The difference between glass fiber and plastic fiber screen
Glass filter and PP filter (or other chemical compound) in glass filter just rely on the barrier (collision interception and sieve effect) is the chemical fiber, electrostatic adsorption (and not completely reliable test of electrostatic adsorption accounted for a large).
You say that the chemical fiber adsorption should refer to electrostatic adsorption, rather than activated carbon adsorption! The chemical fiber filter screen has no adsorption to the odor! The fiber diameter and pore size of the glass fiber filter screen are much smaller than that of the chemical fiber! The two can produce bacteria, but the bacteria in the fiberglass can not pass through the screen (the bacteria on the wind side can fly out, but they will also be blocked on the screen later).
Bacteria are generally not electrostatic adsorption, so the chemical fiber screen is difficult to obstruct bacteria!!! In addition, according to the test, the dust holding capacity of the glass fiber filter is much larger than that of the chemical fiber! And efficiency will not go down! As for the cost... Now it's about the same! As for the wind resistance, fiberglass is several times the chemical fiber
