Unique solution that uses nanofiber technology to destroy airborne pollutants and pathogens
Purenat is a French deeptech company pioneering a new generation of active air-purifying textiles for industrial environments. Based in Bayonne, Purenat has developed a patented biomimetic and photocatalytic technology that doesn’t just trap pollutants, it destroys them.
By integrating photocatalytic particles directly into the fiber, Purenat’s textile neutralizes volatile organic compounds (VOCs), bacteria, and viruses, transforming them into harmless molecules. The result is a durable, recyclable, and energy-efficient air purification solution that combines high performance with sustainability.
Objective
Purenat’s goal is to become a European reference in sustainable industrial air treatment. The company aims to move from prototype to large-scale industrial production, making its innovative textile available to integrators, manufacturers, and end users across Europe.
Through strong partnerships with industry leaders such as Clauger and Big Dutchman, Purenat seeks to validate its technology on-site, standardize its production process, and accelerate the adoption of low-carbon, energy-efficient air purification systems.
Proposed solution
Purenat offers a patented active depollution textile that can be integrated into existing or new industrial ventilation systems.
Its main features include:
- Active depollution through photocatalysis: pollutants are broken down, not stored.
- Biomimetic structure inspired by marine diatoms, maximizing surface exchange and efficiency.
- Durable and safe materials: no nanoparticle release, fully recyclable fibers.
- Plug-and-play integration: compatible with a wide range of industrial setups, minimizing installation costs.
- Lower operating costs: reduced energy consumption and longer filter lifespan compared to conventional systems.
This innovation allows industries to improve air quality and meet environmental standards without compromising operational efficiency.
Who is the proposed solution for?
Purenat’s technology is designed for industries where air quality, safety, and emission control are essential:
- Manufacturing and surface treatment industries, to reduce VOC emissions and odors.
- Food and beverage production, ensuring contaminant-free environments.
- Waste management and recycling plants, for cleaner and safer working conditions.
- HVAC system manufacturers and air-treatment integrators, looking to incorporate active, sustainable filtration into their systems.
By offering an effective, scalable, and eco-friendly solution, Purenat helps companies transition toward cleaner, more sustainable industrial operations.
