Many drivers have already encountered a sudden deterioration in the efficiency of the heating or air conditioning, which often leads to a constant fogging of the windshield. The first suspicion usually falls on a compressor failure or a refrigerant leak, the repair of which tends to be expensive. In many cases, however, the cause is much simpler – it can be a clogged cabin filter.
- A clogged cabin filter can reduce the efficiency of the air conditioning and heating.
- A dirty filter allows allergens to enter the car cabin.
- Moisture and dirt in a clogged filter encourage the growth of bacteria and mold.
- Regular replacement extends the life of the ventilation system and reduces fuel consumption.
The main task of the cabin filter is to clean the air flowing into the interior and protect the crew from dust, pollen, exhaust gases or other impurities. But if it becomes clogged, it stops fulfilling its function, which can cause various problems. A musty and unpleasant smell that spreads through the interior after turning on the ventilation is often the first warning that something is wrong.
Neglecting to replace the cabin filter regularly can seriously endanger the health of passengers. The moisture and impurities that are trapped in it create ideal conditions for the reproduction of bacteria, molds and fungi.

An even bigger problem is the fact that a clogged filter can no longer effectively capture allergens. Dust and pollen thus freely penetrate into the cabin, causing irritation of the respiratory tract, sneezing, coughing and watery eyes. Driving in such conditions reduces the driver’s concentration, which increases the risk of an accident.
A dirty cabin filter affects not only health, but also the performance of the ventilation system. Limited air flow forces the fan to work more intensively, which leads to its overheating, faster wear and possible failure. This increased load can also have an adverse effect on fuel consumption. The problem is particularly noticeable in winter, when the heating is less efficient. A similar situation occurs in the summer months, when the air conditioning does not cool enough, although it is technically fine.

Both experts and vehicle manufacturers recommend changing the cabin filter at least once a year or every 15 to 20 thousand kilometers. This interval should be shortened by drivers who often drive in the city, in dusty environments or in areas with a high incidence of pollen. It is ideal to replace the filter at every regular service inspection.
In most modern cars, replacing this part is simple, it only takes a few minutes and many drivers can do it themselves. Some motorists try to save money by cleaning the old filter, but experts do not recommend this, because microorganisms and fine particles cannot be completely removed from it. When buying a new filter, it is worth choosing the version with active carbon. It not only captures dust and pollen, but also absorbs harmful gases or unpleasant odors, which significantly improves the air quality in the cabin.
