The working principle of air filter

There are two main working principles of air filters, one is a physical filter, and the other is an electrostatic filter. Although there are many important differences among them, the filter materials are all fiber media, which are widely used in ventilation and air conditioning systems to collect dust particles. The filter medium of the air filter is a collection of fibers laid in disorder. The size of the fiber allows a diameter in the range from less than 1 micrometer to more than 50 micrometers. The fiber medium can be GlassFiber, polyester, polypropylene or many other materials.
