitchens, bars, restaurants and laboratories — and one model for water with no mains.
Why KomiBright is different
A conventional pumped system beside the under-sink and commercial range, line by line.

Nine systems, four rooms. One of them is yours.
