The present invention provides different size breathing masks in which single size filtration shells are attached to a single size face contacting member at the same periphery. A single size face contacting member has one, or more than one size, inner breathing opening with a narrower cut profile in the nose area than in the mouth and chin area. Such different size breathing masks would fit and provide an effective seal for more than one size of wearer.
