What is water purifier for?

According to a report by the World Health Organization, contaminated water is responsible for over 485,000 diarrheal deaths globally every year. This alarming fact alone justifies the critical need for clean drinking water and, by extension, the use of water purifiers. In countries like India, where groundwater contamination, high TDS levels, and seasonal pollutants are common, the need for domestic water purification becomes even more urgent.

This blog explores what a water purifier is for, its purpose, and the various technologies that make it essential in every household. It is especially useful for people looking to install the right kind of purifier at home for long-term health, hygiene, and peace of mind.

What Is a Water Purifier For?

A water purifier is a device designed to remove contaminants, impurities, and harmful substances from drinking water. It improves the taste, smell, and safety of water by eliminating particles like sediments, bacteria, viruses, heavy metals, and dissolved solids. The ultimate goal is to ensure the water is safe for human consumption.

In simpler terms, a water purifier ensures that the water you drink doesn’t harm your health—it turns raw, potentially dangerous water into clean, potable water.

What Is the Use of a Water Purifier?

The primary use of a water purifier is to protect you from waterborne diseases such as cholera, typhoid, and dysentery. However, modern purifiers go beyond microbial filtration. They also:

• Remove heavy metals like arsenic, fluoride, and lead

• Reduce Total Dissolved Solids (TDS) for better taste and safety

• Maintain essential minerals with TDS controllers or mineral cartridges

• Remove bad odor and chemical contaminants like chlorine

• Improve clarity and texture of water

These functions are particularly important in Indian households, where water sources vary between tap water, borewell, municipal supply, and tanker delivery—each with its own set of risks.

What Is the Purpose of Purifying Water?

The purpose of purifying water is not just filtration but transformation. Raw water can contain:

• Pathogenic bacteria and viruses

• Chemical fertilizers from agricultural runoff

• Industrial waste

• Excess salts and minerals

Purification neutralizes these threats to make the water usable for drinking, cooking, and even baby feeding. The goal is to provide reliable access to safe, clean, and healthy water, regardless of the source.

What Is the Aim of Water Purifier Technology?

The aim of a water purifier is to:

1. Ensure Health Safety – Prevent waterborne illnesses

2. Enhance Taste – Remove bad smells and metallic taste

3. Preserve Nutrients – Retain essential minerals

4. Reduce Dependency on Bottled Water – Offer long-term savings

5. Adapt to Local Conditions – Work effectively in both urban and rural India

With varying contamination levels across regions, water purifiers are designed to adapt purification techniques based on the TDS and pollutant profile of the source water.

What Is a Water Purifier for Home?

A water purifier for home is tailored for domestic use and is typically compact, user-friendly, and efficient. It comes in various forms:

1. Wall-Mounted Purifiers

These are space-saving units best suited for Indian kitchens. Explore available models here:

What Is a Water Purifier For in India?

In India, the use of a water purifier becomes more critical due to:

• High fluoride levels in some states

• Hard water with excessive calcium and magnesium

• Unreliable municipal supply

• Poor infrastructure in rural areas

• Seasonal diseases like jaundice and diarrhea

A domestic RO or RO+UV purifier becomes a household essential to combat these issues effectively.

5 Methods of Water Purification

Water can be purified using several methods, each suited to different conditions:

1. Boiling

Kills bacteria and viruses but does not remove dissolved salts or heavy metals.

2. Filtration

Mechanical filters remove dirt and sediments but not microbial or chemical contaminants.

3. Chlorination

Effective against pathogens but leaves a strong smell and potential harmful by-products.

4. UV Purification

Uses ultraviolet rays to destroy microorganisms. Ideal for low TDS water.

5. Reverse Osmosis (RO)

Removes 90–95% of TDS, heavy metals, and harmful substances. Best for high TDS and mixed-source water.

Water Purifiers vs Boiling: A Quick Comparison

When Do You Need a Water Purifier?

You definitely need a water purifier if:

• Your tap water tastes salty, metallic, or smells bad

• TDS level is above 300 ppm (use a TDS meter to check)

• You rely on borewell or tanker water

• You see white scaling on taps or utensils

• Children or elderly live in your household

• You want to reduce medical risks from contaminated water

Types of Water Purifiers for Homes

A. RO Purifiers

Best for high TDS areas. They use a semi-permeable membrane to remove 90%+ dissolved solids and contaminants.

B. UV Purifiers

Suitable for municipal water with low TDS but microbial risks.

C. UF (Ultrafiltration) Purifiers

Work without electricity and remove physical particles and some pathogens.

D. Gravity-Based Purifiers

Non-electric and useful for areas with treated or low-contaminant water.

How to Choose the Right Water Purifier for Your Home

• Check your water source: Borewell, municipal, tanker

• Measure TDS level: Use a digital TDS meter

• Choose technology accordingly: RO for TDS >500 ppm, UV for microbial concerns, UF for backup

• Decide installation type: Wall-mount, under-sink, or table-top

• Check certification: Prefer purifiers with NSF, ISI, or similar safety ratings

Water Purification and Health: What Science Says

Long-term exposure to contaminated water can cause:

• Gastrointestinal infections

• Dental and skeletal fluorosis (due to high fluoride)

• Kidney damage (due to heavy metals)

• Liver dysfunction

• Poor child development

Water purifiers eliminate these health risks by providing consistently clean water suitable for all age groups.

Challenges with Tap and Borewell Water in India

• Borewell Water: Often has high TDS, iron, and heavy metals.

• Municipal Supply: Treated, but still prone to pipeline contamination.

• Tanker Water: Unregulated and often of poor quality.

Given these realities, relying solely on boiling or traditional methods isn’t enough. A modern domestic water purifier is essential.
