Best Water Purifier buying guide

Water is an inevitable element for life. One can even survive without food, clothes or other necessities but not water. Water is present all around the globe in a substantial quantity. About 71% of the earth surface has water, but you can’t drink it as it is. Even with sufficient amount of water, there are a lot of natural and made conditions which make it unhealthy to consume.

Impure water and its causes

Water consists of a high amount of TDS “totally dissolved solids” (we will discuss it deeply below). Presence of salts like potassium, chlorine, magnesium, phosphate makes if totally unhealthy even hazardous for health. Along with this human factor like sewage, harmful factory waste, disposal of medical and house garbage in water leads to generate several impurities making it extremely dangerous. Additionally, a municipal corporation in town adds chlorine to disinfect water which is equally unhealthy for consumption.

Similarly, groundwater which we get thorough wells consists of salts and minerals. This proportion of salt increases more towards the underground in the coastal area. Other impurities like animal and plants matter are possibly present in groundwater, making it impure.

The need for water purification

All the natural or human-made impurities makes water infected which leads to several diseases. Like dysentery, arsenic (caused due to poisonous substances released from factories), typhoid, cholera, diarrhoea, and several poisonous and hazardous ones. Such diseases may become life-threatening also. Therefore, there’s an urgent need to purify water before used for drinking and cooking purposes.

People in different regions of the country use ordinary filters to get clean water. Filters only separate the mud from water but do not do anything in removing any of the harmful substances. That is the reason its fundamental to have a water purifier with advanced technologies and features that can remove all the impurities making your water fresh and pure to consume. Now for removing all these impurities, it requires modern technologies like RO (Reverse osmosis), UV (ultraviolet) purification and UF (ultra-filtration). All the models we have mentioned in the Best water purifiers for home in India list consist of each of the essential features.

Important factors to keep in mind before buying a water purifier for your home

  • TDS test – It is imperative to perform a TDS test to determine the number of TDS present on the water supply of your area.
  • Storage capacity – Ensure the storage tank capacity of the water purifier is up to your family needs. Families with 3-4 people can opt for 7 litres, 5-6 people can opt for 8 or 9 litres and families with more members must opt for higher storage capacity.
  • Purification capacity- The purification capacity of a water purifier is an essential factor to get looked after. Purification capacity is the number of litres a purifier can filter in an hour. All the models mentioned in our best water purifier in India 2020 list comes with the capacity of 12ltr/hour, 15ltr/hour and even 20 litre/hour. Make sure you choose the one according to your daily purified water requirement.
  • Tank type – The water purifier tanks get either made up of general plastic, food-grade ABS plastic or stainless steel. Make sure to choose the one with food-grade ABS plastic tank or stainless-steel tanks. Also, many purifiers come with a tank protection cover to keep it secured from outside dirt and dust.
  • Certification – Always opt for the appliance that is reputed and certified for the technology and features they use. Many leading brands have their water purifiers quality tested and approved under the reputed test.
  • After-sales service and warranty – It is essential to opt for water purifiers from brands that provide excellent after-sales services. Generally, the minimum guarantee for the product comes off one year, but certain brands like Kent give an extended warranty and free after-sales service for three years from purchase.
  • Space – Go for the water purifier that can suitably be placed on your counter-top or mounted on the wall. Make sure you do not buy a big sized one that does not get fit on your kitchen space.
  • Budget and maintenance – There are numerous water purifiers available in the market starting from 8000 to 25000. You must opt for the one that suits your budget. Also, study about the maintenance factor that includes the replacement of filters and any cartilage.

A brief explanation for water purification terms and technologies

TDS – The term TDS referred to as “totally dissolved solids”. Its major components come from chlorine, potassium, magnesium, sodium, nitrates and more such elements. TDS is somehow present in all the water resources found around us. Underground water or other sources have TDS level below 900. It also consists of some of the salts and mineral that our body requires. Here it becomes essential and tricky to eliminate the higher TDS level and maintained the required to a certain extent that is acceptable for consumption.

Now the main question that exists here is how much TDS is acceptable for human consumption. We have prepared a table below for the same. Please take reference from the table:

Source: Quora.com

The high level shows you the amount of TDS human body can accept. As we mentioned above, underground water and other water resources consist of TDS below 900. In the table we can see TDS up to 900 is marked fair for drinking. But it is not said fine to consume such water directly without filtration. Also, even if water from any natural source consists of TDS below 300, still it may include some of the other impurities in many forms.

Now in this condition, one needs to purify water with a reliable appliance before consuming it. This water purification requires technologies and features that are fit to clean contaminated water yet can balance the essential minerals, salts and taste of it. Let’s now discuss these technologies:

  • Mineral RO technology: Within this technology, the purifier performs a multistage filtration by using high pressure to pass water through a semi-permeable membrane to push out the microorganisms and minerals. Though the RO technology also removes essential minerals from water which are suitable for human consumption.
  • Mineral booster: With the mineral booster technology the purifier retains the essential minerals (calcium and magnesium) that were removed during the RO purification process and balance out the pH level of water yet improving its taste.
  • MTDS technology: The MTDS technology present in water purifier ensures that the purification works for various sources of water can control TDS up to 2000 milligrams/litres.
  • UV disinfection technology: Within this technology, the UV (ultraviolet light) destroy the microorganism, which leads them to grow further. UV penetrates pathogens in water and damage the DNA of organisms like bacteria, moulds, algae and viruses.

Types of filters and cartridge used during the purification process

During the purification, process water passes through several screens. Each filter works in enhancing the quality and purity of water.

  • Sediment filter: This filter usually acts as the first one to response the water impurities. It acts as a sieve to remove suspended particles and large contaminants and reduce sediments. This filter gets usually placed outside the purifier in the form of a cartridge.
  • Activated carbon filter: The activated carbon filter removes toxic organic compounds like pesticides and heavy metals from water. It also eliminates the smell and bad odour, leaving water feel fresh for use.
  • RO membrane: The RO membrane removes or separates the dissolved impurities in water under high pressure through a semi-permeable membrane.
  • Silver Impregnated Taste Enhancer: Usually present at the last or second last of filtration process this silver-impregnated taste enhancer removes VOC and organic residue while improving the taste and texture of water.
  • Revitalizer Cartridge: Again, present at one of the last stages of filtration this improves the hydration capacity of water so that its minerals can be absorbed in a better way by our body.
  • Biotron Cartridge: It breaks down the molecules of water so that you can enjoy the goodness and nutrients of waterway more quickly.

Purification technology

All the water purifiers you will come across in the market will have purification technology RO/UV/UF. RO treats hard water with high TDS, whereas UV treats water with microorganism responsible for high-level diseases. UF treats particulates and macromolecules from raw water to make it portable. Several purifiers use RO+UV in a combination to clean water with high TDS and microorganism. Also, some multistage water purifiers use RO+UV+UF in conjunction to treat water from several sources.
