How to Buy the Best Water Purifiers in India 2021?

polluted sewage water with high TDS

Today, in India, the water pollution level is alarmingly high. Therefore, the need for a water purifier is an absolute must. Thus, in order to make your choosing process simple, we have covered most of the questions asked by the buyers in this detailed buying guide.

Some of them include which is the best water purifier in India? Which water purifier brand to choose? What does RO mean? Or what is TDS?

Apart from this, we will explain what factors to consider while buying a water purifier. Also, we will try you eliminate any confusion regarding which is the best water purifier in India.

Therefore, it is recommended reading this as the following information would prove very useful if you are buying a water purifier for the first time.

Type of Water Purifier

There are basically 3 types of water purifiers which are prevalent in the market. Each of these work of different purification processes. These are:

  • Gravity-based Water Purifiers
  • Reverse Osmosis (RO) Water Purifiers
  • Ultra Violet (UV) Chamber Water Purifiers
  • Ultra Filtration (UF) Water Purifiers

Gravity-based Water Purifiers

These are old school water purifiers where one container is placed over another. As the name suggests, these purifiers employ gravity for water purification. The impure water is poured manually to the upper container through the water filtering candles which contain fine holes.

From these candles, the filtered water then seeps through into the container below. As it works without electricity, this type of water purifier is a dated machine now.

This water purification system is an example of  the much advanced Ultra-Filtration (UF) Process.

Reverse Osmosis (RO) Water Purifiers

How RO water purifier works

Reverse Osmosis (RO) water purifiers are the most used water purifiers in India. As the name suggests, they work on the principle of Reverse Osmosis (RO).

For this first, we have to understand what osmosis is? Simply speaking, osmosis is the phenomenon in which water flows from a high concentration to a lower concentration through a semi-permeable membrane.

To better explain this consider this example. Suppose you place a potato inside a glass of water. Now, after some time you notice that the potato starts swelling up because the water from the glass (high concentration) seeps through inside the potato (lower concentration).

Here the potato skin acts as the membrane. The RO process is just the opposite of this.

In RO purifiers, the membrane has millions of minuscule pores of size about 0.0001 microns each. The water molecules are small enough and thus pass through the membrane ensuring the elimination of TDS.

As this method involves the application of pressure, RO water purifiers generally come with inbuilt pumps which quicken up the process.

Water with high TDS or with high impurities is pumped with pressure into the RO chamber. Due to this, water molecules from one side of the semi-permeable membrane are pushed to the other side which leavies the soluble solids and the other impurities behind.

The dissolved solids along with impurities are known as RO wastewater. It is then discharged through a separate outlet. Owing to their functionality, RO water purifiers are most suitable for purifying water which has a high TDS level.

Ultra Violet (UV) Chamber Water Purifiers

As the name suggests, Ultra Violet Water Purifiers use UV rays for the purification of water. UV purifiers come preinstalled with a UV bulb which produces high-intensity UV rays. Water is then made to pass through these UV rays in the UV chamber.

Any pathogen such as bacteria or virus coming in contact with these rays either dies or becomes inactive instantly. The UV purification process is successful in eliminating up to 99.99% of the available pathogens existing in the water.

However, one drawback of UV water purifiers is that they are unable to remove dissolved un-dissolved impurities such as chemicals from water. As a reason, most of the UV purifiers available in the market require external sediment pre-filters to remove undissolved impurities.

For example, the activated carbon filter removes Chlorine and other dissolved impurities.As a result, UV water purifiers are often recommended for areas where the TDS level of water source is low.

However, despite having a low TDS level if the water is contaminated with viruses and bacteria and appears muddy then you should go for a UV + UF water purifier.

Ultra Filtration (UF) Water Purifiers

Ultra-Filtration (UF) water purifiers work on the principle of Ultra-Filtration. Although the UF process is similar to the RO process, the UF Filters require semi-permeable membranes which have larger pores than the ones used in RO water purifiers.

This membrane contains several tiny pores which are the size of 0.01 microns each.Water molecules pass through the membrane with the help of these tiny pores.

However, germs and dirt particles are larger and thus cannot move through the holes. As a result, these impurities are then filtered out of water.

The main advantage of using UF purifiers is that they can operate without electricity. It is because of the membrane used. With much larger pores, water can easily pass through it naturally with the help of gravity.

This implies there is no need for external pressure or water pump. Also, another advantage of UF purifiers is that they do not retain any water. This simply means there is no wastage of water.

However, there is one downside. Due to the presence of larger pores, UF purifiers are capable of filtering undissolved solids and larger impurities only. This means that even though it can filter germs and dirt from water, it can’t remove dissolved chemicals such as lead, arsenic, pesticides, etc.

It is because these toxins can easily pass through these pores. Simply put, if your water supply has high TDS, then UF purifiers are not suitable for your use.

Things To Consider while buying, Best Water Purifiers in India

Total Dissolved Solids (TDS)

Cheking water quality with TDS meter

Total Dissolved Solids (TDS) is the measure of the amount of total dissolved solids present in 1 litre of water. It is measured in Parts per Million (PPM) or Milligrams per Litre (mg/l). Measuring the TDS value is very easy. There are several Digital TDS Meters available online which do this job perfectly.

Generally, the dissolved salts in water include sodium, potassium, magnesium and calcium. They are present as natural minerals. Once the TDS value of water is measured, the level of contamination of water and the purification process required can be easily determined.

According to the Bureau of Indian Standards (BIS), the maximum desirable TDS level for drinking water is 500 mg/L or 500 PPM and the maximum permissible TDS level when is no better source of water is 2000 mg/L or 2000 PPM.

It has been found that water which has a TDS level of less than 300 is considered excellent for human consumption. For TDS level between 300-500, it is considered acceptable. However, if the water has a high TDS level of 500-900, then it is not recommended for drinking purpose.

Water from industrial wastes has a TDS level of more than 900 and consuming it can lead to severe health problems.

In the table listed below, you will understand the relation between the level of water impurity and the type of water purifier required.

TDS ValueBacteriaMuddy Water Required Water Purifier
Below 300 PPM YES NO UV
Below 300 PPM YES YES UV + UF
Above 300 PPM NO NO RO + TDS Controller
Above 300 PPM YES YESRO+UV+UF+ TDS controller

NOTE: TDS alone is not a perfect indicator of water contamination. Individual Dissolved Substance is even better for determining the right amount of impurities present in water. For example, suppose a water sample has TDS value below 300 but it may contain a high amount of toxins like arsenic, lead or mercury. Thus it is recommended to go for a RO+UV+UF water purifier to avoid any confusion.

Quality of Water

Best water purifiers in India provide purified water

Water quality of your locality is the utmost important factor while choosing the best water purifier in India. Broadly explained there are 4 major sources of drinking water in India. These are:

  • Borewell/Groundwater
  • Municipal Corporation Supply
  • Lake/Ponds
  • Rivers

Water from these sources contains several different types of impurities and it thus requires different types of purification. This is summarised in the following table:

Water SourceImpurities Present
Visible impurities: mud, sand, etc.

Invisible impurities:
Dissolved Salts like Calcium, Magnesium, etc.

Harmful heavy metals and chemical impurities: Lead, Arsenic, Fluoride, Mercury, etc.
Municipal Corporation Supply
Visible impurities: mud, sand, rust, etc.

Invisible impurities: Bacteria & Viruses, Chlorine, etc.
Visible impurities: mud, sand, algae, etc.

Invisible impurities: Very high level of Bacteria & Viruses, Protozoa, Cysts, etc.
RiversVisible impurities: mud, sand, etc.

Invisible impurities:
Dissolved Salts like Calcium, Magnesium, etc.

Harmful heavy metals and chemical impurities: Lead, Arsenic, Fluoride, Mercury, etc.

Generally speaking, water coming from a lake or river is often soft water. While underground water or water from Municipal Corporation Supply is hard water. Underground water contains a high amount of total dissolved solids (TDS). Now to make things clear, consider the following points:

  • If the water at your home is hard, that is when its TDS value is above 500mg/l, then you need a RO water purifier.
  • When the water supply at your home is soft, particularly, that is when the TDS value is less than 500mg/l, then there is no requirement for an RO water purifier. In this situation, a UV water purifier would be the best choice.
  • But if the water is highly contaminated and as a result, its TDS value is quite high, that is more than 500 PPM, then you should definitely consider a RO+UV water purifier.

Storage Capacity of Water Purifier

How much-purified water you need at a time decides the storage capacity of the water purifier you choose. This factor becomes all the more important if your locality is facing frequent power cuts.

There, ideally, you would need a water purifier with a large storage capacity to ensure continuous purified water supply.

Water purifiers normally feature storage capacity which ranges from 7 Litres to 12 Litres. The bigger the family is, the more storage capacity would be required. Thus for a family with more than 6 members, an 8-10 Litre water purifier would be a perfect choice.

NOTE: Storage Capacity should not be confused from Purification Capacity. Purification capacity is the quantity of purified water which a water purifier can produce in an hour. This means a water purifier with a purification capacity of 12 Litres/hour can produce 12 Litres of purified water in an hour. Thus you must not ignore the water purification capacity while buying a water purifier.

Build Quality of Water Tank

While choosing a water purifier, you must consider the material or the build quality of the water tank. As a water purifier is essentially a safety device, and it is the tank where the water is stored, its composition and build quality also becomes important.

As a result, tanks of water purifiers from almost all best selling brands are composed of ABS food-grade plastic or stainless steel. These materials ensure water purity and tank durability.

Thus as a buyer, you have to keep one thing in mind; make sure to know the material beforehand. Also, another thing to note is that the water tank should be properly sealed to prevent any external contamination.

There is a simple general rule. Best water purifiers come with best quality internals. So, their somewhat extra price is justified.

Indicators and Notification Alerts

One of the often most overlooked features in water purifiers is the presence of indictors or notification alerts. The standard tank indicator shows the amount of water present in the tank.

Therefore, with its help, you can know whether the water storage tank is full or empty. Thus you can fill it as per your need. Similarly, the water purification on indicator will let you know whether the purification process is on or off.

Water purifiers also come with alarm systems or notification alerts. Just consider this situation. Suppose the UV lamp of the UV/UV+UF or RO+UV malfunctions, and the water purifier continues to dispense water.

Thus, in this case, in the absence of a UV fail alert/alarm, we wouldn’t have any other way to determine whether the UV lamp is functioning or not. Also, nowadays, another type of alerts are common in water purifiers. These are filter change alerts. These alerts help in notifying the user as to when the filters need to be changed.

Space for Installation

Installation space proves a key role in choosing the best water purifier for home. Generally, water purifiers can be installed in two ways: counter mounted or wall mounted. But if you don’t proper enough space on the counter or wall, there is another type of water purifier for you.

These are called under-sink water purifiers. As the name suggests, they can be installed below your sink, thus effectively saving you space as well as from a lot of trouble. For modular kitchens, under-sink models are often considered as the best water purifiers.

Price of Water Purifiers

Even though we have mentioned it this late, but the budget is often the most important factor in choosing the best water purifier in India. Their price depends on mainly 2 factors; their storage capacity and the water purification system.

Also, one more thing that should be considered here is the maintenance cost of the water purifiers. Coming back to pricing, Gravity based water purifiers are the cheapest as they start from as low as Rs 1500.

As for RO Water Purifiers, you can grab a good 6-8 stage machine starting from about Rs 5000-6000. However, if you are looking for a branded 7-8 Litre RO+UV+UF machine, then you can have that too at a starting price point of Rs 8000-10000 with their price going all the way up to Rs 15000- Rs 16000.

Warranty & After-Sales Service

Water Purifier is a device which is going to last you for years. Therefore, it would be smart on your part to choose the one which provides you with the best warranty. Generally, the best water purifiers come with 1-2 years of warranty.

So do your research before buying one. Apart from this they require regular maintenance, therefore choosing a brand which offers reputed after sales service would be the best bet for you.
