The filtration mechanism of the mask allows it to filter out “99.9% of particles that are up to 0.075 micrometre in size”. This works out to be 75 nanometre which is much smaller than the 200–500 nanometre diameter of the Covid-19 virus particle.
Catalist-listed Malaysian garment producer KTMG last month launched its own direct-to-consumer brand XCF and an $18 filtration face mask as its flagship product.
Unlike disposable masks that do not give much protection, KTMG’s mask has built-in proprietary technology that makes it comparable to the N95 face mask typically used by medical professionals.
