The PURE air conditioning filter element adopts dual purification technology of physical interception and chemical decomposition. When the air outside the car enters, the dense filter first captures PM2.5, pollen and other particulate matter, and then absorbs harmful substances such as formaldehyde and exhaust gas through the activated carbon layer. Some models are also equipped with an antibacterial layer that can inactivate 99% of common bacteria. Strictly matches the original factory specifications to ensure that the air intake volume is 20% higher than that of ordinary filter elements, while achieving a 0.3μm particle filtration efficiency of over 95%. The three-in-one protection system makes the air in the car as fresh as a forest, and the 3-minute quick disassembly and assembly design makes family cars more worry-free.
