Abstract
A component is attached to filtration material by providing the component with a deformable extension member that is preferably integral with the component and that extends from a base portion of the component. The extension member is inserted through an opening provided through the filtration material and is then deformed to provide a mechanical clamp that is utilized in attaching the component in position. In certain embodiments, the component is an attachment such as an exhalation valve of a respiratory mask.
