6-stage water filter: why you need it and how it works

Samarkand water is high in lime and salts — causing problems from kettle scale to kidney stones. A 6-stage reverse osmosis filter purifies water almost to distilled level, then enriches it with healthy minerals.

What each stage removes

Stage 1 traps sand and rust, stages 2–3 (carbon cartridges) absorb chlorine and organics, stage 4 — the osmotic membrane — blocks up to 99% of heavy metals, salts and bacteria, stage 5 improves taste, and stage 6 — the mineralizer — returns calcium and magnesium to the water.

How is it different from a regular filter?

Pitcher filters and simple flow filters only trap mechanical impurities and chlorine — salts and heavy metals stay in the water. Reverse osmosis purifies water at the molecular level, which is why RO systems are the gold standard for drinking water.

Where can it be installed?

The system fits compactly under the kitchen sink and dispenses water through a separate tap. Higher-capacity models are available for offices, schools and cafés. Installation takes 2–3 hours.

BMS Group installs filters in 1 day and offers a cartridge replacement service. The AQUA STREAM RO-6 from our catalog is our most popular model.
