Rust on filter can

[JHZR2]

I pulled an older Hengst filter I had in stock, for my MB300cd. These filters have a full flow and a bypass section.

The bypass section flows from the inside-out through small louvered holes. Some of those holes had rust residue (raised rust) around them. I figure that can shed particles, and thus condemns the filter.

Any opinion on seeing rust on a filter? Would you use?

Not at my current location. Already installed an MB filter, so it’s as much recycle or use in the future, as anything.
