Increased Safety of Face Masks with Nanofibers

NanoLayr is the world’s leading manufacturer of high-tech nanofiber media, delivering high-quality to face mask manufacturers, such as Halo in the United States, and filter media for HVAC systems. To enhance the development and performance of its filtration media, NanoLayr recently invested in a new testing solution: the respiratory mask filter test rig Palas® PMFT 1000. Now, with the advanced Palas® aerosol measurement technology, NanoLayr introduced the SETA filtration media, which is a game changer in air filtration.

Palas® Upgrades Nanofiber Performance for Global Health

To enhance the development and performance of its nanofiber filtration media, NanoLayr headquartered in Auckland, New Zealand  worked together with the global aerosol expert Palas®. Nanofiber refers to a linear material with a diameter of nanoscale and a large length with a certain length-to-diameter ratio. The diameters of the nanofiber ranges from 10-300 nanometers, which is 10-100 times smaller than conventional melt-blown microfibers, meaning they are very effective in protecting against viruses. NanoLayr’s  nanofiber filtration material captures 99% of fine particles such as spores, allergens such as COVID, bacteria and other toxic particles.


As a leader in measuring and monitoring particles, Palas® provided NanoLayr different measurement solutions with its technical advantages. The Palas® PMFT 1000 test tig analyzes mask filter particles, bacteria and viruses, while giving NanoLayr the opportunity to immediately test its filters according to the required global standards, rather than sending materials abroad for testing.  With the help of the PMFT 1000, the preparation process for NanoLayr’s  products to market was rapidly shortened.


“The test rig is key to advancing the performance of our SETA nanofiber filter media product which is used in face masks that meet and exceed N95 and N99 standards,” says Ray Connor, CEO of NanoLayr. “It enables us to test the masks to ensure they meet required standards and properly protect people and health workers who are on the frontline of the pandemic in New Zealand and around the world.” NanoLayr’s SETA nanofiber is used by face mask and air filter manufacturers to produce premium products. It is a revolutionary approach to air filtration. The advanced technology provided by Palas® has helped to achieve this technological innovation. NanoLayr invests a lot to improve its products by increasing the performance of its nanofiber filtration media. As part of this, researchers from NanoLayr compared the performance of their SETA to traditional filtration media using PMFT 1000 and gained specific data which they never had before.
