Activated CarbonToyota Air Conditioning Filter

Diverse materials
1.Activated carbon filter element: Usually, an activated carbon layer is added to the basis of filter paper or non-woven fabric. By taking advantage of the rich pore structure of activated carbon, it has a strong ability to adsorb gases, effectively adsorbing odors, harmful gases such as formaldehyde and benzene, and can also adsorb a certain amount of moisture. However, its ventilation volume is relatively small and the price is also relatively high.

2.HEPA filter element: Also known as the high-efficiency particle air filter element, it can achieve a filtration efficiency of approximately 99.97% for particles with a diameter of 0.3 microns (PM0.3). It can efficiently filter PM2.5, smog, and various tiny particles, with excellent filtration performance. However, it has relatively high air resistance, small air volume, and high cost and price.
