I don't believe the bad reviews about this filter. I believe it was written by Calligan! Example: How can a filter contaminate water? Crazy. 25 microns seems spot on. They don't limit the pressure at all. 5 micron filters load too quickly. If you want a good sediment filter with some flavor boost this seems like a good choice. I've been a builder for a long time and have tried a lot. Of course, others work well too, but again, 25 microns is spot on.
