replace cabin air filter

Replacing a cabin air filter is a five‑minute job and a gift to your sinuses. Most cars hide it behind the glovebox; some stash it under the bonnet near the windscreen cowl. Drop the glovebox (squeeze the sides), pop the access cover, note the airflow arrow, then slide the old filter out like a regret. Slide the new one in the same orientation—arrows match airflow—and don’t fold the pleats like origami. The swap takes about 5–10 minutes and a filter costs roughly $20–$60. Do it every 15,000–20,000 km or yearly in dusty Aussie conditions, and more often if you cart pets or hay bales; if your car has a service reminder, reset it per the owner’s manual.
