The Latest and Greatest: AFS Corporate Sponsor Product Spotlight on Antimicrobial Filter Media from PureAir Filtration

PureAir Filtration’s FiberShieldTM is a Nylon 6,6 nonwoven spunbond microfiber material impregnated with silver (Ag) ionic nanoparticles. The silver ionic mesh creates an antimicrobial Zone of Inhibition around and in between the fibers that deactivates viruses, bacteria and fungi. For example, FiberShield deactivates >99.89% of the SARS-CoV-2 (the virus that causes COVID-19).

FiberShieldTM has a basic weight of 34 g/m2 per layer and a pressure drop of 0.11 iwg (27 Pa). The thin and light substrate allows for more pleats in the same size filter housing, increased media surface area and dirt holding capacity, lower pressure drop, and smaller and lighter weight filters. The particle filtration capability is rated as MERV 4. The melting point of the fiber is 265oC, and its heat capacity is 1.47 J/g*K, with thermal stability that can withstand 150°C consistently.

FiberShieldTM is 100% Made in USA and satisfies the Buy American Act. Production capacity is over 4 million pounds annually.
