Living in Dhaka means dealing with unique water challenges. From high levels of dissolved salts (TDS) and hardness to the constant threat of bacterial contamination, the water from your tap isn’t safe to drink. Investing in a reliable water purifier is a critical decision for your family’s health.
With several prominent brands in the market, how do you choose? Three names you’ll often see are Deng Yuan, Kent, and Ecosoft. Each has its own approach to water purification.
At WaterMan BD, we believe in providing you with the facts. This detailed comparison will break down the key features of all three brands to help you understand the technology and make an informed choice that fits your home’s specific water conditions.
Head-to-Head Comparison: Features at a Glance
We’ve expanded the comparison table with more parameters that matter to you.
| Feature | Deng Yuan | Ecosoft | Kent |

| Best For Water Type | High TDS Water, Heavy Metals, Dissolved Salts | Moderate TDS, Municipal Supply, Bacterial Contamination | High TDS Water, Bacterial & Viral Contamination |
| Mineral Retention | Good (Often includes mineralizers) | Excellent (Natural, no electricity) | Good (TDS Controller in models) |
| Electricity Required | Yes | No | Yes |
| Wastewater | Yes (RO reject water) | No | Yes (RO reject water) |
| Maintenance Cost | Low to Moderate (Readily available parts) | Low (No membrane to replace) | Moderate to High |
| Key Strength | Powerful purification for the toughest water, Excellent value | Zero waste, works without electricity, Retains natural minerals | Multi-stage purification, Brand recognition |
| Key Consideration | Requires electricity, produces wastewater | Does not remove dissolved salts (TDS) | Higher initial & running cost, requires electricity |
Deep Dive into the Technologies
1. Deng Yuan: The Powerhouse for High TDS
Deng Yuan specializes in Reverse Osmosis (RO) technology, which is highly effective for many parts of Dhaka.
- How it works: RO forces water through a fine membrane, removing up to 99% of dissolved impurities like salts, heavy metals, and chemicals.
- Ideal For: Homes where the water has a salty or brackish taste, or where TDS levels are measured above 500 ppm. If your primary concern is removing dissolved solids and heavy metals, Deng Yuan’s focused RO technology is a powerful and cost-effective solution.
2. Ecosoft: The Eco-Friendly Guardian for Municipal Water
Ecosoft takes a sophisticated physical filtration approach, primarily using UltraFiltration (UF).
- How it works: UF uses a hollow fiber membrane to block all bacteria, viruses, and cysts, much like a microscopic net. It does not require electricity and does not produce any wastewater.
- Ideal For: Homes that receive treated but potentially bacterially unsafe water from Dhaka WASA, where the TDS is already at a safe, moderate level. Its ability to operate without electricity makes it a reliable choice during load-shedding and an excellent eco-friendly option.
3. Kent: The Multi-Stage Purifier
Kent is well-known for its combination of RO, UV, and UF technologies.
- How it works: This multi-stage process aims to cover all bases: RO removes dissolved solids, UV kills microorganisms, and UF provides a final safety barrier.
- Consideration: While this sounds comprehensive, it also means the system requires electricity, produces wastewater, and often comes with a higher price tag for both the initial purchase and long-term maintenance (replacing multiple filter types and UV lamps).
The Verdict: Which One is Right for YOUR Home?
The best purifier depends entirely on your water quality and household needs.
You should choose DENG YUAN if:
- A water test confirms you have high TDS (above 500 ppm).
- Your primary concern is removing dissolved salts, heavy metals, and arsenic.
- You are looking for powerful RO purification that offers excellent value and low maintenance costs.
You should choose ECOSOFT if:
- Your water has moderate or low TDS but you are concerned about bacteria, viruses, and sediment.
- You want to save on electricity bills and conserve water (zero wastewater).
- You need a purifier that works reliably during power outages.
- You prefer a system that retains beneficial natural minerals without the need for a separate mineralizer.
