Abstract
The present invention provides an improved filter connection system for a gas mask, comprising: a filter, a mounting means that attaches the filter to the gas mask, and a retainer means to hold the filter within the mounting means. The mounting means includes a protruding means; a valving assembly in communication with the protruding means, wherein the valving assembly enables air to flow from the fitter to the mask when the retainer means retains the protruding means, and disables air flow from the filter to the mask when the protruding means disengages from the retainer means; and a sealing means located within or adjacent to the valving assembly to prevent air from outside of the filter from entering the mounting means.
