How to choose best water purifier for home in India (Buying guide).

A water purifier is an essential appliance for your home & family health. The water supplied by municipal authorities may be contaminated due to its supply line running underground. Chances of leakage are very high.

You need to consider the following points before buying a water purifier online in India. We have created the below buying guide for you to help to pick the correct water purifier for your home & safeguard your family.

1. TDS of water.

The first & foremost important step is to check the TDS of water at your home. TDS is total dissolved salt in water & measured in ppm. The dissolved salt gives a taste to water.

These salts & minerals are essential to the human body. If consumed in the required quantity, it is suitable for health.

Due to water pollution, these salts & minerals, along with other contaminants, pollute water sources. It leads to an increased concentration of salts, minerals, metals & pollutants in the water supplied. This causes health issues & higher costs for medical treatment.

For this reason, it is crucial to know the water TDS level for your water supply.

You can quickly check TDS with digital TDS. Based on the TDS of water, you can choose the purification process required in your home.

Refer to the below table for TDS & water drinking quotient.

TDS Level in parts per million(ppm)Drinking Quotient
Below 50Not Good
Between 50-150Good
Above 500-1000Very poor.
Above 1000Unacceptable.
TDS Level & Drinking quotient.

2. Source of water supply.

The source of water supply also decides the choice of the purifier. It plays a vital role in the quality of water.

We received water mainly from the following sources.

  • Rivers.
  • Well / Borewells
  • Lakes.
  • Municipal corporation.

These water sources carry impurities as below.

RiverWaste material, mud, Industrial waste, human waste.
BorewellSand, dissolved salts, lead, etc.
LakeAlgae, plants, bacteria, waste, etc.
Municipal corp.Bacteria, mud, rust, etc.
Water Sources & impurities.

The municipal corp supplied water is treated for most impurities, but it is not always safe.
It has to pass several areas through pipes & the chances of contamination are higher due to rusted, leaking pipelines.
You must know your water supply source to select your water purifier.

3. Purification process.

We use 3 purification methods to filter water & make it drinkable.
They are UV (ULTRA VIOLATE), UF (ULTRA FILTRATION, RO (REVERSE OSMOSIS). The working of these three methods is different from each other & have their merits & demerits.
No single purification method is perfect due to different impurities in water. The choice of water filter depends on the contamination, TDS, source of water supply.
Based on the TDS of water & biological impurities, you can use the following type of water purifier.

MORE THAN 1000 PPMYESYESWater Softening Solutions.

Ultra-Violate (UV).

Water has bacteria & viruses, which can be killed by boiling water. However, this also alters taste & removes essential minerals from water.

In this method, water is passed through a UV lamp which operates at a 254 nm wavelength, and it kills bacteria & viruses present. This method ensure water is safe for consumption.

This method has a few limitations, and it does not remove dissolved salts & impurities from water.

If the TDS of your water is lower than 500 ppm, you may combine a UV purifier with a sediment prefilter to remove non-dissolved salts.

Advantage – 

  • Kills 99.99 % of bacteria & viruses.
  • No change in taste of water.

❌Disadvantage – 

  • Do not remove dissolved salts.
  • Need electricity to work.

Ultra-Filtration (UF).

The ultrafiltration works with semipermeable membrane. Water is passed through this membrane which has tiny pores of 0.01 micron.

Water can be passed through these pores quickly with the help of gravity but not suspended particles. There is no water discarded during the purification process. 

UF can remove suspended particles, pathogens, bacteria, solids, etc., but it cannot remove dissolved solids from water. It does not help to bring down the TDS of water.

UF filtration is suitable for water with TDS lower than 500 ppm.

Advantage –

  • No water wasted during filtration.
  • No electricity requires to operate.
  • Cost is cheaper in comparison with RO.

❌Disadvantage – 

  • Do not remove dissolved salts.

Reverse Osmosis (RO).

This purification method works with a semi-permeable membrane. The difference is its pore size. It has a smaller pore size of 0.0001 microns through which water molecules can be passed. 

With a smaller pore size, water pass with force through the membrane. It separates bacteria, suspended particles, minerals, etc. 

RO is best for water having TDS above 500 ppm.

Advantage –

  • Filters water with high TDS.
  • Remove all bacteria & dissolved salts effectively.
  • Low maintenance. 

❌Disadvantage – 

  • Remove essential minerals.
  • Cost is high in comparison to other purification methods.
  • Electricity is required for operation.

Now you know the difference between all the purification & you can choose as per your requirement.

4. Water Storage Capacity.

The purification process requires a certain time to process water. 

In many areas, power cuts are frequent where purifiers cannot be used continuously. 
All water purifier comes with a storage tank to void this problem. It ranges from 6 liters to 12 liters for a home water purifier.

For a family of 4-5 people, a water purifier with 7 liters of storage is suitable for daily consumption.

If your family is big & living in an area where power cuts are frequent & more prolonged, you can opt for a water purifier with a bigger storage tank. 

5. The flow rate of water.

The flow rate is the quantity of water is purified in an hour by a water purifier. It determines the capacity of a water purifier to provide clean & safe water.

A low flow rate will require a longer time for filtration & slow filling up the storage tank. In the case of a power cut, the tank will not be full. It may be time consuming & slightly frustrating for the daily routine.

The flow rate of 12-15 is suitable for Indian homes. Usually, a home water purifier comes with this flow rate only. Some advanced models have a higher flow rate of 20 liters per hour.

Select a water purifier with a reasonable flow rate.

6. Material used.

To make it lightweight & cost-effective, companies are manufacturing water purifiers in plastic.

Water in contact with non-food grade plastic is harmful to health if consumed for long.

Hence, it is important that the storage tank is made from food-grade plastic to maintain its purity.

7. Mineral addition Technology.

RO water purifier removes all minerals, salts & dissolved substances from water. It also removes all essential minerals from water that is necessary for humans. Consumption of such water will have an adverse effect on your health. 

Hence, manufacturing companies have introduced mineral addition technology. With the help of this method, essential minerals/salts are added back to purified water. It helps to keep a healthy balance of your body.

When choosing, ensure to have mineral additional, TDS controller, mineralizer in your water purifier to get benefits.

8. Display & alarm indicators.

Nowadays, all appliances are getting additional indicators to make operating appliances easy.

The on/off, empty/full tank displays are important to know the status of the water purifier. In addition, the latest models have filter failure, UV lamp failure alarms. It helps you to take action timely & effectively. With a timely resolution of the problem, you continue to get clean water & enhance the life span for your water purifier.

9. Brand, warranty & after sales-service.

The water purifier is related to the health of your family. It is crucial to purchase from a brand with the highest industry standard quality & trust. 

Mainly, all brands provide a warranty on their appliances. Some brand provides an extended warranty period. it should have at least 1 year warranty period for the model you have selected.

After using a few years, filters need a change with other regular maintenance. It is essential to have after-sales service must have strong support & quick action. It would be best if you chose a water purifier brand with a good presence in your area to give you better service later.

10. Price. 

The Final & vital point of decision making is price. It should be the last point in your discussion. We have kept it at end in our buying guide of best water purifier for home in India.
