PureAir Filtration, known for removing corrosive gases and toxic vapours, and Noble Biomaterials have developed an antimicrobial fibre, FiberShield, which can be used as an added fabric layer in particulate filters to help fight microbes amid the COVID-19 pandemic. Noble is a leader in antimicrobial and conductivity solutions for soft-surface applications.

FiberShield is made of a proprietary blend of nonwoven nano-fibres that are impregnated with antimicrobial Ionic+ silver technology. The antimicrobial fabric can be used in any particulate filter and is the only one on the market to offer such flexibility to filter manufacturers. FiberShield with Ionic+ technology has been tested and proven effective by independent testing laboratories to inactivate over 99 per cent of specific pathogens, according to a press release by PureAir.

PureAir also debuted a second product in its antimicrobial line called Microbe-sorb, an adsorbent media that utilises a proprietary blend of compounds to activate, enhance and deliver the strong antimicrobial properties of permanganate, a material commonly used in medical practices since the early 1800s. Independent laboratory tests show Microbe-sorb inactivates over 99 per cent of microbes on contact.

Both of PureAir’s new products are aimed at mitigating the impact of the COVID-19 pandemic by focusing on improving air quality through gas, odour, and pathogen removal.
