It is a well-known fact that drinking tap water can result in various water-borne diseases and other health issues. Thus, it is vital to install a water filter in your home. These devices use the latest technology and innovative features to treat the water and get rid of harmful toxins and microorganisms. They provide you with access to clean and fresh drinking water, ensuring good health for the entire family.
Importance of clean and safe drinking water
Safe water at home is one of the most basic requirements for human health. Since the human body is made of 60% water, we need to be hydrated for the physiological systems to function adequately. Clean drinking water helps maintain organ health and eradicate all kinds of toxins.
It is a well-known fact that unhygienic drinking water can give rise to various kinds of diseases, such as cholera, typhoid, and hepatitis A. The consumption of clean drinking water can eliminate the risk of such water-borne diseases.
Water type: Know your water type
| Water type | Description | Key feature |
| Tap water (Municipal) | Supplied by local authorities; treated to varying degrees. May contain fluoride and chlorine for health benefits. | Quality varies across regions; it needs additional filtering in some areas. |
| Borewell water | Drawn from underground wells in urban and rural areas. Quality depends on local geological conditions. | May contain minerals from the surrounding soil. |
| Mineral water | Bottled water from natural springs, enriched with essential minerals like calcium and magnesium. | Preferred for purity and nutritional value. |
| Spring water | Comes from natural springs with minimal processing, retaining natural minerals. | Known for freshness and natural taste. |
| Filtered/Purified water | Water purifiers remove contaminants using reverse osmosis, carbon filters, or UV treatment. | Ensures clean, safe drinking water at home. |
| Well water | Common in rural areas, quality depends on surrounding geology. | Regular testing is recommended for safety. |

How does a water filter for home remove contaminants
Advanced water purification technologies are designed to remove impurities, improve water quality, and ensure safe usage. These methods combine science and innovation to address growing concerns of clean water availability.
- Reverse Osmosis (RO): Uses a semi-permeable membrane to remove dissolved salts, heavy metals, and impurities, delivering clean and safe drinking water.
- Ultrafiltration (UF): Employs fine membranes to filter out bacteria, viruses, and suspended particles, ensuring microbiologically safe water without altering taste.
- Ultraviolet (UV) Purification: Utilises UV light to deactivate harmful microorganisms like bacteria and viruses, providing chemical-free disinfection.
- Activated Carbon Filtration: Removes chlorine, organic compounds, and odours, improving taste and smell while reducing harmful contaminants.
- Advanced Oxidation Processes (AOPs): Break down complex organic pollutants using powerful oxidants like ozone or hydrogen peroxide, ensuring thorough purification.
- Ion Exchange Technology: Replaces harmful ions such as calcium, magnesium, or nitrates with safer alternatives, reducing hardness and improving water quality.
- Electrodeionization (EDI) Combines ion exchange and electricity to continuously remove ions, producing ultra-pure water for industrial and medical use.
- Nanofiltration (NF) Filters out divalent and larger ions, pesticides, and organic matter, offering a balance between RO and UF for moderate purification needs.
Types of water filters for home use
There are several types of water filters, each with a different mechanism. Some water purifiers use a combination of two or more filters to offer better-quality drinking water.
Some of the most common filter types include the following:
| Purification method | Description | Key points |
| Reverse osmosis (RO) | Uses a semipermeable membrane to remove dissolved salts, impurities, and germs. | Effective for high TDS; requires high water pressure; wastes water; may alter taste. |
| Ultraviolet (UV) light | Uses short-wave UV radiation to destroy bacteria and viruses. | Removes 99.99% of harmful organisms; ideal for microbial contamination. |
| Ultrafiltration (UF) | Employs membrane technology with larger pores to filter microscopic particles. | Cannot remove dissolved solids; unsuitable for hard water due to low TDS capability. |

How to choose the best water filter for your home
When selecting water filters for your home, you must consider the following essential factors:
| Key factor | Description |
| Water quality | Assess your water source—high TDS water needs RO, while low TDS water benefits from UV or UF filters. |
| Filtration technology | Choose the right technology (RO, UV, UF) based on contaminants present in your water. |
| Capacity | Select a filter with a storage capacity that matches your family size and daily water consumption. |
| Maintenance | Opt for filters with easy maintenance, including replaceable cartridges and service availability. |
| Budget | Compare prices and long-term costs, including filter replacements and electricity usage. |
| Certification | Look for water filters with safety and quality certifications like ISI or NSF. |
| Additional features | Consider extra features like mineralisers or smart indicators for enhanced usability. |

How to install and maintain your water purifier
Installing a water purifier is straightforward when you follow the correct sequence, and regular filter replacement helps maintain safe drinking water and consistent purification performance.
- Connect the plumbing: Install the inlet pipe to the water supply and ensure the drain connection is secure with no leaks.
- Mount the purifier: Fix the unit securely on the wall or place it on a stable countertop, keeping it close to a water source and a power socket if required.
- Connect the inlet and outlet: Attach the inlet and outlet pipes, flush the system as recommended by the manufacturer, and check that the purifier operates correctly before use.
| Component | Replacement frequency | Sign of needed replacement |
|---|
| Sediment filter | Every 3–6 months | Reduced water flow or visible dirt build-up |
| Carbon filter | Every 6–12 months | Unpleasant taste or odour in drinking water |
| RO membrane | Every 1–2 years | Lower purification performance, reduced water output, or increased TDS levels |

Maintenance of water purifiers
You need to properly maintain the water purifier to ensure that you always get clean and safe drinking water. For this, you must consider the following things:
- Regular filter changes: Filters can get clogged with impurities as time passes, affecting their filtration capacity. Changing the filters according to the brand’s suggested timelines is critical.
- Sanitise the tank: Apart from the filters, there are several internal pipes and parts that result in the purifier functioning. While changing the filters, ensure that the other parts are sanitised as well. The exteriors should also be tidy and sanitised.
- Check for leakages: If you witness any drips or leakages, contact a professional immediately. It can cause harm to the machine, damaging its filtration capabilities.
