Why Purefina
The same engineering discipline runs through everything we make
Every treatment system is designed with operational efficiency, energy consumption, water recovery and lifecycle cost in mind — not sized in isolation from how it will actually run. The same process control and quality assurance discipline governs our own bottling line, from source water through RO purification to the sealed bottle.
Where plants underperform, we investigate root cause and implement the engineering modification that fixes it, not just the symptom. Where our own product is concerned, that discipline is why every batch is licensed, tested and traceable.
Light & Pure
Bottled water, purified and mineralised
Purefina bottled water is extracted from a deep underground source and purified through a state-of-the-art reverse osmosis process, with the addition of superior essential minerals for taste and balance.

Care & storage
Getting the most out of every bottle
- Check that the safety and quality seal is intact before drinking; return the bottle if it has been tampered with.
- Check the expiry date printed on the bottle.
- Store in a cool, odourless place, away from direct sunlight.
- Handle the bottle with care and crush it after use for recycling.
Water and process engineering, delivered end to end
Purefina International operates two connected businesses: Light & Pure, our RO-purified bottled water brand, and a water treatment engineering practice that designs and delivers RO, UF, multimedia filtration and related systems for municipal and industrial clients.
On the engineering side, our work spans the full project lifecycle, from process design and documentation through construction, installation and commissioning. We design for sustainability and cost as much as for compliance — weighing operational efficiency, energy consumption, water recovery and lifecycle cost alongside treatment performance, to relevant engineering standards, quality assurance procedures, and applicable regulatory approvals.
On the product side, that same discipline governs our bottling operation in Taxila, Punjab — licensed by the Punjab Food Authority and certified to Pakistan Standards, from source water through purification to the sealed bottle.
