ViewTop Criticism
+10 pts“I live in an area with tough water sources and everyone I’ve ever known that used a BeFree clogged their filter and had it die a very early death. I would never buy any filter you could not back flush. I think they’re shitty but just my opinion based on the four or so I’ve seen fail.”
