GIR Face Mask Filter Refill Pack (10 filters) SALE!

Product Description

This refill pack includes 10 filters and have the same technical filtration specifications as N95 masks.  These filters work with most double layer fabric mask that have a pocket.  If using with GIR silicone face masks click here to tricks on making the filter stick to the silicone.

Originally $10 per pack now $4.99 per pack!

  • GIR’s filters pass the following test standards, with specific results listed below: YY/T 0969-2013: BFE 99.7% filter efficiency GB/T 32610-2016: PFE 92.6% filter efficiency for 1 layer (we are using 2 electrostatic layers) GB2626: >95% at 0.3 microns
  • GIR filters are made from four layers of material: an outer spunbond nonwoven polypropylene layer to block initial large particles, dust, and liquid droplets. A double layer of very fine, electrostatically charged melt-blown nonwoven fabric to block finer dust particles, bacteria, and virus-carrying droplets, and an enclosing inner layer of spunbond polypropylene to block exhaled droplets.
  • Melt-blown fabrics are available in a variety of densities with different filtration efficacies. We require a >40g per square meter density for the double melt-blown fabric layer, which supports a PFE (Particle Filtration Efficiency) over 95% at 0.3 microns and a BFE (Bacterial Filtration Efficiency) over 99% for particles at 3.0 microns.
  • According to CDC guidance, SARS-CoV-2 (novel coronavirus) is thought to spread through person-to-person contact and through respiratory droplets. Though the size of the individual virus particle is about 0.1 microns, respiratory droplets are many times that diameter. Therefore, filtration efficiencies measured at 0.3μm PFE and 3.0μm BFE may provide acceptable protection against the spread of COVID-19. This statement has not been evaluated by the FDA, and is intended as a general statement about filtration efficiencies rather than a statement of efficacy regarding any specific filter.
  • Furthermore, it is reasonable to assume that appropriately tested multi-layer nonwoven filters and non-permeable platinum silicone will provide superior protection to non-medical cloth mask barriers that the CDC is currently recommending for public settings.
  • These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.
  • 10 filters per pack
