Jahen and Jos Scientific Solutions Pvt. Ltd. is a deep-tech startup incubated at IIT Madras Research Park, building next-generation RO filtration technology for clean, safe water.

Founded in 2022, we develop and commercialize water purification solutions based on Spiral Filtration Technology, licensed from IIT Madras, Chennai. Unlike conventional carbon filters, our spiral design eliminates channelization, increases water-carbon contact time, and ensures full utilization of the loaded carbon — making it up to three times more efficient than commercially available carbon filters.
Our flagship CARBO-A Series — Spiral Pre-Carbon (Carbo A1), Spiral Post-Carbon (Carbo A2), and Alkaline Mineral cartridges (Carbo A3) are engineered to:
We're committed to transforming water purification with technology that makes drinking water safer, healthier, and better-tasting — for homes and businesses alike.

High Contact Time

High Contact Time

The spiral pathway guides water along a longer route through the carbon media, helping reduce direct bypass and distribute flow across more of the carbon. This can improve effective water–carbon contact and media use. Actual contact time depends on cartridge volume, porosity, and flow rate.

Eliminate Channelization

Eliminate Channelization

The spiral pathway is designed to guide water more evenly through the carbon media, helping limit preferential flow paths and reduce channeling. Actual performance depends on cartridge design, carbon packing, flow rate, and operating conditions.

Effective Utilization of Carbon

Effective Utilization of Carbon

The spiral pathway is designed to distribute water more evenly through the carbon bed, helping reduce bypass and make better use of the available carbon media. Actual media utilization depends on flow rate, carbon packing, and operating conditions.


Spiral Flow Pre-Carbon: Supporting RO Membrane Protection

Spiral Flow Pre-Carbon: Supporting RO Membrane Protection

The CARBO-A1 helps reduce free chlorine and selected organic compounds before water reaches the RO membrane. Its spiral design guides water through the carbon media to support more even flow and contact, helping limit bypass. Performance depends on water quality, flow rate, carbon condition, and timely cartridge replacement.
