Water is a basic requirement for every living organism. Therefore, good water purifiers are essential as well. Non purified water can be quite dangerous to health and can be the source of many fatal diseases. Therefore, investing in good water purifiers can ensure that the water is fully safe to consume. In this buying guide, the types of water purifiers and some important factors to consider are listed below.
What are the different types of water purifiers?
The best water purifiers are classified into five major types based on their working mechanism, and they are:
The RO water purifier basically uses a semipermeable membrane to purify the drinking water. It mostly runs on an electric supply. The raw hard water is passed through the RO membrane. The dissolved solid materials like arsenic, fluoride, lead, chlorine, and many other harmful ingredients are confined in the membrane, and the water is purified. The RO water purifier also enhances the water's taste by getting rid of any contaminants from the water that may be the reason for the odor.
The UV water purifiers are an excellent option to kill any microorganisms, pathogens like bacteria, viruses, and so on that can be the reason for any fatal diseases. It basically uses a UV lamp tube through which the water is passed for purification. The water is exposed to UV light, which removes all the unwanted particles and pathogens. The UV water purifiers are the best choice for low TDS (total dissolved salts) water such as lakes, rivers, etc. These are not meant for treating the hard water and therefore cannot eliminate chemicals like arsenic, chlorine, etc.
The UF water filter basically uses hollow fibers of a specific type of membrane for the purification purpose. The membrane is made of a thin layered material that can easily separate the water from various other particles. When the water is passed through this specific UF membrane, the solids, bacteria, viruses, and others are retained in the membrane itself. It is great for trapping the larger particles from the water. The UF water purifiers are the best choice for places where chemical contamination is relatively low in general.
The water purifiers' basic mechanism is that the water moves from a higher chamber to the lower chamber and therefore purifies due to the pressure levels. The gravity-based water purifiers are not the best choice for filtering out the microorganism and any heavy metals.
This type of water purifier requires the usage of activated carbon. The activated carbon is basically made of coal, nutshells, wood, coconut shells, charcoal, etc. These water purifiers can easily eliminate any water-borne diseases causing pesticides from the water and heavy metals. These are quite popular due to their ability to remove chlorine from the water effectively. Basically, during the purification process here, the chemicals and metals present inside the water get stuck to these water purifiers' activated carbon surface. As a result, the clear water flows into the lower storage tank.
Here the sediments filters are made from cotton, polyester, and other such fibers. They basically appear in a cylindrical shape and are plastic sealed. When the water is passed through the sediment-water purifiers, the sediment filter captures all the dirt, dust particles, and other visible impurities. One needs to make frequent replacements of the sediment filters/candles since these get expired very quickly.
The best brand of water purifiers like Kent, Aquaguard, Havells, and so on have an intake capacity of approximately 7 liters or even more, which can be chosen depending on the family members.
The tank of these hot and cold water purifiers is usually stainless steel, food-grade plastic, or any metal alloy. It is safe to filter out the water without any exterior reaction that can cause harm to the body.
Many electric water purifiers automatically shut off when there is ample purified water present in the lower storage tank. This eliminates wastage of extra electricity.
Most of these water purifiers have an LED display panel that displays the purified water's status and various other aspects conveniently.
These electric water purifiers have various water flow rates varying from 600 ml per minute or even more, suitable for quick water purification of water.
These water purifiers usually consume a power supply of approximately 200 watts to 800 watts, which is quite low. Therefore, there is no risk of extra electricity bills piling up every month.
These water purifiers are a basic necessity for every home and workspace and are not highly-priced by most brands. Most of the water purifier machines cost approximately ₹4000 to ₹15000, which is quite economical depending on the specifications.
Issued with the purification rate or the quality of the purified water, in general, can be easily fixed by the brands. Most water purifiers come with a warranty period of one year to four years for such unexpected scenarios.
Final Thoughts
Clean and pure water is essential. These water purifiers will ensure that every drop of water is devoid of harmful chemicals or microorganisms and are completely safe to consume. One can significantly reduce the risk of any water-borne diseases due to any heavy metals or such chemicals. Check out the list given above to know about the top 10 best water purifiers.
