Haven't changed air filter in Honda Accord (1996) for 4 years, but it's barely dirty?

what does that mean? shouldn't it be extremely dirty? thanks

Its all depends on the climate you live in. In a city you will have less dirt but gravel road driving I change mine every year. Honda Accords also don't suck that much air. If it isn't dirty don't change it. On the other hand, an air filter is cheap. If it makes you feel better change it and don't worry about it.

Might also be a good idea to check and make shure that all the seams on your air box are tight.

it may look clean but after 4 years if you do any driving at all change it . air filters catch a lot of fine dust and dirt particles so just because it doesn't look dirty your car can have a hard time breathing through it
If you have been driving it regularly then yes.
Did you check both sides of the Air Filter? Also, take it and hold it up to a light bulb, and if you cannot see the light through it, even if it looks clean then it is clogged. You should be able to see light through a clean filter.

4 years, you should change it just on principle.
