Are Berkey water filters NSF certified?

I couldn't find anything on their site about this. Anyone know?

My understanding is that they exceed it.

Black Berkey® Purifier Elements are the world's most powerful gravity filtering solution, certified to eliminate pathogenic bacteria to the EPA's "7 Log" purification standard of 99.99999% reduction. Elements are easily cleanable with a Scotch Brite® pad under running water, and each element will purify up to 3000 gallons of water (6000 gallons per set of two.) The Black Berkey® filter formulation has been tested by State & EPA accredited laboratories to exceed EPA & ANSI/NSF (Std. 53) protocol.
