I have these Pentair filters that I'm thinking I need to replace. I don't know how old they are or how often they need replacement, but I think the previous owner probably never swapped them out in their entire lives.
I see a bunch of different P/N's on them, but I don't know which I have. I'm guess they are the P/N that is set aside by itself, the 130 Sq. Ft. ones. Am I right? Here they are. Also, what is a good vaccuum thing to get? As of now I've been stealing my dads every couple weeks.
