Review on Highly Compatible 4 Block Activated Carbon 5 Micron Water Filters - Ideal for WFPFC8002, WFPFC9001, WHCF-WHWC, WHEF-WHWC, FXWTC, SCWH-5 by Lindsey Wright

They are a direct replacement for my whole house filter and are easy to assemble and install. I haven't had enough time on the filter yet to talk about filter life or efficiency. I changed it from 5 stars to 1 star. Do not use these filters around the house as they provide all filter flow. When I ordered 4, the first worked fine, the second worked fine for 3 weeks (expected 4) and then failed with an internal screen explosion. The third lasted less than a week before failing with an exploding internal screen.
