How to Choose the Right Water Filter for Indian Households Based on Water Type

RiverSoft | 09 June 2025

Did you know that the water that you receive, through borewells, tankers, or from the municipality, is slowly harming your skin, hair, and general health? According to reports, about 37.7 million people are affected by waterborne diseases each year. That’s why picking the right water filter for hard water isn’t just a home upgrade, it’s a necessity.

The variety of hard water filters on the market can make it overwhelming to choose the best one. But it gets much easier if you know what to look for. 

Common Water Sources in India

It is important to choose your hard water filter according to the water supply you receive:

Groundwater (Borewell)

Groundwater contains large minerals and can be high in TDS (total dissolved solids), which can cause scaling in your appliances and can be salty to taste.

Municipal Corporation Water

Water supplied by the municipal corporation is treated by the local government. TDS is usually very low, but the water may still contain chlorine and harmful microbes.

Tanker Water

Usually supplied when water availability is scarce. The water in such cases can be high in TDS levels or may be chemically treated for filtration.

Mixed Sources

If you use a mix of sources, chances are the quality of water varies week to week.

How to Identify Your Water Type

Wondering how to test your water quality? Follow these easy tests to identify your water type to choose the right water filter for hard water.

1. DIY Checks:

Do your dishes get white stains after using water? Or does it taste overly salty or sticky? This happens when the water is high in minerals or has high TDS.

2. TDS levels

You can test the TDS ppm (parts per million) using a simple TDS meter, which usually ranges from ₹200–₹500.

  • <300 ppm: Low TDS

  • 300–600 ppm: Medium TDS levels

  • 600 ppm: High TDS (often hard water)

3. Lab Testing:

For accurate results on the amount of fluoride, lead, nitrates, and bacteria, testing water at an NABL-certified laboratory is advised.

Types of Water Filters Available in India

Here are some of the varieties of hard water filters available in India and their roles.

  • RO (Reverse Osmosis)

Gets rid of salt, lead, and arsenic in water. Borewell and tanker water with a high TDS level can be treated with this solution.

  • UV (Ultraviolet Purification)

Uses UV rays to eliminate any viruses and bacteria in the water. Works best for water with low mineral content, like municipal supply.

  • Carbon Filter

Gets rid of chlorine, unwanted smells and different pesticides. It improves the smell and taste of the water.

  • Sediment Filters

Traps big particles, dust, and rust, and helps protect the main filter from pollution.

  • Mineral Filters

Restores minerals such as calcium and magnesium after the RO process to improve the taste of the water.

Best Filter for Each Water Type

Here’s a simple table to identify which type of hard water filter is ideal for your household:

Water Type

Common Issues

Recommended Filter Type

Borewell (Groundwater)

High TDS, hardness, and heavy metals

RO + UV filters

Municipal Corporation

Chlorine, bacteria, low TDS

UV + Filters with Activated Carbon

Tanker Water

Mixed levels of TDS, chemical smell

RO + UV Filters

Mixed Sources

Inconsistent quality

RO + UV + Filters for high TDS

Factors to Consider Before Investing in A Water Filter

While shopping, keep the following factors in mind:

  • TDS Level:

This is one of the first signs to look for. If the ppm level is above 500, installing an RO is strongly advised.

  • Maintenance:

Most filters should be serviced every 6-12 months. Look into the maintenance charges before investing in a hard water filter. 

  • Space and Funds:

Consider the space available to you before installing a water filter for hard water. If the space is limited, consider going for a smaller system that fits directly onto your taps.
