## Indications for use
The SpectraShield 9500 Surgical Mask is a single use, disposable, surgical mask, tested for continuous use up to 8 hours, embedded with a zeolite carrier containing a silver-copper agent on the outer layer and is not an antimicrobial drug. SpectraShield 9500 kills 99.99% of test bacteria after one hour of contact with the surface of the respirator, and inactivates 99.99% of test influenza viruses after 5 minutes of contact with the surface of the mask. In vitro (laboratory) tests have demonstrated 99.99% kill on the surface of the outer layer of the respirator when tested in vitro against single isolates of the following test bacteria: Streptococcus pyogenes, MRSA (Methicillin Resistant Staphylococcus aureus), and Haemophilus influenzae, under tested contact conditions. In vitro tests have demonstrated 99.99% inactivation on the surface of the outer layer of the mask when tested against the following seasonal, pandemic, avian, swine and equine influenza viruses: Influenza A subtypes: H1N1 (A/California/04/2009, A/Brisbane/59/2007, A/Wisconsin/10/1998, A /Puerto Rico/8/1934), H3N2 (A/Wisconsin/67/2005, A/Brisbane/10/2007, A/Hong Kong/8/1968, A/Victoria/3/75), H2N2 ( A/2/Japan/305/1957); Avian Flu (bird flu) subtypes: Avian Influenza A (H5N1), Avian Influenza A (H9N2), Swine Flu subtype: H1N1 (A/Swine/1976/1931), Equine Flu subtypes: H3N8 (A/Equine/2/Miami/1963), Influenza B strains: B/Florida/4/2006, B/Brisbane/60/2008, B/Lee/40. No clinical studies have been conducted comparing the ability of an untreated surgical mask and the SpectraShield model 9500 surgical mask to protect the wearer from infection, and the antibacterial/anti-influenza virus treatment cannot affect pathogens that are inhaled around the edges of the respirator. The SpectraShield 9500 Surgical Mask is a single use device, intended for occupational use to protect against microorganisms, body fluids, and particulate material.
