Product ranges
Five ranges, one philosophy: keep it simple
From under-sink RO to whole-house stainless steel UF — every KomiBright system is designed to install easily, run without power, and maintain itself with one yearly filter change.
Why KomiBright
Less does more
Zero electricity
Runs on municipal tap pressure from 1.5 bar. No pump to fail, no socket needed, no noise.
One filter a year
A super compound filter replaces the usual 3–5 cartridges. Swap it — and the membrane — once a year.
DIY installation
Modularised waterways and no redundant fittings: install and maintain it yourself, no technician.
Patented & controlled
Original designs and patents, with IQC / PQC / OQC control from raw material to export.

Reverse osmosis, minus the pump
RO needs pressure, not power. Self-stabilising valves, an integrated flow restrictor and a low-resistance waterway let ordinary tap pressure push water through a 0.0001 μm membrane — and even flush the membrane automatically.
- Auto membrane flushing without power
- One housing, multi-membrane function
- Food-grade PP5 materials throughout
About us
A factory obsessed with simplicity since 2009
RO makes the cleanest water, but traditional machines are hard to install, rely on failure-prone pumps and juggle multiple filters. KomiBright was founded to fix exactly that — following the KISS principle: Keep It Simple, Stupid. Today our products serve users in nearly 30 countries.
FAQ
Questions, answered
How can a reverse osmosis system work without electricity?
Reverse osmosis only needs pressure, not electricity. Conventional RO machines add an electric booster pump; KomiBright systems are engineered with innovative self-stabilising valves, an integrated flow restrictor and a low-resistance waterway so that normal municipal tap pressure (from 1.5 bar) is enough to push water through the 0.0001 μm membrane.
What water pressure do I need?
C25R-series systems run on 21–70 PSI (1.5–5 bar). The KB-C100R direct-flow system needs 30–70 PSI (2–5 bar); with 3 bars of tap pressure it needs no pump kit at all. If your pressure is lower, a pump kit can be added.
How often do filters need replacing, and can I do it myself?
Once a year — that's the whole maintenance schedule. One compound filter and one membrane, both designed for tool-free replacement in minutes. No technician visit needed.
