Water Filter Price in Bangladesh | RO, UV, UF Purifier

Water Filter Buying in Bangladesh

Water used to be another name for life but now it has changed a bit. Pure water is another name for life. Because at present, along with various environmental pollution, water is also getting polluted gradually. Pure water is essential for human health. But getting pure water has become very rare now. This is because the water in most places today contains various contaminants such as lead, chlorine, and other harmful substances as well as various harmful viruses and bacteria that cause diseases which are extremely harmful to the human body. Many of us try to purify water in the traditional way but it is not always possible to remove all these harmful substances from the water by boiling. This requires a modern filtering system.

Budget for pure water

Most of the water filters used in homes in Bangladesh are ultra technology water filter. Generally, this type of purifier machine is primarily used for water purification. Ultra filtration technology water filter price starts at 3,000 Taka which can do general filtering using gravity based or electric pump based. Ultra technology water filter is popular in BD because of its low price. Some ultra filtration water filter includes ultraviolet for killing germs and their price is little higher. RO purifying system works very well for better purification of water. Water filter price in BD depends on the brand, model, water capacity, hot and cold water system, filtration system, filter stage and other features.

Filtration technology

Different brands of water filter with advanced technology and feature is available in Bangladesh market. However, water filter price in Bangladesh varies based on technology.

• Reverse Osmosis: It is a widely used process to purify water by purifying any harmful chemicals from water, microscopic particles and molecules, largest particles, microscopic microorganisms such as viruses and bacteria. In this method, the water is purified in several steps. It consists of a poly filter to purify the water, then a small poly filter to clean the small particles, then a carbon filter to clean the biochemicals, then a thin film membrane that can remove any germs or microorganisms, and finally a very small Carbon filter. In Bangladesh, WASA water is generally used for all purposes. In this case, water filter with reverse osmosis technology maintains the right quality of both the taste and smell of water, providing water suitable for young children and elderly people. RO water filter price in Bangladesh is around 3,500 Taka but the RO filter price mainly depends on number of filtering stage, membrane quality and additional filtering technology added for purity. Some RO filter comes with box design that means all filters are inside the box and the this RO filter price is little pricier like above 15,000 Taka. RO filter in Bangladesh is now most common filtering system and it is replacing the traditional purification system.
• Ultraviolet: This method can easily destroy organisms from water. For this, first, the microbiological growth of water is reduced then UV radiation with a wavelength of 254 nanometers destroys the DNA of the microorganisms and kills all kinds of bacteria, viruses, algae, and fungi in the water. Ultraviolet usually do not the only purification system. Additional PP cartridge and carbon filter are used along the ultraviolet so this system is little pricier like the lowest price of this water filter in Bangladesh is 5,000 Taka.
• Ultrafiltration: This method uses UF membranes to purify water which helps in controlling tolerant chlorine and water PS. In this method, chemicals are cleaned from the water. The price of ultrafiltration water filter in Bangladesh is almost same as ultraviolet purifier.
• Gravity-Based: Gravity-based water purification system is very simple process, that can be used without electricity. Gravity-based water filter mainly destroys viruses, bacteria, and other micro-organisms in water through sedimentation, and microfiltration process to deliver clean water. Also, it can easily remove chemicals that affect the taste and smell of water. Gravity based water filter price in Bangladesh is as low as 2,000 Taka and very popular to everyone for its affordable price. However, changing the filter regularly is very essential for this purification system.
• Water treatment plant: Some water purifier is sold based on the requirement such as how many liter of water is required per hour. This type of water purifier is specially designed for industries.

Water filter features

It is very important to consider suitable water filter for pure water supply in homes, offices, or industry. There are numerous water filters of different brand at affordable price in Bangladesh market. So besides considering the price, here are some important things to consider:

• Water Quality: Water filter is made up of various technologies such as reverse osmosis, ultraviolet, ultrafiltration, treatment plants, and gravity-based systems, which remove viruses, bacteria, and other harmful organisms from water and maintain water quality. So TDS level of water should be considered before buying water filter. Generally, water with 500 TDS level is considered clean and water with 1000 TDS level is considered as polluted water. So before buying a water filter, you must check the water quality of the specific area using a TDS meter.
• Filter Capacity: Water filter is one of the ways to supply pure water to homes, offices, or industrial plants. Therefore, before buying a water filter, it is necessary to consider one with the capacity to supply pure water according to the needs of the people in the place of use.
• Water Flow Rate: Water flow rate must be considered before buying a water filter. How fast a filter can purify water depends largely on the flow rate of the water filter. Therefore, consideration should be given to whether the water flow rate is appropriate according to the water demand.
• Micron Rating: Contaminated water contains viruses, bacteria, as many micro-organisms, which are harmful to the health of people of almost all ages, from children to the elderly. So before buying a water filter, you must check the micron rating of the water filter. A water filter with a low micron rating can quickly remove many of the smallest particles.
• Filter warranty and replacement system: Water filter internal filter should be checked for performance, duration of use, and ease of replacement. Therefore, before buying a water filter, you should consider durable and long-lasting filters, which will save costs.
• After-Sales Service: Warranty must be considered before buying a water filter. Because the water filter with a long warranty ensures long-lasting use without any trouble. Also, after buying the water filter should check the after-sales service for any defects.
• Other Feature: Digital display, smart water tank, and water filter with various features are commonly available in Bangladesh at affordable prices. So the water filter should be considered according to the requirement of smart features.
• Certification: Check for certification from a reputed organization like NSF International or Water Quality Association. This is because certification by these organizations basically guarantees that the water filter has been tested and is capable of meeting certain performance standards for removing contaminants.

Additional features

• Hot & Cold: Some water filter comes with hot and cold facility and some only cold facility. So choose the right one that suits your need. Hot and cold water filter price in BD is at least 15,000 Taka. However, before purchasing hot and cold water filter in Bangladesh make sure to learn more about their quality.
• Reservoir: Most water filter includes reservoir so choose the appropriate size for your family. Usually the 8 liter reservoir comes with electric water filter system.
• Filter replacement warning: This is a good feature and many modern electric filtering system includes this feature.

After buying water filter

• The filter cartridge needs to be changed periodically during the use of the water filter so that the proper filtration system is always maintained.
• Viruses, bacteria, and other impurities accumulate inside the water filter, which must be cleaned periodically.
• Also, dust and dirt should not accumulate on the outside of the water filter, so it should be kept clean with a soft sponge cloth. If necessary, clean the outside of the water filter using a mild detergent.
• In addition to regular use, the filter should be checked for any kind of leakage and should be repaired if necessary.
• As a result of continuous use for a long time, dirt, viruses, and bacteria can accumulate inside the water filter and cause infection. So it is better to sanitize the filter stages after a certain time.
• Water filters have specific containers to hold the water, in which the water collects after being filtered. To prevent the infection of viruses and bacteria, the container with water must be cleaned regularly and kept well covered.
• The TDS level of the water should be checked to verify that the water filter is properly removing the contaminants from the water.
• Check whether the water flow is correct by using water filter. If the water flow is slow, the filter should be cleaned. The filter cartridge must be changed if necessary.
• Additionally, each brand and model of water filter comes with its own manufacturer's manual maintenance guide. Therefore, in the case of water filter maintenance, follow the specific instructions as well as contact the service point of the brand if necessary.

Essential Question About Water Purifier

Can it filter salty water?

Yes, but it depends on the technology used in the filter. Reverse osmosis (RO) is a popular filter for purifying saline water.

Can it run without electricity?

Not all filters are required electricity such as simple water filter. But RO water purifier requires electricity and will stop filtering once the power cut off. However, most RO system has a reserved tank to store water and will continue supply the water using the tank pressure until the tank is empty. That's why this reserved tank sometimes called as pressure tank.

What is the pH after filtration?

The standard pH of water is 6-8. After filtration, the water pH will be 6-7 which is very safe. For some filtration technologies, you can make the water more alkaline using additional cartridge.

What will be the TDS after filtration?

500 mg/L is a safe TDS for any filtration technology. You need to check your water TDS using a TDS meter.
