Gee, I never thought of that!!! ;-) And of the Google returns, which one should I choose? They all look different with no hole cut in the center...
Edit: well I heard back from Rod and he says the number shown is the replacement filter. OK... I'll order one and see what I get. The pics sure look different WRT the hole for the air to bypass the filter media.
