baldwin and fram side by side. baldwin on left and fram on right.
the frams media is smoother but baldwin has the pleats.
this is from their site about their filter:
"Baldwin uses two proven methods to separate and stabilize filter pleats.
PermaPleat® – an embossing process that builds dividers between pleats to prevent bunching and to ensure uniform airf low.
Beading – a continuous bead of adhesive around the circumference of the filter´s metal outer wrap, locking the pleat tips in place and preventing movement.
