Clean and safe drinking water is a growing concern in Dhaka and its surrounding areas. Whether you live in Mirpur, Banasree, Rampura, Moghbazar, or other parts of the city, your tap water may contain dissolved solids, heavy metals, bacteria, and other impurities that ordinary filters cannot remove.
WaterMan BD has helped thousands of households find the right water treatment solution, from simple filters to advanced RO systems, based on real water conditions in Bangladesh. To understand why RO purifiers cost more than Direct Flow or UV systems, it’s important to look at the advanced technology and multi-stage processes that make RO water purification so effective.
RO Multi-Stage Water Purification Process
Most Direct Flow and UV purifiers focus on basic disinfection, usually killing bacteria and viruses, but they do not remove dissolved solids such as minerals, salts, or heavy metals. RO purifiers, in contrast, use a multi-stage filtration process that includes sediment filters, activated carbon, a high-quality RO membrane, mineralizers, and post-filters. This allows RO systems not only to disinfect water but also to remove Total Dissolved Solids (TDS) and harmful chemicals, which is a key reason they cost more.
In Bangladesh, many deep tube wells and municipal water sources in urban areas have fluctuating TDS and arsenic levels, contaminants that only RO systems can reliably remove.
The Key Component Behind Pure Drinking Water
The heart of any RO system is its RO membrane, a high-precision filter that allows only clean water molecules to pass through while blocking dissolved impurities. Unlike UV and Direct Flow systems, which do not reduce TDS, RO membranes can remove a wide range of contaminants commonly found in Bangladesh water supplies, including heavy metals, salts, and harmful chemicals. This advanced technology ensures that your water is safe, clean, and tastes fresh, though it comes at a higher cost.
- RO membranes are essential for removing Total Dissolved Solids (TDS).
- Can filter heavy metals, salts, and other harmful chemicals.
- Require high-quality materials and precision manufacturing, increasing cost.
- Need periodic replacement to maintain optimal performance.
- Provide safe, clean, and great-tasting water for households in Bangladesh.
Additional RO Components and Cost
RO systems include several extra components that make them more advanced and reliable compared to Direct Flow and UV purifiers. These components ensure efficient purification, safe operation, and constant availability of clean water, which is especially important for households in Bangladesh facing power cuts or irregular water supply.
| Features | RO Systems | UV & Direct Flow Purifiers |
| High-Pressure Pump | Included | Not included |
| Storage Tank | Included | Not included |
| Auto Shut-Off Valves & Sensors | Included | Not included |
| Continuous Water Availability | Yes | Only when power is on |
| System Complexity | High | Low |
These additional components make RO systems more reliable and capable of providing safe, purified water at all times, which explains why they cost more than UV or Direct Flow purifiers.
Benefits of RO Drinking Water
The true value of an RO system becomes clear the moment you drink the water. Beyond basic purification, RO systems improve taste, protect household appliances, and support overall health. These benefits are especially important in areas of Dhaka like Mirpur, Banasree, Rampura, Mohakhali and Tejgaon where residents often face water quality issues, including high TDS, hardness, and contaminants.
- Provides better taste for drinking water
- Prevents scale buildup on kettles and other appliances
- Reduces skin and hair irritation caused by hard water
- Offers peace of mind knowing your family is protected
- Addresses common water quality challenges faced by residents in Dhaka
An RO water purifier ensures that households in these areas have consistent access to safe, clean, and great-tasting water, making it a long-term investment in health and daily convenience.
