🔍 What is an RO Water Purifier?

RO (Reverse Osmosis) is a water purification process that removes dissolved solids, heavy metals, salts, and harmful chemicals by forcing water through a semipermeable membrane.

✅ Key Features of RO Purifiers:

Removes TDS (Total Dissolved Solids)
Eliminates lead, arsenic, fluoride, and other impurities
Improves taste, color, and odor of water
Includes multiple filters (sediment, carbon, RO membrane)

🔍 What is a UV Water Purifier?

UV (Ultraviolet) water purifiers use ultraviolet light to kill bacteria, viruses, and pathogens present in water. Unlike RO, UV systems do not remove dissolved salts or chemicals, but they disinfect water effectively.

✅ Key Features of UV Purifiers:

Kills 99.9% of germs and viruses
No change in TDS or essential minerals
Faster purification process
Low maintenance and energy-efficient

🏠 Which Water Purifier Is Best for Your Home?

The right purifier depends on your water source and the quality of water supply in your area.

✅ Choose an RO Water Purifier if:

You receive borewell or tanker water
Water has high TDS (>300 ppm)
Water tastes salty or metallic
You want comprehensive purification

✅ Choose a UV Water Purifier if:

You receive municipal or treated water
Water has low TDS (<200 ppm)
You only want germ-free water
You want faster, low-maintenance purification

💡 Pro Tip: In some areas, a RO+UV combo purifier offers the best of both worlds — removing physical, chemical, and biological impurities.

🧰 Maintenance & Service

Both RO and UV purifiers need regular servicing to stay effective.

RO purifiers require filter and membrane replacement every 6–12 months.
UV purifiers need UV lamp replacement and basic cleaning.

📝 Final Thoughts

Both RO and UV water purifiers offer excellent purification — but their effectiveness depends on your local water quality.
If your water contains high TDS and heavy metals, go for RO.
If you're mainly concerned about germs in low-TDS water, UV is a great fit.

Whichever purifier you choose, make sure you schedule regular maintenance to keep your drinking water pure and safe.
