Best Water Purifier- A complete buying guide

Water is an indispensable part of our life. Water regulates several bodies functioning and plays a vital role in replenishing the lost immunity.

With the rise of pollution levels, the necessity of water purifiers has increased.

Different Sources of Water

Earth is made up of 70% of water. Groundwater and surface water are the primary two sources of water on earth.

Surface water referred to those sources of water that are visible to our eyes. The water obtained from rivers, lakes, oceans, streams, and reservoirs.

Groundwater is referred to as the water available under the soil and between underground rocks. Out of 70% of the earth’s water, only 3% is consumable.

Kinds of contamination in drinking water

Primary water contamination is by industrial wastes being disposed untreated into water bodies. The contaminated water is treated with chlorine, and thus they smell so.

The various organic, inorganic, and even radioactive wastes are increasing every day with the rise of new industries.

What do you understand by TDS of water?

The total amount of dissolved solids found in water is called TDS (Total Dissolved Solid). The inorganic salts and small organic compounds fall into this category. Sodium, Calcium, potassium, and magnesium are natural nutrients.

An adequate amount of TDS is necessary for drinking water. Water might taste terrible if the amount of TDS is low. However, a higher TDS level means the presence of arsenic, fluorides in water.

The typical acceptable TDS values are:



Less than 300



Good- acceptable for consumption


Not good- not consumable


Poor- unfit for drinking

Above 1200

Unacceptable fatal

To measure the TDS level in the water, all you need is a TDS meter available at an affordable price in Amazon.

Point to remember: Please check the TDS level of every drinking water source. The TDS level of water supply from the municipality might be high or less than the water coming out of your tap.

What is the necessity to purify water?

According to the United Nations, around 100,000 Indians die annually because of water-borne diseases. That is a big wake up call for all of us, and thus we have to invest behind a trustable best water purifier.

The conventional water purification technologies

Presently, there are three water purification technologies involved in water purification, RO (Reverse Osmosis), UF (Ultra-Filtration), and UV (Ultra-Violet).

RO (reverse osmosis) purification

RO is the most advanced technology of cleaning available. Currently, RO is the only purification feature that can remove chemicals, bacteria, and even viruses.

With the advancement in technology, the pricing of RO purifiers has also dropped considerably. You can quickly get the RO based best water purifiers under 10000.

Processes involved in RO technologies:

There are four stages in RO purification, Pre-filter, Carbon-filter, RO filter, and Post Carbon filter.

Pre-Filter or Sediment Filter

The massive particle so dust, sand, or other visible dust particles are removed from the water through the Pre-Filter method. The amount of chlorine is also reduced from water at this stage.


The water coming from Pre-Filter passes through Carbon-filter. Organic compounds and foul odors get eliminated during this stage.

RO Filter

The water, coming out of Carbon-Filter, enters into the RO membrane. There are tiny holes on the plastic filter that allows only water molecule to pass through it. The dissolved substances like arsenic, fluorides, radium, barium, and other slow poison substances are eliminated at this stage.

Post Carbon Filter

The water finally enters into the post-carbon filter, where any remaining substances are eliminated, and the purest form of water is released for drinking.

In India, the top brands are Eureka Forbes, Kent, and Pureit.



It purifies hard water.

Works on electricity.

Disinfect water by killing viruses and bacteria.

Expensive than other purifiers.

UV (Ultra-Violet) water purification

UV method is used to kill germs present in the water. An ultraviolet bulb produces the UV rays. When germs and viruses pass through these rays, and then eventually succumb. The UV rays affect the genetic core of these microorganisms and thus kill them. UV is, therefore, the most effective way to prevent the spread of water-borne diseases.

UV also requires electricity to function just like RO, but it is a chemical-free process.



UV kills 99.9% of bacteria and viruses.

 It cannot remove dissolved substances.

Does not involve chemicals.

Cannot purify muddy water.

The maintenance expense is low.

Works with electricity.

Less expensive than RO purifiers.

Ultra-Filtration (UF) purification

It purifies muddy or dirty water, killing the harmful microorganisms present in it.

Process of UF purification

UF water purification technique uses a membrane just like the RO purification technique. The holes in the UF membrane are more significant than the RO membrane. When the water passes through the UF membrane, it allows only water molecules to pass while holds back the dirt and mud particles. But the UF membrane cannot eliminate the dissolved substances like pesticides, arsenic, fluorides, and many more.

If you are looking for the best non electric water purifiers, then purifiers with UF technology is what you must look for. UF technology is capable of purifying dirty muddy water as well as removes harmful microorganisms.



Works without electricity.

Cannot eliminate dissolved solids like lead, arsenic, and fluorides.

Purifies muddy water.

Least costly than others.
