Brezza AC filter at 30k km, is that too long for Bengaluru dust?

Saw this on mycarhelpline, the Brezza service schedule lists AC filter element replacement at 30,000 km and again at 60,000. That feels long for ORR and Hosur road dust. My cooling still feels okay at my current odo but I keep wondering if it is quietly clogging before the scheduled mark. Anyone here got it checked or swapped earlier than 30k, and did cooling actually improve or was it just placebo and rupees gone.
