NWI Expands Its Filtration Testing Capabilities

NWI has expanded its analytical capabilities and is offering services for testing and validation of filter media.  The additions include a new laboratory dedicated to testing masks and respirators.

The new ASTM standard (F3502-21) released recently is a welcome addition.  Over the last year, we have seen an incredible amount of misinformation regarding the efficacy of masks and other PPE, and to date, that continues.  The new ASTM standard defines various levels of performance, but most importantly, the labeling requirements are intended to inform the consumer regarding the performance of the masks they are purchasing.  There is also the option of offering reusable masks that can be laundered and/or decontaminated and the performance must be performed by competent laboratories accredited to ISO/IEC 17025, and the testing performed must be within the scope of the laboratory’s ISO/IEC 17025 accreditation.

NWI’s facilities are equipped with TSI 3160, TSI 8130A, Palas MFP3,000, conditioning chambers, TSI PortaCount as well as prototyping capabilities so that various forms of masks can be produced from various layers of nonwovens and tested as a system.
