cabin pollen filter

Just when it is time for me to change the cabin pollen filter of my 2002
Accord, I am wondering if having a pollen filter really necessary. I
usually drive with my sunroof open anyways. I am just thinking of replacing
the filter elements with a furnace filter material just to filter off dust.
This would be a $40 savings up in Canada. Airflow would also be better.
Any opinion?

 

Just get in there and yank it out, and leave it.

We drove for many, many years and billions of miles without them. No
harm. They're just a checkmark on a marketing person's list--"look, we
have that too".

 

could just leave the filter out. older cars have no filter at all and
heat/cool just fine.

 

If you're sensitive and have allergies, by all means change the filter.
But if you're prone to driving with the roof open, as they say in
Jersey, fohgetabou'it.

 

I would be concerned that if you just leave the filter in (and use the
ac or heater) it would eventually get clogged. Could be a lot of hard
work on the motor and the evaporator coils might not get enough air flow.

As long as there is decent air flow, no real worry though.
