What Is an RO Filter & Why Is It Important for Kathmandu?
RO (Reverse Osmosis) is an advanced water purification technology that removes:
- Dirt and sediments
- Harmful chemicals (arsenic, fluoride, chlorine)
- Bacteria and viruses
- High TDS and heavy metals
In many areas of Kathmandu, Bhaktapur, and Lalitpur, water comes from:
- Deep-bore well
- Water tanker
- Municipal supply (KUKL)
- Underground sources
These sources often contain impurities that simple filters cannot handle. That’s why RO filters have become a must-have appliance for Kathmandu homes.
Who Should Use an RO Filter in Kathmandu?
You need an RO filter if:
✔ Your water has TDS above 300 mg/l
✔ You use underground water
✔ You get water tanker supply
✔ The water smells or tastes salty
✔ You want safe, purified drinking water for your family
If your water has low TDS, you can choose UV + UF, but most Kathmandu households benefit from RO systems because of mixed water sources.
