Water Purifiers

Choosing the right water purifier for your home in 2024 can be a complex decision due to the wide variety of options available. This guide will help you understand the essential factors to consider, the types of water purifiers, their power consumption, star ratings, and other features to look for.

Types of Water Purifiers

Water purifiers come in various types, each suited for different water conditions:

Reverse Osmosis (RO)

Best For
High TDS (Total Dissolved Solids) levels.
Uses a semi-permeable membrane to remove dissolved salts, chemicals, and heavy metals.
Requires electricity, can waste some water during the purification process.

Ultra-Filtration (UF)

Best For
Water with bacteria and viruses but no heavy metals.
Uses a hollow fiber membrane to remove particles and microorganisms.
Does not require electricity, but doesn’t remove dissolved salts.

Activated Carbon Filters

Best For
Removing chlorine, pesticides, and bad odors.
Uses activated carbon to absorb contaminants.
Often used in combination with other purification methods.

Gravity-Based Purifiers

Best For
Areas with low TDS and where electricity is unreliable.
Uses gravity to pass water through a purification cartridge.
Low maintenance and cost, but slower purification process.

Assessing Water Quality and Source

Before choosing a water purifier, it’s crucial to understand the quality of water you receive:

TDS Level

Measure the Total Dissolved Solids in your water. If the TDS level is above 500 ppm, an RO purifier is recommended.

Presence of Contaminants

Identify other contaminants like heavy metals, bacteria, viruses, and chemicals.

Water Source

Determine if your water comes from a borewell, municipal supply, or other sources, as this affects the choice of purifier.

Storage Capacity

When choosing a purifier, consider both your family size and usage patterns. Select a purifier with a storage capacity that meets your family’s daily water consumption needs. Additionally, think about how often you use purified water for drinking, cooking, and other purposes to ensure the purifier can handle your household’s requirements.

Small Families (2-4 members)

5-8 liters.

Large Families (5+ members)

10-12 liters.

Power Consumption

Water purifiers, especially those with RO technology, consume varying amounts of power. Choosing an energy-efficient model can help reduce electricity bills, so look for purifiers with energy-saving modes and low power consumption.

UF & Gravity Purifiers

Do not require electricity.

RO Purifiers

Typically consume between 25 to 60 watts.

UV Purifiers

Generally consume around 8 to 20 watts.

Star Rating and Energy Efficiency

Energy efficiency is indicated by the star rating system, which ranges from 1 to 5 stars:

Higher Star Ratings

Indicate better energy efficiency. A 5-star rated purifier will be the most energy-efficient.

Impact on Costs

More energy-efficient purifiers will save money in the long run through lower electricity consumption.
