They seem to work (and this was recommended by the installer of our whole house quantum disinfection system) because we need to clean our water collection tank, so this is probably overloading our micron filters a bit , but before we do this and ours When we last replaced another micron filter, our water pressure got worse every day, but when we changed the filters, the pressure was perfect. And then, three days after we had to change the filter again (so today), two or three months later, whatever it was, the water pressure started to suffer again! Then after the replacement everything is fine. That's proof enough for me that he's doing his job.
