Water Purifier in Delhi

A water purifier is a device that removes impurities, contaminants, and harmful microorganisms from drinking water using technologies like RO, UV, and UF. The best water purifier for your home depends on water quality, TDS levels, and daily usage needs.

Introduction to Water Purifiers

Clean drinking water is essential for health, yet most households still consume water containing impurities like bacteria, dissolved solids, heavy metals, and chemical residues. With rising pollution levels and deteriorating water sources, installing a water purifier has become not just a lifestyle choice but a necessity for every home.

Modern water purifiers use advanced purification technologies like Reverse Osmosis (RO), Ultraviolet (UV), Ultrafiltration (UF), Activated Carbon, Copper-infused systems, and Mineralizers to ensure that the water you consume is 100% safe, healthy, and great-tasting.

The global demand for home water purification systems has rapidly grown, especially in urban areas, where TDS levels and contamination are high. Whether you rely on well water, borewell water, tanker water, or municipal supply, choosing the right water purifier can significantly impact your family’s health.

In this detailed guide, you will learn everything you need to know — from types, benefits, pricing, top brands, comparisons, and maintenance tips, to expert recommendations. The goal is to help you confidently select the best water purifier for home use.

What Is a Water Purifier?

A water purifier is an appliance designed to remove physical, chemical, and biological impurities from water using filtration technologies like RO, UV, and UF. It improves taste, odor, and overall drinking water quality by eliminating contaminants such as heavy metals, dirt, viruses, bacteria, pesticides, and chlorine.

How Water Purifiers Work 

• RO purifiers: Remove TDS and heavy metals

• UV purifiers: Kill viruses and bacteria

• UF purifiers: Remove suspended particles

• Carbon filters: Remove chlorine and improve taste

• Mineralizers: Add essential minerals back to water

Types of Water Purifiers Explained 

Different water purifiers suit different water conditions. Below is a detailed overview of all commonly used purification technologies.

3.1 RO Water Purifier

RO (Reverse Osmosis) is the most popular purification technology used in homes today. It forces water through a semi-permeable membrane that blocks dissolved solids, heavy metals, fluoride, arsenic, and salt.

✔ Best for: High TDS water
✔ Removes: Chemical impurities, metals, TDS
✔ Example product:

3.2 UV Water Purifier

UV systems use ultraviolet rays to destroy bacteria, viruses, and pathogens. They are ideal for homes with relatively clean water but biological contamination.

✔ Best for: Municipal water
✔ Removes: Microorganisms
✔ Does NOT remove: TDS, metals

3.3 UF Water Purifier

UF purifiers use a hollow fiber membrane that eliminates suspended particles and certain microorganisms, without electricity.

✔ Best for: Low-TDS water
✔ Removes: Mud, dirt, bacteria
✔ Works without power

3.4 Activated Carbon Water Filters

Activated carbon absorbs chlorine, bad taste, foul smell, and organic chemicals from drinking water.

✔ Best for: Improving taste
✔ Usually combined with RO/UV

3.5 Alkaline Water Purifiers

Alkaline systems increase the pH of water and add essential minerals like calcium, magnesium, and potassium.

✔ Good for: Better hydration, digestion
✔ Often paired with RO

3.6 Gravity-Based Water Purifiers

These purifiers work without electricity, using gravity to filter water.

✔ Best for areas with low contamination
✔ Budget-friendly
