This should be an easy one.. I already have an opinion on this but
would like to hear more as I could be wrong (not being a air flow
expert and stuff).

When deciding between going with an electronic filter vs filter media
(assuming cost isn't an issue) which would be better. I've seen how
electronic filters are built and I would think that they provide less
restriction. However, I've been told the opposite - that filter media
provides less restriction than electronic filters... Is that true?
