LydAir® MB filtration media for medical and surgical facemasks and N95 respirator masks uses a polypropylene construction to provide high filtration efficiency while minimizing airflow resistance.

LydAir® MB Filtration Media for N95 Respirator Masks is engineered for consistent processing in molded respirator applications and a multi-layer mask design. This material is available in white and has been flat-sheet tested to meet an equivalent rating* of NIOSH Efficiency Level N95 per TSI 8130.

LydAir® MB Filtration Media for Medical and Surgical Facemasks is engineered for consistent processing in stitched or ultrasonically sealed masks and serves as the filtration efficiency layer in a multi-layer mask design. This material is available in white and has been flat-sheet tested to meet an equivalent rating* of Bacterial Filtration Efficiency (BFE) 98 and 95 per ASTM F2101 and EN 14683 at a media face velocity of 12 cm/s. MB 1049HW is available as a standalone meltblown layer, or as CL 1049HW which is a collated product with a single polypropylene spunbond layer.

LydAir media is also available in microglass and in synthetic/glass and poly/cellulose composites. Material construction can be customized to suit individual applications and media properties. Please contact Lydall for more information.
