The W203 filter locations are on pages 7 & 8 of http://www.buellwinkle.com/HVAC-W203.pdf
It includes other esoteric information for the technically curious...
Recently replaced the (2) interior charcoal filters (# 203 830 21 18) during the course of a DIY service B. Incidentally, M-B recommends their replacement only after 60k miles or 5 years. Didn’t notice any difference, except for a wallet that was ~$100 lighter.

I am in the process of changing filter and wanted to make sure the quantity of filter that I have.
2003 C230 sedan, 1 filter on top of battery, right?

Anytime. It’s always better to bump an existing thread IMO.
Looks like I scared KYC32 away two years ago. :nix:
You definitely have the one above the battery.
Only those W203’s with the Automatic Climate Control HVAC system utilize the under-glovebox filters.
nlpamg put together an excellent tutorial… https://mbworld.org/forums/c-class-w...placement.html
