The practical role of air filters in our lives

In the current environment, air problems always plague us. At this time, air filters play a significant role in daily life. Air filters help to improve our air quality and prevent harmful substances from harming the body. Let's look at the air filter's role in detail.

An air filter is a device that captures dust from a gas-solid two-phase flow through the action of porous filter material and purifies the gas. It purifies the air with low dust content and sends it into the room to ensure the process requirements of the clean room and the air cleanliness in the general air-conditioned room.

Air filters effectively intercept dust particles without creating excessive resistance to airflow. The tangled fibers form numerous barriers to particles, and the wide spaces between the fibers allow airflow to pass smoothly. Particles smaller than 0.1µm (microns) do diffusion motion, and the smaller the particles, the higher the efficiency; the particles larger than 0.5µm are mainly used for inertial motion, and the larger the particles, the higher the efficiency.

In order to make the airflow around, a small resistance is created. The sum of the resistance of countless fibers is the resistance of the filter. The resistance of the filter increases with the increase of the airflow. By increasing the area of the filter material, the relative wind speed passing through the filter material can be reduced and the resistance of the filter can be reduced. The trapped dust creates additional resistance to the airflow, so the resistance of the filter in use increases gradually. The trapped dust forms new obstacles and, as a result, the filtration efficiency is slightly improved.

Most of the captured dust accumulates on the windward side of the filter material. The larger the filter area, the more dust it can hold, and the longer the filter life. The more dust accumulates on the filter material, the greater the resistance. When the resistance is too great to be allowed by the design, the life of the filter is over. Sometimes, the excessive resistance will cause the dust captured on the filter to fly away, and the filter should be scrapped when such secondary pollution occurs. If the filter material is electrostatically charged or the dust is electrostatically charged, the filtering effect can be significantly improved. Due to static electricity, the dust changes its trajectory and hits the obstacle, and the electrostatic force participates in the sticking work. Will turn to domestic enterprises, imported bearings will decline.

The air filter is to obtain clean air that can meet the standard. Generally, the filter for ventilation is to capture and adsorb dust particles of different particle sizes in the air to improve air quality. In addition to absorbing dust, chemical filters can also be used. Absorb odors, are usually used in biopharmaceuticals, hospitals, airport terminals, human settlements, and other places. Generally, filters for ventilation are widely used and are needed in the microelectronics industry, coating industry, food, and beverage industry, etc. So the role of air filters in our lives is very important.
