Why do all cars have cabin air filters? Simply to protect the occupants. The air coming into the car from outside contains pollen, dust, soot, smoke, tire and brake wear, ozone, gases, benzene, and sulfur compounds. Depending on the region, there might be more or less of one substance or another. To perform optimally, the cabin air filter must be regularly replaced.
Those without a pollen allergy are fortunate. Those who do have one appreciate a high-performance cabin air filter from MAHLE.
Depending on the condition, spring or fall are the best times to change the cabin air filter. After all, every driver wants their air conditioning to work efficiently in the summer.
However, over time, if the filter becomes clogged, it has a much lower capacity to trap pollutants.
This means for the occupants: a much higher concentration of pollutants similar to those found at the roadside.
And for the heating and cooling system: performance losses up to complete failure.
MAHLE cabin air filters protect against:
Did you know that during a one-hour drive, up to 100,000 liters of air can pass through a car's cabin? For commercial vehicles, it's even up to 540,000 liters. It's a good thing if a high-performance cabin air filter lets only clean air into the passenger compartment. Especially since fine dust particles can be harmful to health because they penetrate deep into the lungs and may cause inflammation or allergies. Cabin air filters keep such harmful substances out of the passenger area. Drivers can breathe easy! Purified air and clear windows contribute to health, concentration, and well-being. Installed before the heating or air conditioning systems, they also protect these components from airborne contaminants.
MAHLE offers pure particle filters (LA) that retain solid substances such as pollen and fine dust. The more powerful three-layer combination filters with an activated carbon layer (LAK) additionally capture odors and gaseous substances like nitrogen oxides, gasoline vapors, and ozone.
The cabin air filter CareMetix® with S5 broadband technology takes it a step further. It provides fivefold protection through its five layers. It filters not only conventional substances from the air but also light and intense odors, mold, bacteria, allergens, and harmful gases such as hydrocarbons, nitrogen oxides (NOx), and sulfur dioxide (SO2) very effectively.
