Protek Nano A99 Face Masks

Our Techonlogy

The Protek Nano Nanofiber Face Masks offer next generation filter performance designed for commercial, industrial, and general consumer use.

They are designed to be worn for up to 24 hours before disposal - saving costs, increasing worker efficiency, and reducing environmental waste.

The innovation of the A99 mask is in the replacement of the traditional "meltblown polypropylene filter" with a proprietary nanofiber membrane designed to firstly capture both large droplets and tiny contaminants and then deactivate bacterial and viral microbes through lipid envelop disintegration and protein denaturation.

Each nanofiber is functionalized during the electrospinning process - no external treatments are applied to the membrane.

The filtration efficiency of the nanofiber membrane is maintained over an extended time period, even when wet, due to the high specific surface area (>500 m2/g) achieved during the electrospinning process and does not rely on electrostatic charge for filter performance, as do traditional meltblown filters, which dissipates over time and when wet.

The Protek Nano A99 Face Masks achieve bacterial filtration efficiency (BFE) and particle filtration efficiency (PFE) of >99% to exceed the standards of conventional N95, KF94 and P2 Respirators as well as meeting AS1716:2012 and AS4381:2015 standards. The mask design also meets CDC recommendations to seal around the face without gaps to block the entry of unfiltered air.
