25 micron A.O. Smith filter
It works I filter the water coming in the house. I filter my drinking water out of my refrigerator. The last one was visually brown i assume iron oxide so i replaced it. So far so good it's a 25 micron so a ok.

It’s alright!
I don’t know if it was our water system or these filters but I feel like they got way dirtier than they should have, either way they did their job!

QUALITY FILTER
I always use this product in my whole house filter system and change it faithfully every 4 months to prevent any sediment from the town water getting into my water softener. Believe me, it makes a big difference.
