RO Water Purifiers in Bangladesh

Reverse osmosis purifiers from Water Filter Service remove dissolved salts, arsenic, lead and other heavy metals to give you pure, great-tasting drinking water.

RO is the most effective choice for tube-well, high-TDS and salty water — the most common water problems in Bangladesh.

How does an RO purifier work?

After sediment and carbon pre-filters, water is pushed through a semi-permeable RO membrane that blocks up to 99% of dissolved impurities. Post filters then polish the taste and can add back minerals.

What RO removes

  • Dissolved salts (TDS) — for fresh, non-salty taste.
  • Arsenic & heavy metals — lead, mercury and cadmium.
  • Bacteria & viruses — blocked by the fine membrane.
  • Chlorine & odour — removed by carbon stages.

Features to look for

  • Stages — 5–7 stage systems with mineral or alkaline post filters.
  • Capacity — 75–100 GPD for homes, higher for offices.
  • Hot & cold option — for instant hot and chilled water.
