Restriction has nothing to do with filtration. You can properly filter with a lower restriction when using a better material.

I fully understand dirt holding capacity - no one is stating not to properly maintain a reusable filter. But you're contradicting yourself - which is it, do they not filter as efficiently or do they load up with dirt?

No Kool-Aid here....just simple real world testing over the past 20 years. I've long given up attempting to argue with keyboard commandos - life is too short. If you're fine in your opinion that's great. Have a great day.
