Even though water is one the most vital element for human survival, it’s difficult to get pure water these days. With the increasing pollution, most of the drinking sources are contaminated with dust, pollutants, and even industrial chemicals. In the long term, these pollutants and microorganisms can do permanent damage to health.

So, before it’s too late, get yourself and your family, the best water purifier. But, afore you proceed, there are terms that you should be aware of, like Filtration methods, Purification capacity, Filter and Cartridge, Warranty, Storage Capacity, and Tank Type.

In this write-up, we have tried to clear every dilemma related to the water purifiers. During our research, we also came across a bunch of purifiers and listed the best of them here:

Purification technology

The purification technology used in water purifiers depends on the quality of water. For instance, if the water is too hard and contains a high level of TDS, RO (Reverse Osmosis) purification technology is the best. To be specific, if the TDS level is higher than 300ppm or the water is coming from multiple sources, nothing below RO works.

On the other hand, UV water purifiers are meant for treating water with a low TDS level and a high quantity of harmful microorganisms. To make the water free from any sort of contaminants, manufacturers have combined RO+UV+UF, UV+UF, and RO+UF. One good advice will be to check for the water quality at your home before you decide between RO and UV purifiers.

Filter and Cartridge

Look for water purifier with sediment filters as they are capable of removing dust, dirt and unwanted particles available in the water. The cartridge available in it should have activated carbon that removes bad odour and volatile components. Some additional benefits you can find here are Biotron Cartridge and a Mineral cartridge that offers essential minerals to the body while maintaining the PH.

Purification Capacity

It’s a simple attribute, but a necessary one so that you don’t have to switch on the purifier again and again. Opt for 12-15 litres of capacity for small and average family and more than 20 litres for large family size. While RO purifiers come with a storage tank, most of the UV purifiers lack it. Try to find a storage tank of 7-12 litres.

Indicators and Alerts

Most of the purifiers these days are offering fail alerts, which tells if there is time to change the filters or not. When the indicator reaches red, you should call the respective company for changing the filters.

Warranty and After-Sales Service

What if your RO come across a technical issue and there is no one you can reach. While customers don’t think of after-sales services as an important deciding factor, it should be taken into consideration for sure.  So, try looking for a service provider that gives a decent after-sales service.

Most of the brands give at least a year of warranty, so even that’s a factor you should look for. For example, Kent offers 1 year of warranty plus three years of free service, which is a good deal.
