Advertised as comparable to Pentek R50-BB. Pentek R50 50 microns but they say 5 microns. I wanted them for a pre-filter that doesn't clog easily. But the micron ratings on all these "fake" are highly suspect as there are no certificates from testing labs. It also begs the question of what quality control is applied in terms of hygiene when building these drinking water filters. Cheaper yes, but what is your health worth to you?
