Dimensions of our face masks are as follows-
Standard: 4" x 6.75"
Large: 4.25" x 8.5"
Each mask contains our proprietary skin-friendly fabric on both sides, a BFE95* filter in between and an adjustable thin metal nose band for best fit. Elastic ear attachments are on either side.
*BFE95 (bacterial filtration efficiency) means that 95% of particles sized 1.0-5.0 microns are filtered out. This type of mask is suitable for use in environments where low amounts of fluid, spray and/or aerosols are present.
