For those who rely on untreated water sources, the risks are even higher. But there’s a solution that offers peace of mind and ensures every sip you take is truly refreshing and healthy: a water purifier.

This comprehensive guide is intended to help you navigate the world of water purifiers and find the perfect one for your home and family. We’ll take you through the different types of contaminants, the various purification technologies available, and the factors you should consider based on your specific needs and budget. By the end, you’ll be equipped with the knowledge to make an informed decision and transform your tap water into a source of pure, safe, and delicious drinking water.

Understanding water contaminationThe water we drink might look clear and refreshing, but it often harbours a hidden world of contaminants that can pose serious health risks. Let’s have a closer look at the types of contaminants lurking in your water and the technologies that can safeguard you from them.

Types of Water Contaminants:

• Biological contaminants: These include bacteria, viruses, and parasites that can cause diseases like cholera, typhoid, and dysentery. They often originate from sewage or animal waste contamination.
• Chemical contaminants: This category encompasses a wide range of substances, including heavy metals like lead and arsenic, pesticides, industrial chemicals, and chlorine by-products. Long term consumption of these contaminants can have negative health effects, including neurological damage, organ failure, and even cancer.
• Physical contaminants: This category includes visible impurities like sand, silt, and rust, as well as microscopic particles like asbestos fibres that give the water a diluted look. While not always harmful, they can affect the taste and appearance of water and potentially damage plumbing systems, causing rusting and blockage.
• Dissolved solids: These are invisible substances dissolved in water, including minerals like calcium and magnesium (which contribute to water hardness) and salts. While some minerals are essential, excessive levels can affect taste, cause scaling, and potentially lead to health issues.

What are the contaminants in common water sources:

Water Purification Technologies

Before you finalise a water purifier, it is important to understand the different technologies used to ensure pure and safe drinking water. Following are some of the popular purifications methods used in modern water purifiers:

• Reverse Osmosis (RO): This is the most commonly used technology in water purifiers that utilises a semipermeable membrane to filter out dissolved solids, heavy metals, and other impurities. It’s effective for water with high TDS levels but can remove essential minerals.
• Ultraviolet (UV): UV light effectively eliminates bacteria and viruses by disrupting their DNA. It’s best suited for low TDS water, often used in combination with RO to ensure complete purification.
• Ultrafiltration (UF): This membrane-based technology removes suspended particles, bacteria, and viruses. It doesn’t remove dissolved solids and is suitable for water with low to moderate TDS levels.
• Microfiltration (MF): Similar to UF, MF removes suspended particles and some bacteria. It’s often used as a pre-filter for RO systems.
• Copper Purification: A traditional and culturally significant method in India, copper purification involves storing water in copper vessels. This process is believed to have antimicrobial properties, killing bacteria and potentially offering health benefits due to the trace amounts of copper ions released into the water. However, it’s important to note that copper purification alone might not be sufficient to remove all contaminants, especially in areas with high TDS or heavy metal contamination.
• Gravity-based Purification: This simple yet effective method relies on gravity to filter water through multiple layers, typically including activated carbon and sediment filters. It’s suitable for removing suspended particles and some impurities, making it a more affordable option for basic purification needs. However, it might not be as effective as RO or UV for removing dissolved solids or certain contaminants. It is effective for people living in areas with irregular power supply.

How to maintain your water purifier:

Proper maintenance is key to ensuring your water purifier delivers clean and safe drinking water consistently. Neglecting maintenance can lead to reduced performance, shorter filter lifespan, and potential health risks. Here’s what you need to know:

Filter Replacement:

Timely filter replacement is crucial for effective purification. Each filter type has a different lifespan, so it’s important to follow the manufacturer’s recommendations for replacement intervals. Here’s a general guideline:

• Sediment Filter: Replace every 3–6 months.
• Pre-Activated Carbon Filter: Replace every 6–9 months.
• RO Membrane: Replace every 1–2 years.
• UV Lamp: Replace every 1–2 years.
• UF Membrane: Replace every 1 year.
• Post-Carbon Filter: Replace every 9–12 months.

Signs that your filters need replacement:

• Slow Water Flow: This could indicate a clogged sediment filter or a worn-out RO membrane.
• Bad Taste or Odour: A foul taste or odour suggests that the carbon filter is no longer effective.
• Cloudy or Discoloured Water: This could be due to a failing sediment or UF membrane.
• Indicator Lights (if applicable): Some purifiers have indicator lights that signal when filters need replacement.

Cleaning and sanitisation:

Regular cleaning and sanitisation are essential to prevent the growth of bacteria and algae inside the purifier. Here are some tips:

• External cleaning: Wipe the exterior with a damp cloth and mild detergent.
• Tank cleaning: Empty and clean the storage tank with warm water and a mild detergent every 1-2 weeks.
• Filter housing cleaning: Disassemble the filter housing and clean it with a soft brush and soapy water.
• UV lamp cleaning: Clean the UV lamp with a soft cloth and rubbing alcohol.
• Sanitisation (optional): Sanitise the tank and internal parts with a food-grade sanitizer as per the manufacturer’s instructions.
