Purifiers remove contaminants from water, making it more reliable for consumers to drink. Water purifiers can also destroy biological contaminants and remove certain minerals from the water. They take up polluted raw water, filter out contaminants such as sediments and microorganisms, and then deliver clean water. Different water purifiers have different functions in them and therefore the water purifier price in Bangladesh varies.
Viruses and microorganisms that filtration cannot eliminate can be removed by a purifier. To eliminate or catch viruses, some purifiers utilize chemicals, while others use an electrostatic charge.
The act of extracting unwanted chemicals, biological pollutants, suspended particles, and gases from tainted water is known as water purification. The idea is to create water that is suitable for a certain use. Although most water is sanitized for human utilization (drinking water), it can also be tailored for a variety of other objectives, such as meeting the needs of medicinal, pharmaceutical, chemical, and industrial applications.
Physical procedures like filtration, sedimentation and distillation are utilized; biological processes like slow sand filters or bioactive carbon are used; chemical processes like flocculation and chlorination are used, and electromagnetic radiation like ultraviolet light is used.

Buying guide for water purifier
Purchasing a water filter may appear to be a simple task, but it is not. The following variables will assist the consumer in determining which type of water purification system to purchase:
· Quality of water - If your home's water supply has high levels of Total Dissolved Solids (TDS), hardness, or salinity, RO (reverse osmosis) is the best option. RO uses a semi-permeable membrane that can filter out even the smallest amounts of dissolved salt, metals, and contaminants. Activated carbon filters can also be effective in other situations.
The most likely health-harming pollutants in water include bacteria, nitrates, dissolved pesticides, and lead. Any laboratory can test the amount of pollutants present in water.
So, if the water in your home is heavy in microorganisms and pollutants, UV-based RO filtering may be the best option. The UV impact irradiates the water and penetrates bacterium and virus cells, preventing them from reproducing. These organisms are unable to reproduce and will eventually die. The RO membrane cleans the water off these dead microorganisms and pollutants, making it safe to drink.
· Water pressure – You must check if your home’s plumbing system has sufficient pressure while pumping water. Both UV and RO filters require a high-pressure water source. The RO filtration will not function properly if the receiving water flow has insufficient pressure. Water pressure is affected by the height of your building as well as other factors such as clogged filters and blocked pipes.
· Purification system based on contamination levels –
-Water with high levels of TDS (500-2000 PPM) is treated by reverse osmosis purifiers (or RO purifiers).
-If your water consists of bacteria, viruses, or microorganisms that cause water-borne ailments, UV purifiers are used.
-Universal Purifiers integrate many technologies such as reverse osmosis, ultraviolet, and activated carbon to produce 100 percent pure water.
-Gravity-based water purifiers clean water by gravity and are suitable for water with low TDS. Unlike RO and UV purifiers, they do not need energy.
· Electricity - When it comes to water purifiers, electricity is crucial. Many cannot function without electricity, making them ideal for houses with severe power outages. When there is no electricity, an ultraviolet (UV) filter will not work since it relies on energy to produce ultraviolet light that kills microorganisms. An RO system will not function without electricity because it relies on it to supply sufficient water pressure to the RO membrane. Activated carbon purifiers, like sediment filters and ultra-filters, do not require energy (UF). Non-electric purifiers can only remove some of the compounds dissolved in water, as well as germs and sand, whereas RO and UV systems can remove TDS and microorganisms that cause waterborne diseases. Water purifiers which run on electricity are the best option.
· Availability of parts - Brands will occasionally state that a water purifier product has been retired from their catalog and that replacement parts are no longer accessible. In such circumstances, you must either use inferior parts or buy a brand new water purifier. As a result, you should choose for a different model from any manufacturer and inquire as to how long that model will be supported for replacement parts.
Conclusion
Although water contains numerous minerals that are beneficial to the human body, ingesting too much of it can lead to a variety of ailments. An excellent water purifier removes excess salts, suspended particles, and bacteria while preserving critical vitamins and minerals in the water. With so many companies in the water purification market these days, it's tough to know which ones are good, which aren't, and which fulfill the minimum requirements. Also, another important factor that you have to consider is the water purifier price in Bangladesh.
If you read over all of the features we've discussed and shortlisted water purifiers based on your requirements and the criteria we've listed in this buying guide, you'll have a good chance of finding the finest water purifier for your demands and budget.
