Why You Need a Water Purifier in India

India faces unique water challenges. According to reports from the Central Pollution Control Board, many rivers and groundwater sources are contaminated with industrial waste, pesticides, and bacteria. In states like Punjab and Rajasthan, high TDS (Total Dissolved Solids) levels make water taste salty or bitter. In coastal areas like Chennai, salinity is a big issue. Without proper purification, drinking such water can lead to health problems like gastrointestinal issues or long-term effects from heavy metals like arsenic and lead.

A good water purifier removes these impurities while retaining essential minerals. Under 20,000 INR, you can get models with RO (Reverse Osmosis), UV (Ultraviolet), and UF (Ultrafiltration) technologies—perfect for most Indian households. These not only ensure safety but also improve taste. Plus, with increasing awareness of wellness, features like alkaline water (which balances pH for better digestion) and mineral addition are becoming standard.

Buying Guide: What to Look for in a Water Purifier Under 20,000 INR

Before diving into specific models, let's break down the essentials. This section will help you evaluate options based on your needs.

1. Types of Purification Technology

• RO (Reverse Osmosis): Ideal for high TDS water (above 500 ppm), common in India. It uses a semi-permeable membrane to remove dissolved salts, heavy metals, and impurities. Most models under 20k combine RO with other tech for better efficiency.
• UV (Ultraviolet): Kills bacteria and viruses using UV light. Great for low TDS water but doesn't remove physical impurities.
• UF (Ultrafiltration): Filters out larger particles like cysts and colloids. Often paired with RO for comprehensive cleaning.
• Combination Systems: Look for RO+UV+UF for all-round protection. Some add alkaline or copper for health benefits.

In India, where water sources mix groundwater and municipal supplies, a multi-stage system (7-10 stages) is recommended.

2. Storage Capacity and Flow Rate

Families of 4-6 people need 6-9 liters of storage to avoid frequent refills. Flow rate (liters per hour) should be at least 15-20 LPH for quick access. Wall-mounted or tabletop designs save space in small Indian kitchens.

3. Water Recovery and Wastage

RO systems waste water during purification—up to 70% in older models. Newer ones recover 40-60%, saving thousands of liters yearly. This is crucial in water-scarce areas like Maharashtra or Karnataka.

4. Mineral Addition and pH Balance

RO can strip essential minerals, making water tasteless. Models with TDS controllers or mineralizers add back calcium, magnesium, and copper. Alkaline features raise pH to 7.5-8.5, promoting better hydration—a big trend in 2025.

5. Smart Features and Maintenance

App connectivity for filter alerts, auto-flush to extend membrane life, and LED indicators are handy. Check warranty (1-2 years standard) and AMC (Annual Maintenance Contract) costs—around 2,000-4,000 INR/year. Brands with widespread service networks like Kent or Aquaguard are preferable in tier-2 cities.

6. Installation and Power Consumption

Most require electricity (40-60W), so factor in power backups for outages. Free installation is common, but confirm plumbing needs.

7. Certifications and Budget Tips

Look for NSF, ISI, or BIS certifications for quality. Under 20k, prioritize value over gimmicks. Test your water's TDS (kits cost 200-500 INR) to choose the right type.

By focusing on these, you'll avoid common pitfalls like buying an overkill system for low TDS water.
