Haze Season and Cabin Filter Importance
Malaysia experiences annual haze events (typically June–October) when PM2.5 particle levels spike. A clean activated-carbon cabin filter in your 4 Series absorbs these particles before they enter the cabin. With a clogged filter, the blower motor works harder and A/C cooling efficiency drops noticeably. The European recommendation of 30,000 km cabin filter replacement is too long for Malaysia — at 4M Car Care we replace it every 15,000–20,000 km and check condition at every oil change.
