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.

Breathing mask

A deformable, pad-type filter is provided which does not have a frame but instead uses two filter elements, at least one having a non-planar configuration in a stress-free condition, which are preferably joined along an outer edge to form an inner chamber. A connector is located in and attached to one of the filter elements, the connector having a rigid connector platform which projects radially outward from the connector to enable a user's fingers to grasp the perimeter of the connector platform to twist or otherwise manipulate the filter for connection or disconnection to a respirator facepiece without damage to the filter material.
