99.9% FILTRATION EFFICIENCY NANOFIBER MEMBRANE
There are currently no specially developed masks to protect against viruses, but existing masks are dust masks that are used for worker safety purposes and provide protective effects on airborne particles known to everyone as N95 masks. The N95 is one of the most common face mask filter standards published by NIOSH (National Institute for Occupational Safety and Health). The equivalent of this in European countries is EN149 standard; Although the N95 performance class masks do not have the exact equivalent in this standard, they are somewhere between FFP2 and FFP3. At the same time, surgical masks used in hospitals, surgical operations are a completely different product class than N95 and equivalent respirator-type masks, protecting the operating environment from contamination by blocking the particulate saliva or respiratory secretions that will spread to the environment by the wearer. However, the surgical masks also protect the wearer to a certain extent from aerosols or bioaerosols in the air.
When all these experiences are evaluated, it becomes necessary to develop a face mask that will provide the necessary protection against viral risks and which is comfortable enough for daily use. At this point, the application of nanofiber technology, which offers unique solutions in many different application areas including filtration, comes to mind as a solution based on solid scientific data.
Nanofibers can tremendously improve the performance of filter media’s ability to remove particulates from air streams. Nanofibers could be the key elements for filter materials in face masks or respirators. They have a very high surface area per unit mass that enhances capture efficiency and other surface area-dependent phenomena that may be engineered into the fiber surfaces (such as catalysis or ion exchange).

The filtration media is produced using a patented novel technology “Hybrid Electrospinning”.
Replacing Meltblown Materials
The structure of nanofiber media makes them a unique material for fine dust particles, aerosols, bacterias or viruses. Nanofiber based filters provide better filtration performance than conventional meltblown materials with a quite smaller weight per basis area.
The nanofiber membranes are considered to be the next generation filtration media, due to their high efficiency. Large corporates are looking into incorporating them in their products range.
In 2017, our project titled “Development of Improved Nanofiber Based Facial Mask with Functional Nano Particle” was supported by TÜBİTAK. During the project, mask production trials were carried out with many different materials and the samples providing the highest performance were converted into products. All these studies were carried out by electrospinning devices manufactured by our company.
Electrospinning technology is the most efficient method for commercial production of nanofibers and İnovenso is one of the leading companies operating in this field. Established in 2010 with the support of the Ministry of Industry, our machines are today in more than thirty countries. Export rates are around 90% of total
