You can clear your mask "on the fly" while swimming in a horizontal position. "Also very easy with no purge."
I should not have implied otherwise. Those who oppose purge valves are correct in that:
There is no necessity for a purge valve. They correct a problem that does not exist. It creates a failure point. An inability to clear a standard mask indicates a lack of basic skills.
That being said, I will fly in the face of all that is right and good and proclaim that I still like my purge valve masks. I've only had one instance of a valve leaking and that was when a blade of grass got caught under the flapper. But, the front cover can be pulled off so the problem was quickly corrected.

I have heard that exhailing though the nose with a purge
mask while descending can cause just enough pressure to
equalize the ears, hands free.
