Which 3M PPE factory folded?

Cursory searching says in 2020 they created a new production line in Wisconsin and moved it to 3M Aberdeen.[1][2]

If you look on Google street view dates for the Aberdeen factory and compare 2019 to 2023 it had a big expansion that's still there.

The other major 3M PPE factory, 3M Valley, was expanded in 2024. [3]

Edit: For the curious, Honeywell did fire their pandemic mask factory workers, closed a pandemic mask factory, and then exited the PPE business entirely. [4][5][6]
