How to select Water Purifier for home

Rains give relief from the scorching heat, but it also brings along the threat of waterborne diseases from contaminated water. It is a serious concern that can cause diseases such as typhoid, cholera, diarrhea and many other gastrointestinal problems. Most of us still follow the traditional ways of boiling and filtering water at home, which consumes time and energy, while others find bottled water as an alternative.

This too can burn a hole in your pocket. A water purifier is the best, inexpensive solution for purifying water. It helps remove harmful impurities from the water and at the same time maintain a quality that is ideal for consumption. However, with so many brands and models of purifiers promising advanced purifying technologies, how do you go about buying a water purifier?

Is supplied water, safe and pure?

Most of us boil and filter water using a fine cloth or using traditional water filters. This is one of the easiest and effective ways to ensure pure drinking water. Some people prefer packaged drinking water but it is expensive. Are these methods really safe though? The only way to know if water is safe for drinking is by performing a water analysis test in a laboratory. Water is said to be pure based on the TDS (Total Dissolved Salt) and the pH levels. These values can be used to determine what kind of water purifier you need.

It’s ironical how the same monsoon that brings respite after a long season of sweltering summer is also responsible for one of the most disease-prone time of the year. The rains bring along one of the biggest problems of the season, water contamination. Drinking untreated water during this season can lead to several diseases and infections.

Equipping your home with a #NewAndNow water purifier will keep your family safe this monsoon. Soon the market will be filled with a variety of water purifiers, each specialising in certain technologies to beat various impurities. However, there is no “one type fits all” when it comes to water purifiers, so pick the one that best suits your needs. Here’s what you need to consider before picking a water purifier.

How to pick right water purifier

Water is an excellent solvent and has the tendency to dissolve most compounds. These include chemicals, metals, salts, minerals and a bunch of other impurities (total dissolved solids) it encounters at the source. Even though the water you receive through municipal supply goes through its own purification process, it gets contaminated during the transmission before it reaches your taps.

The pipelines that carry this water get worn out and give in to external pollution. In many cases, the sewage line is very close to the water pipes which further puts the water in a compromised situation. The monsoon worsens this condition. Considering the total dissolved solids (TDS) present in the water and the other impurities it accumulates on the way, the water you finally receive is laden with numerous layers of filth that lead to diseases and infections.

Types of water purifiers you need to consider

Water purifiers are available as two types – Electric and Non-electric. Electric water purifiers are useful in places with stable electricity supply, whereas non-electric purifiers are good for places with unstable electricity and erratic water supply. Purifiers are available with or without a storage tank ranging from 4 to 20 litres, and above. If you have a large family, choose one that comes with a storage tank if water supply is erratic. This ensures that you have access of pure water stored in a tank.

Different water filtration technologies


Reverse Osmosis (RO) technology

Water purifiers with RO technology are effective at removing invisible impurities. It also helps in reducing the hardness of water by removing harmful chemicals and the presence of lead, arsenic, mercury and chlorine in it. RO filtration technology is used for underground water sources or water that is supplied by water tankers. This method also works for distilling seawater and making it drinkable. Choosing a RO water purifier helps if the TDS (Total Dissolved Salt) is low in water test. Having an UV feature on your RO water purifier is also recommended for most locations.

RO Water purifier

Ultraviolet (UV) technology

UV water filtration technique is useful for soft water sources such as river water or rain water supplied by municipalities. This type of technology helps destroy microorganisms present in water, but is not effective in removing dissolved water chemicals. It would be best to choose UV water purifier if the presence of bacteria and microorganisms is high in water. If the water have a mix of solid impurities along with contaminants, consider buying a purifier with both, RO and UV filtration technologies. This is ideal for most of us.

UV Water purifier

Ultra-filtration (UF) technology

Mainly non-electric purifiers with storage tanks come with UF filtration technology. These type of purifiers are good at removing solids and impure particles present in water, but bad at removing dissolved impurities. It is good to go for a UF + UV filtration water purifiers if the water supply is known to have very low TDS ratings, which means water is safe for drinking.

UF Water Purifier

Activated carbon technology 

These type of water purifiers have two or more bar shaped sticks made up of charcoal granules. These sticks help absorb pesticides or chemicals present in water improving the taste of water. Purifiers with activated carbon technology work without electricity. This type of water purifiers can be considered in rural areas where you find mainly fresh water reservoirs.

Active carbon water purifier

As explained, an ideal way to filter impure water is to install a water purifier at your home. A majority of water purifiers use a combination of RO + UV +UF purification technologies and these are more expensive than single filtration ones. We would recommend using all three purification levels, since it is worth the investment when health is most important.

Storage Capacity

When buying a water purifier, it is very important to take into account the storage capacity. If you live in an area which is prone to power cuts, you need a water purifier which has a higher storage capacity. The automated water purifiers start the purification process as soon as the water level in the purifier declines.


Another important factor that you need to check in water purifier reviews is the certifications received by the brand. Certified water purifiers ensure that the brand is authentic and trustworthy. KENT has been honoured with some of the top quality certifications by NSF, WQA, ISI and CE.

Maintenance and After Sales Services

Lastly, before making the final decision, ensure that you get all the necessary information about maintenance and after-sales services of water purifiers. A water purifier that needs frequent maintenance services is not worth the money you invest. In addition, you also need to check the after sales services provided by the company. Poor after sales services lead to a lot of problems if something goes wrong with the water purifier.
