The time required to replace a car air conditioning filter typically ranges from 15 to 30 minutes, with the exact duration depending on the vehicle model design and the technician's proficiency. For most models, the filter is located behind the passenger-side glove compartment; the old filter can be removed and a new one installed by simply unscrewing a few bolts or unclipping fasteners. However, some luxury models may require disassembly of centre console components due to their complex structure, potentially extending the time to 45 minutes. For example, activated carbon filters can absorb odors but need to be replaced every 8 months, while HEPA filters are suitable for people with allergies but are more expensive, costing approximately 80 to 150 Malaysian Ringgit. If replacing the filter yourself, pay attention to the directional arrow mark on the filter; installing it in the reverse direction will reduce filtration efficiency. Professional repair shops usually charge a labor fee of 20 to 50 Malaysian Ringgit for replacement, which includes a basic air conditioning system inspection service.
