• This innovative mask was designed to eliminate all stitching and incorporates an outer layer of spandex for comfort and seal conformance to the face.
• The layers of filtration are adjustable since the entire mask can be dismantled for cleaning and adjustment by sliding the aluminum nose piece out.
• Supplied with 2 layers of cotton pillow material for high filtration rates but this can be reduced to one layer for comfort if desired.
• Filti material (4 pieces) are included in the package. Filti material traps 95% of particles down to 0.3 microns (about 150th of the thickness of human hair).
• Additional Filti pieces can be purchased from Signature Art Ware. 
• Different sizes for comfort and optimum sealing - please see size selection chart. Measurement is from tip of nose to the Tragus (lump in front of the ear). Please see photo for clarification if needed.
• The mask does not extend under the chin and this reduces shifting during talking. 
• Spandex ribbon included to adjust fit and allow ability to rest the mask around the neck if desired. 
• Manufactured in McMurray PA with all USA materials.
• Price includes first class mail shipping. Please note that there is no tracking on first class mail.
• Please note that this mask is not intended to be used as a substitute for a medical / surgical mask. 

Size selection in inches - please not that this is a general guide and unique individual features may need a size larger or smaller.
