Complete Guide to Water-purifiers
Water purifiers remove dissolved impurities, bacteria, viruses, sediments, chemicals, and hardness from drinking water. Modern purifiers use multi-stage technologies such as RO, UV, UF, activated carbon, alkaline boosters, copper charging, and mineralizers to deliver clean, safe, and great-tasting drinking water. They are essential for homes, offices, hospitals, and commercial establishments with varying TDS and water quality levels.
Types of Water-purifiers
Uses semi-permeable membrane to remove dissolved salts, heavy metals, and chemicals. Best for high-TDS water (>300 ppm). Ensures safe drinking water even from borewells.
Uses UV lamp to kill bacteria and viruses. Suitable for low-TDS municipal water where chemical contamination is minimal.
Uses hollow fiber membrane to remove bacteria, cysts, and sediments. Works without electricity. Suitable for low-TDS or chlorine-treated water.
Combines RO, UV, and UF technologies for maximum purification in mixed water sources. Suitable for cities with varying TDS levels.
Adds alkaline minerals to increase pH level of water, improving taste and neutralizing acidity. Popular for health-conscious users.
Infuses copper ions into purified water to provide antioxidant and antimicrobial benefits. Mimics traditional copper storage vessels.
Uses activated carbon and UF filters without electricity. Suitable for low-TDS water and rural areas.
Installed below the kitchen counter with a dedicated tap. Saves countertop space and offers premium concealed installation.
High-capacity purifiers used in hotels, hospitals, factories, and schools. Supports large-scale purification from 25 LPH to 500+ LPH.
Provides purified hot, cold, and ambient water. Ideal for offices and premium homes requiring convenience.
Adds essential minerals after purification and maintains balanced TDS for better taste.

Frequently Asked Questions
Q: Which purifier is best for borewell water?
A: RO or RO+UV+UF is best for borewell or high-TDS water (>300 ppm).
Q: Do RO purifiers waste water?
A: Traditional RO systems waste water, but modern zero-wastage and recovery RO systems minimize loss.
Q: How often should filters be replaced?
A: Pre-filters: every 6–12 months; RO membrane: every 2 years depending on usage.
Q: Is alkaline water healthier?
A: Alkaline water may improve taste and reduce acidity, but health benefits vary by individual.
Q: Which purifier is best for municipal corporation water?
A: UV or UV+UF purifiers are suitable as municipal water usually has low TDS.
Q: Does UV kill all bacteria?
A: UV kills bacteria and viruses but does not remove dissolved solids. Use RO+UV if TDS is high.
