Best Gravity based Water Purifier in India in 2019

There are two riddles we Indians face when it comes to safe drinking water.

  1. Unsafe Municipal water: Even if you have access to Municipal water, most of the times the water is affected by chemicals and microorganisms like bacteria and virus. You have no other option than to buy a high-quality water purifier
  2. Intermittent Power: Power failure is another problem we Indians face every day. If you use electric purifiers, you won’t have access to safe water during a power failure.

If you fall into this group, you have come to the right place. Let me tell you that you should read this article before doing anything today.

We have reviewed the best gravity based purifiers for your home here. Remember, they work best for low TDS of less than 300 ppm.

Water is essential to flush all the toxins from your system. But, is it always 100% Safe? We don’t think so. Here are the reasons why we don’t get safe and healthy Municipal water supply:

    • Improper water management
    • Bad environment conditions

Gravity water purifiers are the perfect choice for people who face scarcity of safe drinking water or electricity. They process and give drinking water which is safer than chemically affected Municipal Water and boiled water.

Moreover, the ample storage space ensures a continuous supply of water even when there is no running water supply.

Gravity Water Purifier Buying Guide

We are not leaving you with just those reviews.

Remember, a water purifier is one of the most important appliances in your home. It’s not a gadget, it’s going to define and decide your health in the coming years.

So, you should have a strong understanding of what you need (and don’t need) while buying a gravity-based water purifier.

Here is our buying guide to help you out in choosing the right gravity-based water purifier:

What Kind of Water can it filter?

This is the most important thing to notice before buying a gravity-based water purifier from the market. You can use this water purifier in the following scenarios:

  • For soft Municipal water not containing viruses and heavy metals.
  • For TDS less than 300 ppm

If you have a well or borewell water, buying a purifier that filters only MCD won’t work.

Family Size and the Capacity of Purifier

gravity water purifier reviewsBuying a small gravity water purifier to feed the daily water needs of a family of 4-5 people would be a foolish idea. At least one of them will have to sacrifice their needs.

Why would you go through so much trouble when you can buy purifiers like Tata Swatch and RAMA for bigger family needs? Hence, it’s necessary to have a rough idea about your family’s average water consumption per day before finalizing a product.

What is Your Water Source?

As I said before gravity water purifiers might not work well for well and borewell water.

If your ground level or borewell water source has higher TDS, then you need to buy a gravity based water purifier with the capacity of handling at least 250-300 TDS.

It’s a good practice to check the TDS level of the water before buying the purifier.

Which Kind Of Bacteria Does Gravity Water Filters Kill?

Check whether the gravity-based water purifier kills any bacteria, viruses, cysts or not. If the source of water at your home, office, or rented-house is prone to bacteria, then buy Tata Swatch or Kent Gold.

Is It Under Your Budget?

The budget won’t be an issue when it comes to gravity water filters. Majority of the gravity water purifiers are ranging from Rs 1500 to Rs 5000.

But you don’t have to always invest at the higher end.

Why? The price depends on the following factors:

    • The capacity of the Purifier
    • Additional features
    • Warranty

Supposedly, if you are living alone as a student, spending Rs. 3000-5000 on a water purifier might sound really odd. In such case, Rs. 1500-2000 would be enough—matching your daily needs.

The bottom line is that you should always have an understanding of your requirement before heading to the online store or market.
