Brand matters in Bangladesh because it decides the quality of the technology, how reliable the machine is, and how easy it is to get service and spare parts. In this guide we share real-world information based on our local experience. All prices mentioned are approximate street prices in Bangladesh as of February 2026 and may vary by shop, offer and location.
Why Choosing the Right Water Purifier Matters in Bangladesh
In Bangladesh, water sources are very different from place to place. Some common sources are WASA or city supply water, tube-well (deep and shallow), and surface water in rural areas.
City supply water often has lower TDS (Total Dissolved Solids) but can have bacteria, viruses, chlorine taste, and sometimes pipe contamination. Tube-well water can have high TDS, hardness, iron, arsenic, and sometimes a salty taste, especially in coastal or saline-prone areas. Rural surface water can be full of germs and dirt.
Unsafe water can cause diarrhea, typhoid, stomach infection, kidney problems, and long-term heavy metal toxicity from arsenic and other metals. So the right water purifier is not just a luxury; it is a health need.
The most important point is this: the right purifier technology must match your actual water quality. It should never be chosen only by price or brand name. A simple water test (TDS, iron, arsenic, bacteria) will guide you to the correct type of purifier.
Types of Water Purifier Technologies Used in Bangladesh
Understanding the basic technologies will help you choose better and avoid wasting money.
RO (Reverse Osmosis) Purifiers
RO purifiers push water through a special membrane with very tiny holes. This membrane removes dissolved salts and many harmful substances.
In Bangladesh, RO is recommended when:
- Your water has high TDS (usually above 300–400 ppm).
- You use tube-well water with iron, hardness, or arsenic.
- You live in saline-prone or coastal areas where water tastes salty.
RO can remove dissolved salts, heavy metals, arsenic, fluoride, many chemicals, and also improve bad taste and odor when combined with pre-filters and carbon filters.
The main benefits of RO are strong purification for dissolved solids and better taste. The main drawbacks are that RO wastes some water, has higher running cost (filters and electricity), and can reduce some natural minerals in the water. For many high-TDS areas in Bangladesh, this trade-off is still worth it for safety.
UV (Ultraviolet) Purifiers
UV purifiers use a UV lamp inside a steel or plastic chamber. Water passes around the lamp, and the UV light kills bacteria and viruses.
In Bangladesh, UV is recommended when:
- You use WASA or city supply water with low to medium TDS.
- Main risk is germs from old pipes or occasional contamination.
- You do not need to remove high dissolved salts or arsenic.
UV purifiers kill germs but do not change the TDS, hardness, or dissolved metals. So your water keeps its natural minerals. They also have low running cost because there is no RO membrane and less waste water.
But UV alone does not remove dissolved salts, heavy metals, or many chemicals. That is why UV is usually combined with sediment filters and carbon filters for better quality.
UF / MF and RO+UV / RO+UV+UF Combos
UF (Ultrafiltration) and MF (Microfiltration) are membrane stages that remove suspended particles, some bacteria and cysts, but not dissolved salts. They are often used with other stages.
Most multi-stage purifiers in Bangladesh use a combination like:
- Sediment filter to remove sand, rust and dirt.
- Carbon filter to remove chlorine, bad taste and odor.
- UF or MF to catch fine particles and some germs.
- UV for disinfection.
- RO for dissolved salts and heavy metals.
For WASA water in big cities, a UV or UV+UF purifier is often enough if TDS is low and there is no arsenic problem. It keeps minerals and has lower running cost.
For tube-well water with iron and arsenic, an RO-based purifier with good pre-filtration (iron removal where needed) is usually better. Sometimes we also suggest extra treatment if arsenic or iron is very high.
For offices, small factories and commercial use, larger RO systems or RO+UV dispensers are common, depending on water quality and daily consumption.
Tip: always test TDS and basic parameters before deciding. If you want help, we can test your water (or guide you where to test) and then recommend the right system from our Water Purifiers service.
How We Evaluated the Top 10 Water Purifier Brands in Bangladesh
When we made this list of the top 10 water purifier brands in Bangladesh, we used clear and practical criteria.
We first checked how common and available each brand is in Bangladesh, both online and in retail shops. A brand that you can easily buy and service is more useful than a rare brand.
We then looked at the technologies they use. We preferred brands that use proven RO, UV, UF and multi-stage filtration with proper design, not just cheap filters.
We gave high value to after-sales service. This includes the number of service centers, how easy it is to get spare parts and filters, and how fast problems are solved.
We also considered quality certifications where available (such as ISO, NSF, WQA or similar) and how strong the company’s quality control appears.
Real user feedback is very important. We listened to what customers say about reliability, taste of water, noise, and yearly maintenance cost.
Finally, we compared price range and value for money in the Bangladeshi market.
The ranking in this guide is approximate. The “best” brand for you may change based on if you need a purifier for home or office, for RO or UV, and if your budget is low, medium or premium.

How to Choose the Best Water Purifier Brand and Model for Your Home
Step 1: Test Your Water
First, you should know what is in your water. At minimum, check TDS (Total Dissolved Solids). If possible, also test iron, arsenic, hardness and microbial contamination.
Tube-well water often has high TDS, iron, and sometimes arsenic. City supply water usually has lower TDS but can have germs from old pipelines.
You can use a handheld TDS meter for a basic idea, but for serious issues like arsenic and bacteria, a proper lab or professional test is better. We can help arrange water testing or do an on-site check and then explain the report in simple language. You can contact us through our Water Purifiers service page for this.
Step 2: Match Technology to Your Water Type
Once you know your water quality, you can match it to the right technology.
If TDS is low (often under 300 ppm) and you use WASA or treated city supply, a UV or UV+UF purifier is usually enough. It will kill germs and keep natural minerals.
If TDS is medium (around 300–600 ppm), and you also worry about germs, an RO+UV or RO+UF system is a safer choice. The exact combination depends on your contamination levels.
If TDS is very high or your area is known for arsenic, you should use a good RO system with proper pre-filters. In some cases, extra treatment for arsenic or iron may be needed. In such cases, you should not depend only on basic domestic filters; take expert advice.
Step 3: Consider Family Size, Usage and Space
Next, think about how much water your family uses and how much space you have.
For a small family of 2–3 people, a purifier with 5–7 litres storage may be enough. For 4–6 members, an 8–12 litre tank is usually better. If you also want water for cooking, guests or small office use, consider larger capacity.
Check where you will install the purifier. Some models are wall-mounted, while others sit on the counter. In small kitchens, compact or wall units are better. RO systems make some noise when running, so consider if it will disturb you if placed very close to a bedroom.
Also think about power cuts. A storage tank helps during load shedding, but RO still needs electricity to run. If your area has many power cuts, we can guide you on models that suit that condition.
Step 4: Budget and Running Cost
You should look at both the purchase price and the yearly running cost.
Basic UV or UF purifiers cost less to buy and maintain. RO systems cost more because you have to change both filters and the RO membrane after some time, and they also use more electricity.
As a rough idea, a typical home RO system in Bangladesh may need about ৳2,000–৳5,000 per year for filters and servicing, depending on water quality and usage. Premium brands may cost more. UV lamps usually need replacement every year or two.
We always recommend planning your total 3–5 year cost, not just the first purchase price. If you want, we can estimate yearly maintenance cost for any model you are considering.
Step 5: Service Network and Warranty
Service is very important for any water purifier.
Before you choose a brand, check if it has a service center or trusted dealer in your city or town. Ask about response time, filter prices, and warranty terms.
A cheaper purifier with poor service can become more expensive in the long run because of breakdowns and unsafe water. Branded or properly supported systems are safer for your family and your pocket.
If you are unsure which brand suits your home and area, you can contact our team for a quick assessment. We supply, install and service multiple brands and can give you an honest comparison.
Water Purifier Price in Bangladesh: What to Expect
Water purifier price in Bangladesh depends on many things: technology, storage capacity, design and brand level (budget or premium).
In general, basic UV or UF purifiers for city water usually cost around ৳5,000–৳12,000. These are good if your TDS is low and main risk is germs.
- Entry-level RO purifiers typically start from about ৳8,000–৳18,000. These are common for tube-well water with medium to high TDS.
- Mid-range RO+UV+UF systems, which many families prefer for mixed water sources, are often in the ৳18,000–৳35,000 range, depending on brand and features.
- High-capacity RO systems, hot and cold water dispensers, or office units can range from around ৳25,000 to ৳70,000 or more, based on capacity and extra features.
Yearly maintenance cost also changes by type. UV or UF units have lower yearly cost. RO units have higher cost because of membranes and extra filters. For most homes, planning roughly ৳2,000–৳6,000 per year for service and filters is a safe starting point, but we can give a more exact number once we know your water and usage.

FAQs – Water Purifier Brands & Prices in Bangladesh
Which is the best water purifier brand in Bangladesh right now?
There is no single “best” brand for everyone. Pureit, Kent, Deng Yuan, Heron, Aquaguard, Walton, Lan Shan, Aqua Pro, Sanaky and Midea are all strong choices in different price ranges. The best water purifier brand for you depends on your water quality, budget and local service support. We usually suggest 2–3 brands after we see your water test and location.
Which water purifier is best for WASA water in Dhaka or Chattogram?
For most WASA or city supply water with low to medium TDS, a UV or UV+UF purifier from a good brand is usually enough. It kills germs but keeps minerals. If your building has an old overhead tank or you suspect pipe rust, a multi-stage UV+UF system with good sediment and carbon filters is better. We can test your TDS and suggest specific models suited for Dhaka or Chattogram conditions.
Which is better for tube-well water: RO or UV?
For tube-well water, RO is usually better because tube-well water often has higher TDS, hardness, iron and sometimes arsenic. UV only kills germs; it does not remove dissolved salts or metals. In many tube-well areas, we recommend RO or RO+UV systems, sometimes with extra iron or arsenic treatment if levels are high.
What is the average price of a good RO water purifier in Bangladesh?
A decent home RO purifier in Bangladesh usually costs around ৳10,000–৳25,000, depending on brand, number of stages and storage capacity. Premium RO models from top brands can go above ৳30,000. We can guide you to options that give safe water without wasting your budget.
How often should I change RO filters and membrane?
Most pre-filters (sediment and carbon) should be changed every 6–12 months, depending on water quality and usage. The RO membrane often lasts 2–3 years in normal conditions, but in very high TDS or dirty water it may need replacement sooner. UV lamps usually need change every 1–2 years. It is best to follow the brand guideline and also watch for changes in taste or flow. We offer scheduled servicing so you do not have to remember all dates yourself.
Is RO water safe for children and elderly people?
Yes, RO water from a properly designed and maintained system is safe for children and elderly people. It removes many harmful impurities and heavy metals. Some mineral content is reduced, but a balanced diet usually covers mineral needs. If you are worried about low minerals, we can suggest RO systems with mineral cartridges or TDS control that keep some minerals in the water.
Are local brands like Walton good enough compared to imported brands?
Local brands like Walton can be a good choice, especially because of easier service and spare parts. The important thing is not only where the brand comes from but also the design quality, filters and after-sales support. For many Bangladeshi families, a well-designed local brand with strong service is better than a cheaper imported unit with no support.
Can I run a water purifier without testing my water first?
You can, but it is not wise. Without a basic water test, you may choose the wrong type of purifier. For example, using only UV on high TDS or arsenic water is risky. Or using RO where TDS is already low can be a waste of money and water. We always recommend at least a simple TDS test before deciding, and we can help you with a more complete test if needed.
Do I need a water purifier if I already boil my water?
Boiling kills many germs but does not remove dissolved salts, heavy metals, arsenic, harmful chemicals, or many impurities that affect taste and long-term health. In many areas of Bangladesh, especially with tube-well or polluted sources, a proper purifier is safer than only boiling. Some families use both: purifier for daily use and extra boiling for babies or special needs.
How do I know if the purifier installation was done correctly?
A correct installation should have no leaks, good water flow, and proper flushing of new filters. RO waste water should drain smoothly. The taste of water should be clean, without strong chemical or plastic smell after initial flushing. If you see frequent leakage, very low flow, or strange noises, installation may not be perfect. Our technicians follow a clear checklist during installation and will explain to you how to notice any issues early.
Final Thoughts
Choosing the best water purifier brand and model in Bangladesh is not about picking the most famous name or the cheapest price. It is about matching the right technology to your water quality, checking real service support in your area, and planning for running costs.
Your next steps can be simple. First, test your water or at least check the TDS. Second, shortlist a few brands and models using this guide, based on your water type and budget. Third, talk to a professional water treatment team before you buy.
