Every house needs a water purifier. It is one of the most important things to have just like having a Refrigerator or Gas at home. When you step out to buy a water purifier, you may be confused about which one to get to accomplish the mission of getting pure water free from dissolved salts, harmful chemical and harmful substances, etc.  Water purifiers can be many types but before spending money on one, we must know impurities or dissolved salts available in the raw water we are getting in our tap water. Our article will give you a clear picture of the types of water purifier and their working procedure.


ACTIVATED CARBON FILTERS: After the introduction of the benefits of multipurpose activated carbon, it has been used in industries, cosmetics, water purification, agriculture, and medical purpose. In water filters, they are generally used to filter organic compounds. They are well-efficient in providing chlorine-free water and can successfully eliminate the bad taste or foul smell from water. The technology uses carbon filters which are derived from the carbonaceous source of material and can remove pesticides from water. However, it cannot remove microbes, fluoride, sodium, and nitrate from water.

SEDIMENT CARTRIDGE FILTERS:  This technology uses sediment filters to remove sediments. Its main work is to remove the large solid particles like dirt, sludge, mud and other solid particles in water. The size of the pores in sediment is 20microns. The filters can get blocked but you can also clean them for reuse.

RO (REVERSE OSMOSIS) FILTERS: They are the most commonly used technology. The RO uses a membrane technology that can eliminate impurities, germs and dissolved salt from water. If your tap water contains is high in TDS (Total Dissolved Solids). The only loophole is it can also remove essential minerals from water.

GRAVITY BASED WATER PURIFIERS: They are non-electric water purifiers. They are efficient to remove bacteria, viruses and coarse particles like sand, dust, and dirt from water. They do need maintenance at regular intervals.

UV (ULTRAVIOLET) FILTERS: This is the latest technology used in today’s market. This is also termed as environmentally friendly as it doesn’t require chemicals or any additional heat. The ultraviolet radiation can successfully kill various bacteria and viruses which can cause health hazards.

INFRARED FILTERS: This is best used in areas having hard water supply as it can soften the water using infrared technology which uses light and heat to negatively charge the water.

Ultrafiltration: Ultrafiltration is a membrane filtration that is similar to Reverse Osmosis is commonly known as the RO water purifier. Ultrafiltration uses hydrostatic pressure to force water to pass through the semi-permeable membrane. The pore size is 103-106 Daltons. It is a pressure-driven barrier to suspended solids, viruses, bacteria and pathogens. It produces water with high purity and low slit density. It is best suited for municipal water supply and water with low TDS.
