Purolator lists their specs. So do Wix and Fram. Donaldson does, but it's hard to find. Baldwin, no. MC no. Ultimately, you will have to e-mail the prospective filter mfrs and ask directly, making sure you get the ISO4548-12 numbers, i.e. XX% @ XX micron. Most times they respond to direct questions.
