Review on Tier1 EP 20BB Micron Replacement: Cost-Effective & High-Quality Option by Brian Wolf

The first was a less expensive sump filter. When I sent it back they refunded me a lesser amount. The second one is 1/4" longer so the case can't be closed far enough to get a seal. It's returning too. I'm hoping to get the full amount back this time. I'll bite the bullet and buy this Original from Pentek It really wasn't worth the hassle!
