PMM speaks with UFI Filters, a leading company in filtration and thermal management, to find out its top tips for the proper replacement of cabin air filters.
In order to protect against harmful particles and boost the efficiency of the air conditioning system, UFI Filters recommends replacing the air cabin filter regularly: every 15,000km – even at shorter intervals in particularly dusty areas – or at the latest, every six to 12 months. This operation is crucial for guaranteeing health and comfort inside the vehicle.
The company also advises that the selected filter corresponds to the application suggested in the catalogue – the use of incorrect part numbers is a frequent cause of malfunction, and may even result in the collapse of the filter. Garages should follow service procedures as suggested by the vehicle and filter element manufacturer in order to achieve the best possible service operations and prevent functionality issues.
Common fitment errors
- The filter cannot be located, with the disassembly/assembly procedure only partially understood
- Residue in the filter housing is not removed and the housing is not properly cleaned – if necessary, use an antibacterial spray
- The replaced filter is not perfectly sealed in its housing, e.g. as the new filter is not the same as the one being replaced
- Noises or leaks are not identified after replacement
Dangerous knock-on effect
The poor fitment of a cabin air filter, or failure to replace it at the recommended intervals, can lead to a number of dangerous risks:
- An accumulation of harmful gases, unpleasant odours and airborne particulate matter that trigger allergies, throat discomfort or sneezing
- Fatigue and poor concentration after prolonged driving
- Poor visibility due to condensation that builds up on the windscreen and side windows
