the difference between the old ones and the new ones.

Do you check air filter in your car? Likewise see it against light or
sun.

Filter"s" (plural)

I wonder how many people don't even know that there is a cabin air filter in their car.

I have bought 4 used cars in the past three years (3 in the past 12 months) and everyone of them had a fairly clean engine compartment filter but a cabin filter that was black and filled with leaves, bees and other debris.

Partly because they don't know it is there and partly because it
is very hard to replace. Mine is coming up for replacement and
it is a hassle. In my car I have to pull the glove box out of
the dash to get the filter out of its holder. Whenever I get the
oil changed they always show me a really bad cabin filter and
ask if I want to replace mine. I know the one they show me is
not the one out of my car, because they wouldn't pull it out
and I don't figure it is as bad as the one they show me. At
least it wasn't the last time I replaced it. They don't say that
it is my filter, they just suggest replacing it.
