Comprehensive Water Purifier Buying Guide for Indian Consumers

The Comprehensive Water Purifier Buying Guide for Indian Consumers

Water is an essential resource for all living beings, and access to clean, safe drinking water is crucial for maintaining good health.

In India, where water quality can vary significantly from one region to another, water purifiers have become indispensable appliances for households.

With a plethora of options available in the market, choosing the right water purifier can be a daunting task for Indian consumers.

This comprehensive guide aims to educate consumers about different types of water purifiers, their technologies, and factors to consider while making an informed decision.

The Need for Water Purification in India

India, being a diverse country, faces a wide range of water quality challenges.

Many regions grapple with issues such as high levels of dissolved impurities, microbial contamination, heavy metals, and chemicals in their water supply.

These contaminants can lead to waterborne diseases and long-term health problems.

Hence, it becomes crucial to invest in a reliable water purifier to ensure the water consumed is safe and clean.

Types of Water Purifiers

There are several types of water purifiers available in the Indian market, each utilizing different technologies to purify water.

Understanding the differences between them can help consumers make an informed choice:

Reverse Osmosis (RO) Purifiers:

RO water purifiers are popular in India due to their ability to remove dissolved impurities, heavy metals, and microbial contaminants effectively.

They use a semipermeable membrane to separate impurities from water, providing clean and safe drinking water.

However, RO purification also removes essential minerals from the water, necessitating the need for a mineralizer to re-introduce these minerals.

Ultrafiltration (UF) Purifiers:

UF purifiers work on a similar principle to RO purifiers but use a larger pore size in their membranes.

They can remove larger particles, bacteria, and cysts but are not as effective in eliminating dissolved impurities.

UF purifiers are more suitable for areas with relatively low TDS (Total Dissolved Solids) levels in the water.

UV (Ultraviolet) Purifiers:-

UV water purifiers use ultraviolet radiation to deactivate and kill bacteria, viruses, and other microorganisms present in the water.

They are effective in disinfecting the water but do not remove dissolved impurities.

Hence, a UV purifier is often used in combination with other purification technologies like UF or RO to provide comprehensive purification.

Activated Carbon Purifiers:

Activated carbon purifiers use activated carbon filters to remove chlorine, organic compounds, and some pesticides from the water.

While they are effective in improving taste and odor, they are not suitable for areas with high levels of dissolved impurities and microbial contamination.

Gravity-Based Purifiers:

These purifiers use the principle of gravity to purify water.

They often incorporate UF or activated carbon filters and do not require electricity to operate.

Gravity-based purifiers are suitable for areas with a relatively low level of contamination and are a cost-effective option for many Indian households.

Factors to Consider When Buying a Water Purifier

Choosing the right water purifier involves considering various factors that align with the specific needs of a household.

Here are the key factors to keep in mind:

Water Quality and Source:

The first step is to get the water in your area tested to understand its quality.

Different water sources may have varying levels of impurities, TDS, and microbial contamination.

Based on the test results, you can choose a water purifier with the appropriate technology to address those specific contaminants.

Purification Technology:

As discussed earlier, various water purification technologies are available, and the choice depends on the water quality.

If the TDS levels are high, an RO purifier might be necessary, while a UV purifier could be sufficient for water with low TDS levels.

Storage Capacity:

The storage capacity of the water purifier is essential, especially in areas with irregular water supply.

Look for a purifier with an adequate storage tank to ensure a continuous supply of purified water.

Purification Speed:

Consider the purification rate of the water purifier, as it determines how quickly it can fill up the storage tank.

A faster purification rate is beneficial for large households or during times of high water usage.

Maintenance and After-Sales Service:

Regular maintenance is crucial to keep the water purifier functioning optimally.

Inquire about the maintenance requirements and the availability of service centers in your area before making a purchase.

Power Consumption:

For electric water purifiers, check the power consumption to ensure it doesn’t add significantly to your electricity bill.

Energy-efficient models are ideal for reducing long-term costs.


Look for certifications from reputable organizations such as the Bureau of Indian Standards (BIS), NSF International, or Water Quality Association (WQA).

These certifications validate the performance and quality of the water purifier.

User Reviews and Ratings:

Research customer reviews and ratings of the shortlisted models to gain insights into their real-world performance and durability.


Set a budget based on your requirements and compare various models within that price range to find the best value for money.

Maintenance and Care

To ensure the longevity and efficiency of your water purifier, regular maintenance is necessary. Follow these general maintenance tips:

Filter Replacement:

Regularly replace the filters as per the manufacturer’s instructions. Neglecting filter replacement can compromise the purification effectiveness.


Clean the exterior of the purifier and storage tank regularly to prevent the buildup of dirt and bacteria.


Periodically sanitize the water storage tank and internal parts of the purifier to prevent bacterial growth.

Professional Servicing:

Schedule periodic servicing by authorized technicians to address any technical issues and maintain the purifier’s performance.


Investing in a water purifier is a crucial step toward ensuring the health and well-being of your family.

With the myriad of options available in the Indian market, it is essential to understand the different types of water purifiers and factors to consider when making a purchase decision.

By analyzing the water quality in your area and matching it with the appropriate purification technology, you can make an informed choice.

Regular maintenance and care will keep the water purifier running efficiently for years to come, providing you with safe and clean drinking water for a healthier life.

Remember to check for certifications and read customer reviews to gain insights into the performance of the water purifier you’re interested in.

Happy water purification shopping!
