[MacWillow]

The main functions of a car air conditioning filter are: 1. Provide fresh air. It prevents the car windows from fogging up, ensuring clear visibility for the driver and safe driving; it supplies fresh air to the passenger compartment, preventing occupants from inhaling harmful gases and ensuring driving safety; it effectively sterilizes and deodorizes. 2. Ensure safety and hygiene. It keeps the air in the passenger compartment clean and free from bacterial growth, creating a healthy environment; it effectively separates solid impurities such as dust, core powder, and grinding particles from the air; it efficiently intercepts pollen, ensuring that passengers do not suffer allergic reactions that could affect driving safety. 3. Adsorb harmful substances. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air; it has strong and durable moisture adsorption capabilities. 4. Filter solid impurities. The car air conditioning filter fits tightly into the housing, ensuring that unfiltered air does not enter the cabin. It separates solid impurities such as dust, pollen, and grinding particles from the air.
