Innovation
Sustainable low-carbon alternative to activated carbon filters, Purenat technology is the first activated filter that permanently destroys VOCs and micro-organisms, and therefore doesn’t clog up. Pressure losses are considerably reduced, minimizing energy consumption. Its longer lifespan reduces waste production and maintenance costs, offering a competitive advantage that addresses both environmental and economic issues.
Purenat’s innovative material adresses customers’ growing needs by improving air pollution control efficiency, without releasing secondary pollutants, and by offering the possibility of optimizing product design to reduce weight and costs. Purenat is the only solution that addresses all three areas of improvement.
The innovative material developed by Natacha Kinadjian Caplat takes the form of a thread, which is then transformed into a textile using the non-woven process. The composition of this thread contains an active depolluting agent (photocatalytic agent) that destroys organic pollutants. This is the first time that a thread, then a filter, is composed of such an active agent, rather than simply being coated. This major technological advance overcomes the current shortcomings of photocatalysis: no loss of efficiency, no release of hazardous nanoparticles, no generation of dangerous by-products. All this with the added bonus of a flexible, lightweight material for easy plug-in into air treatment units.
Purenat thread, the origin of active filter media, was developed on the basis of what occurs naturally in the living world. Its three-dimensional structure mimics the alveoli of diatoms, marine algae. The result is a perfect balance, never achieved before, that maximizes exchanges between the air and the active purifying material, boosting efficiency.
Our major technological advances have led to the award of a patent. This patent is testimony to our unique expertise in the field of materials and Indoor Air Quality (IAQ). It confirms the value of our air pollution control technology. It strengthens our position by enabling us to offer exclusive, differentiating solutions to our customers. It reflects our ongoing commitment to research, innovation and the creation of high value-added products.
Optimization of Photocatalysis
The core technology, reinvented by Purenat, is that of photocatalysis. It allows for the transformation of organic pollutants into minute quantities of carbon dioxide (CO2) and water vapor. The efficacy of this process in eliminating pollutants has been demonstrated by numerous publications and is widely recognized within the scientific community. Purenat revolutionizes photocatalysis with an active textile that maintains its effectiveness over time and produces no hazardous by-products or releases.

Founder & President
As a Doctor in Physico-Chemistry of Materials, she is a specialist in Indoor Air Quality (IAQ) with over 14 years of experience. Her passion for IAQ began during her thesis in 2010, where she developed materials for air purification. It was during this time that she became acutely aware of the crucial importance of IAQ as a public health issue.

Applications
An integrable technology tailored to meet the air pollution challenges of industrial and manufacturing companies across multiple sectors.
Winner of the Pollutec Innovation Awards 2023 and the Global Industrie Awards 2023 in the “Start-Up” category.
Thanks to its advanced technology, Purenat effectively eliminates volatile organic compounds (VOCs) and odors, which are serious hazards to human health and the environment. Purenat is attentive to the needs of industries aiming to reduce external emissions and improve air quality in their factories. This approach addresses tightening regulations, preserves workers’ health, and meets the ambitious carbon neutrality goals affecting the sector. Implementing a custom pilot project will provide the most suitable personalized solution to meet each industry’s needs: pollutant reduction, energy and maintenance cost savings.
Winner of the Pollutec Innovation Awards 2023 and the Global Industrie Awards 2023 in the “Start-Up” category, Purenat protects operator health and limits external emissions with its ability to destroy VOCs and odors, which are responsible for many illnesses. Purenat supports industries in their air depollution projects to meet increasingly stringent regulations, offering a comprehensive solution: from the initial problem analysis to the installation of custom-sized depolluting cartridges.
Wastewater treatment plants face various air pollution challenges, including emissions of odor-causing compounds and greenhouse gases. The Purenat solution, with its innovative active depolluting textile, effectively destroys pollutants and VOCs, thereby reducing odor nuisances. Whether extending the lifespan of biofilters, replacing the current solution, or reducing maintenance costs, conducting a Purenat pilot project allows for the installation of a suitable and customized solution. Additionally, this technology ensures regulatory compliance and enhances the economic performance of wastewater treatment plants.
Purenat’s active textile can be integrated into building air ventilation systems. By destroying pollutants rather than merely trapping them, there is no longer a need to replace filters every six months as is currently required. This significantly extends filter lifespan, reducing maintenance efforts and associated costs. Additionally, a filter that does not clog leads to decreased energy consumption. Studies have shown that in commercial buildings, 30% of energy consumption is attributable to filter clogging
Purenat’s active textile is a lighter, more durable, low-carbon, energy-efficient, and less wasteful solution compared to the filters used in current ventilation systems. Purenat addresses the challenges of decarbonization, weight reduction, maintenance simplification, and multi-level air treatment in various modes of transportation: airplanes, trains, cars, and ships.
Purenat is responsive to defense sector stakeholders, addressing issues of sovereignty, space efficiency, lightweight design, and effective pollutant neutralization at multiple levels: in submarines, vehicles, and infrastructure.
