I'm surprised that the "Best Solution" is posted as a long process of removing weather stripping, wiper fluid hoses and removing screws. All you really have to do is open the glove compartment, pull the access panel in the back, and open the door that says "air filter access", then pull out the 2 filters.
Not sure about the arrows, but on my 2005 Terraza, the cabin air filter is easily accessible from the interior of the glove compartment.

The cabin air filter for your 2002 Buick Century is located under the
cowl in the firewall between the engine compartment and the passenger
side of the front seat. To change the filter:
1. Leave the wipers in up position.
2. Open the hood
3. Remove the weather stripping from passenger side of cowl
4. Unclip the window washer line (two or three places)
5. Remove the three fasteners with an ordinary screwdriver (one is easy, the other two were more difficult)
6. Take out the cowel cover
7. Remove old filter
8. Put in new filter
9. Replace cover, fasteners, washer line, and weather stripping.
Do it about every 20,000 km. I left mine for nearly 130,000 km and it was filthy dirty.
New filter costs about $12

When installing cabin air filter, in 2005 Buick Terraza, does the arrow on the filter point up or down?
