AC Cabin filter
 

Here we gonna face 55+ C in SA.

Can I drive my car without Cabin filter?

Any harm to the vehicle?

will appreciate your replies.

y you dont want to have filter. just buy one and install it. over time it will surely be bad for passengers and debris that will accumulate inside.

Yep, and you will build up crud on your evaporator, leading to corrosion and an early death of the part. A difficult and expensive repair.
