Chicago Flag Face Mask with Built in Filter or Filter Pocket by Neosho Art
Built In Filter:
Provides three layers of protection; outer layers 100% cotton and inner lining is non-woven polypropylene fabric to improve filtration. Masks are breathable and washable; hand wash with soap and water and lay flat to dry.
Filter Pocket:
Filters for these pocket masks are blue shop towels. These towels are made from a polyester hydro knit and have been shown to be ideal for particle filtration. Sellars Tool Box and ZEP's Industrial Blue Towel are most effective. Dried out unscented baby wipes also work well for filtration. Cut and insert a layer of shop towel inside the opening on the bottom of the mask. Dispose of filters after use. Hand wash mask and lay flat to dry.
For every mask sold, Neosho donates another to frontline or essential workers in Chicago.
