Cabin air filter, commonly known as pollen filter, the function of automobile air-conditioning filter is to filter the air that enters the cabin from the outside to improve the cleanliness of the air. The general filter material refers to the impurities contained in the air, small particles , Pollen, bacteria, industrial waste gas and dust.
The effect of the air-conditioning filter is to prevent such substances from entering the air-conditioning system and destroying the air-conditioning system, providing a good air environment for the passengers in the car, protecting the health of the people in the car, and preventing glass from fogging.
Compose of cabin air filter
The filter is a small pleated unit, usually made of engineering materials or paper-based multi-fiber cotton. Before the air enters the interior of the car, the air passes through this filter, trapping any pollutants in the air to prevent them from penetrating into the air you breathe.
The cabin filter is a type of air filter that may be similar to an engine air filter in some aspects (for example, pleated to provide a lot of surface area in a small package). However, it is usually made of different materials, the main material being the charcoal layer among many elements. Like some engine air filters, dust and pollen filter elements are also electrostatically charged, which means that they are made of fibrous particles with positive or negative electrostatic charges. Airborne particles are negatively or positively charged, so they are attracted to oppositely charged fibers.
History of cabin air filter
In the late 1980s and early 1990s, only some European luxury cars had them. It is more common in new cars. In many high-end cars, there may be two filters, or even three. Sometimes they are parallel (side by side), sometimes they are connected in series (one after the other with a certain interval between them). Sometimes they are far apart from each other.
Cabin Air Filter Types
Regular Cabin Air Filters are generally made of a specific environmentally friendly filter material after processing and folding, mostly white single-layer. Regular cabin air filter only captures particles. It doesn’t remove orders or harmful gases.
Activated Carbon Cabin Air Filter is an activated carbon filter cloth made of non-manufactured cloth (non-woven fabric) on both sides with tiny granular activated carbon in the middle, and then deep-processed into an air-conditioning filter.
