Choosing the right water purifier for your home is essential for ensuring you and your family have access to clean, safe, and great-tasting water. There are different types of water purifiers for homes available on the market, each designed to tackle different types of contaminants and meet specific needs; finding the performing purifier can be overwhelming.
What kind of drinking water is best for drinking?
Selecting the right water purifier can significantly impact your family’s health and well-being. Here’s a quick guide to the different types of water purifiers available for home use, each has its own unique features to help you make an informed decision.
Everyone should know what kind of water is good for drinking. The source of water and the quality are the most important factors. To ensure water is drinkable, we have to check the TDS, hardness, and salinity of the water. TDS stands for total dissolved solids in water, such as salts, minerals, metals, and ions. To check these impurities, a TDS meter is used, and the TDS value of water should not be more than 300 PPM.

2. Ultraviolet (UV) Water Purifiers
UV purifiers use UV light to kill bacteria and viruses present in water. These systems are generally compact and easy to install, making them a popular choice for households. However, they do not remove any dissolved impurities, so they are usually used in combination with other purification methods.
Key Features:
- Disinfects Water: Uses UV light to kill bacteria and viruses without altering the taste or chemical composition.
- Chemical-Free: No chemicals are used, preserving the natural taste of water.
- Low Maintenance: Requires minimal maintenance compared to other types.
- Suitable for: Municipal water supplies with low TDS levels.
| Advantages | Disadvantages |
|---|---|
| High purification rate | Germs remains in purified water |
| Low maintenance cost | Taste of water not improve |
| Low energy consumption | Does not work for mud water |
| Less Manual cleanig | Does not remove toxic chemicals |
| Keep essential minerals |

3. Activated Carbon water Filters
Activated carbon filters use a porous material to remove impurities from water. They are effective in removing chlorine, sediment, and organic compounds but do not work against heavy metals or microorganisms. These filters have a relatively low maintenance cost and can be easily installed on faucets or in pitchers.
Key Features:
- Physical Filtration: Uses a membrane to filter out bacteria, cysts, and other microorganisms.
- No Electricity Required: Operates without electricity, making it eco-friendly and cost-effective.
- Durable Filters: Long-lasting filters that are easy to clean and maintain.
- Suitable for: Areas with low TDS and relatively clear water.
| Advantages | Disadvantages |
|---|---|
| Removes pesticides and toxic chemicals | Activated Carbon does not remove dissolved salts |
| Removes heavy metal particles | Does not removes bacteria and viruses |
| water smells and tastes good |
4. Distillation water purifier
Distillation systems heat water until it turns into steam, leaving behind impurities like bacteria and heavy metals. The steam is then condensed back into liquid form for consumption. While this method effectively removes contaminants, it also strips away essential minerals from the water
Key Features:
- Chlorine Removal: Excellent at removing chlorine, sediment, and volatile organic compounds.
- Improves Taste and Odor: Enhances the taste by removing contaminants that cause odor.
- Simple to Install: Easy setup that doesn’t require plumbing changes.
- Suitable for: Households using municipal water with noticeable chlorine taste or smell.

5. Ion Exchange water Filters
Ion exchange filters use a resin to remove minerals like calcium and magnesium from the water, which can cause hardness or scale buildup. These systems are effective in improving the taste of water but do not remove any other impurities. They also require regular replacement of the resin cartridges.
Key Features:
- Softens Water: Removes hardness-causing ions like calcium and magnesium, preventing scale buildup.
- Improves Soap Efficiency: Helps soaps and detergents work more effectively.
- Regeneration Required: Requires periodic regeneration with salt solution.
- Suitable for: Areas with hard water issues.
6. Gravity-Based water Purifiers
Gravity-based purifiers use the natural force of gravity to filter water through a combination of sediment and activated carbon filters. They do not require electricity or running water, making them suitable for use in areas with no access to these amenities. However, they may not be as effective in removing certain impurities compared to other methods.
Key Features:
- Basic Filtration: Removes large particles like sand, silt, and dirt.
- Protects Appliances: Often used as a pre-filter to prolong the life of other purification systems.
- Low Cost: Economical and easy to replace filters.
- Suitable for: Initial stage filtration to protect advanced purification systems.

FAQs:
Which type of water purifier is best for Indian homes?
The best purifier depends on your water quality. RO purifiers work best for hard water with high TDS, while UV purifiers are suitable for water with biological contamination.
What is TDS in water and why does it matter?
TDS (Total Dissolved Solids) indicates the concentration of minerals in water. Higher TDS may require an RO purifier, while lower TDS can be managed with UV/UF purifiers.
Do all water purifiers require electricity?
No. Non-electric purifiers such as gravity-based filters work without power, but advanced systems like RO and UV need electricity.

Frequently Asked Questions (FAQs)
1. Which type of water purifier is best for my home?
The best type depends entirely on your source water quality:
For High TDS (Total Dissolved Solids) / Hard Water (above 300 ppm): A Reverse Osmosis (RO) purifier is necessary to remove dissolved salts, heavy metals, and improve taste.
For Low TDS / Municipal Water (below 300 ppm): A UV (Ultraviolet) or UF (Ultrafiltration) purifier is usually sufficient to kill bacteria and viruses while retaining natural minerals.
Combined Water Sources: A multi-stage purifier using RO + UV + UF is the safest choice if your water source is unknown or changes frequently (e.g., switching between borewell and municipal supply).
What is TDS in water, and why does it matter for my purifier choice?
TDS stands for Total Dissolved Solids, which is the concentration of inorganic salts, minerals, and metals (like calcium, magnesium, and sodium) dissolved in water.
Importance: High TDS levels (above 500 ppm) give water a metallic or salty taste and can damage appliances. An RO purifier is specifically designed to reduce high TDS. If your TDS is already low, using an RO can unnecessarily remove beneficial minerals.
Do all water purifiers require electricity to operate?
No.
Electric: RO and UV purifiers require electricity to run the pump (RO) or the UV lamp.
Non-Electric: UF (Ultrafiltration) and Gravity-Based purifiers work solely on water pressure or gravity and are ideal for areas with no power supply and low TDS water.
How often should I replace the filters in my water purifier?
Filter replacement frequency depends on the filter type, water quality, and usage:
Pre-Filters (Sediment & Carbon): Typically need replacement every 6 to 12 months as they take the bulk of the initial contamination.
RO Membrane: Usually lasts longer, requiring replacement every 2 to 3 years, provided the pre-filters are changed on time.
UV Lamp: Typically replaced every 12 months or when the system alerts you, as its germicidal effectiveness decreases over time.
Always follow the manufacturer’s specific recommendations and watch for signs like a slow flow rate or a change in water taste/smell, which indicate a clogged filter.
