ABSTRACT:
A scuba mask purging apparatus and method providing selective introduction of pressurized air into a scuba mask to initiate purging, pressure balancing, and de-fogging. An inlet valve, typically positioned conveniently on the top or the side of the mask may control the release of pressurized air into the mask. A pressure-sensitive outlet valve releases the pressurized air to force water from the mask. The outlet valve may be positioned on the lower portion of the mask or at a location where water is likely to collect.
