Respirator filter |
摘要 |
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.
