The PCX is still made by Toyo Ruki of Japan, as is the tiny Insight filter.

The standard PLM is contracted out to Fram/Honeywell. I've seen them with a third brand name that I can't recall, however all the current ones will be marked "Fram" or "Honeywell." Odd, because Fram and Honeywell is the same company.
