Not necessarily.....it's a filter, and well....whatever happens to get trapped and pooled in there, basically turns into a Petri Dish
You'll have bugs, leaves, moisture, etc.....all in there....stuck, and breeding all sorts of crazy bacteria....
Now, fast forward 5-10 years.....on the same filter.....the dirt and debris keeps multiplying

Now, if you're one to lease a vehicle, or not keep it for very long, sure, don't replace it
But us who keep our cars for life (or until the inevitable happens) it's a good maintenance item to change out regularly
Kinda curious though, the cabin filters are a relatively "new" feature, I believe they started in the mid to late 90s on vehicles.....I know my 88 Aries does not have a cabin filter for example
In a way, this almost sounds like an added expense that the car manufacturers add just to keep you coming back for yet another filter
I'm curious though, my car doesn't have a filter.....where does all that gunk that a filter would be trapping, go? lol....
BTW, anyone catch some of the latest adverts? I think I actually started hearing them this past year, a number of manufacturers (think Nissan, or Hyundai.....) contains "air scrubbers" which are supposed to purify the air......works similar to that of an "Ionic Breeze".....though I believe they still have cabin air filters as well, it's just another line of defense to "cleaner air" hehe.
