New Filter Retainer Assembly — Takes either chemical cartridges or flat disc of chemically treated felt. New Face Piece —- Non-leaking, snug fitting, comfortable, of durable, pure rubber. Increased Visual Area — New slender cartridge design and lower location of cartridge afford wider field of vision. New Flexible Fitting Brace — Face piece adapts to features of wearer by slightest hand pressure on brace for perfect fit. Headband pressure cannot pull pliable rubber face piece out of shape.
