Praan unveils sustainable air purification technology

The company has developed filterless air purification technology for small and large spaces using Ansys’ best-in-class simulation solutions.

US and India-based technology startup Praan, Inc. (Praan) developed its latest filterless air purification technology using Ansys’ industry-leading simulation solutions. The company’s advanced technology includes filterless purifiers for indoor air in large spaces with near-zero maintenance costs, and an advanced tablet-based activated carbon filter.

To help mitigate the worldwide problem of air pollution, the company has designed the MK One and MK Two for large spaces. The advanced air purification technologies — designed with Ansys® Fluent® computational fluid dynamics capture polluted air, separate microscopic particulate matter (particle pollution) into a collection chamber, and release cleaner air back into the atmosphere. Additionally, it offsets any carbon dioxide emitted during manufacturing through afforestation or direct air capture methods, making all their products net-zero.

Angad Daryani, Founder and Chief Executive Officer, Praan, said, “With Ansys simulation, our team significantly reduced the development time of functional prototypes from four and a half years to 45 days. Without simulation, it would have cost tens of millions of dollars and lots of time. It’s just not feasible when building large devices to build multiple physical prototypes, which is why it’s essential for us to incorporate Ansys simulation and virtual prototyping into our development and design processes.”

Beyond its strides with filterless technology in industrial markets, the company has also used Ansys simulation to develop the HIVE air purifier for smaller spaces. The HIVE uses an advanced tablet-based activated carbon filter and a recyclable high-efficiency particulate air (HEPA) filter, ensuring complete reuse without the disposal of unsustainable materials. HEPA filtration was instrumental during the COVID-19 pandemic and continues to be a vital tool in mitigating airborne bacteria. For the HIVE, Praan used Ansys simulation solutions to understand fan requirements and develop specifications in two weeks, rather than the estimated four months it would have taken without simulation.

Walt Hearn, vice president of worldwide sales and customer excellence, Ansys, said, “Ansys is committed to sustainability, and we are grateful that Ansys’ simulation solutions have enabled Praan to contribute to the global clean-air mission. By developing advanced air purification technology for small and large spaces, Praan is helping to improve air quality in a wide range of environments around the world.”
