HEPA high efficiency filtration technology of bus air purifier 2021-05-07

HEPA high efficiency filtration technology is one of the most mainstream purification methods of bus air purifier, and the main purification object is particulate matter in the air. HEPA air filter is widely used in high-end air purifiers in the market. It is an internationally recognized high-efficiency filter material with small pore size, large adsorption capacity and high purification efficiency. HEPA is the abbreviation of high efficiency particle air filters. It is recognized as one of the best high-density filter materials in the world. For 0.3 µ The filtration efficiency of 99.97% can be achieved when the particle dust is more than 5 m. It has a strong purification effect on smoke, suspended particles, bacteria and viruses.

The dust particles in the air move with the air flow in inertial motion, irregular motion or under the action of some field force. When a moving particle collides with an obstacle, the attraction between the particle and the surface of the obstacle makes it stick to the obstacle. HEPA is composed of many disorderly interwoven fibers to form numerous barriers to particles, allowing the wide space between fibers to allow the smooth passage of air.
