RO vs UV vs UF: What Is a Water Purifier?
A water purifier is a home appliance designed to remove:
- Impurities
- Harmful contaminants
- Excess minerals
- Microorganisms
from water before drinking.
Different purification systems use different technologies depending on water quality.
Common water problems include:
- Hard water
- Bad odor
- Muddy water
- High TDS
- Chlorine taste
Water purifiers help improve both safety and taste.
RO Water Purifiers
RO stands for Reverse Osmosis.
RO purifiers use a special membrane to remove:
- Dissolved salts
- Heavy metals
- Excess minerals
RO systems are commonly recommended for:
- Borewell water
- High TDS water
- Hard water areas
- Bacteria
- Viruses
- Microorganisms
These systems work well for:
- Municipal water
- Low TDS water
UF Water Purifiers
UF means Ultrafiltration.
UF systems remove:
- Suspended particles
- Dirt
- Some microorganisms
without electricity in some cases.
They are suitable for:
- Basic filtration
Which Is Better?
Many buyers become confused when comparing purification technologies.
RO Purifier Advantages
- Removes dissolved impurities
- Suitable for hard water
- Better for high TDS
UV Purifier Advantages
