REPLACEMENT INTERVAL
Since the cabin filter has a limited service life, it is important to replace cabin filter on a regular basis. After a certain time cabin filter is saturated, i.e. it cannot absorb more particles, and it ceases to function. Vehicle manufacturers have stated one year or about 15,000 km as a guideline for functional performance.
If the maximum pollutant absorption capacity has been achieved, the normal flow of fresh air is obstructed, because the air flow is greatly reduced. Despite running the blower at high settings, the windows fog up and streaks form.
 Compare between new and used filterThe lack of fresh air causes the occupants to become more tired, causes health hazards, and increasing the risk of an accident.
The lower flow of air also poses difficulties for the blower, because it must work against the higher resistance of the clogged filter.
A filter saturated with dust and other contaminants also leads to an unpleasant, mildewed smell in the vehicles interior and is an ideal breeding ground for microorganisms such as bacteria and molds.
If the cabin filter is damaged, the condenser gets contaminated to a greater degree, reducing the cooling efficiency of the air conditioner and possibly leading its failure. The consequence of this is higher repair costs.
Furthermore, bacterial and mold pass unhindered through the blower to the passenger compartment and create a health hazard for its occupants. The seats and interior lining also become disproportionately dirty as a result.
