New Filter Retainer Assembly — T a k e s either chemical cartridges or flat discs of chemically treated felt. New Face Piece — Non-leaking, snug fitting, comfortable, of durable, natural rubber. Superior 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.
