Fix the handheld particulate matter tester on the desktop, place the hair dryer air outlet facing the sampling port of the particulate matter tester at a distance of about 20cm, turn on the cool air of the hair dryer and set it to a low wind; turn on the particulate matter tester, and measure the environment (in a closed room) ), that is, the concentration of particulate matter at the sampling port of the particulate matter tester. The test time is 20 seconds. After the measurement is completed, the number of 0.3 micron and 2.5 micron particulate matter are recorded respectively; the N95 mask or other masks completely cover the sampling port of the particulate matter tester, and the measurement result is The concentration of the particulate matter after the mask filter material is filtered, the test time is 20 seconds, after the measurement, the number of 0.3 micron and 2.5 micron particulates are recorded respectively; for the remaining 4 types of masks, repeat the procedures 2 and 3. The following pictures show the removal rate of each mask and the corresponding 0.3 micron and 2.5 micron particles. It can be seen that the N95 copper mask
(the first one on the top) has the highest removal rate for 0.3 micron and 2.5 micron particles, both exceeding 90%; two A three-layer medical mask (the second and third) has a removal rate of 90% and 51% for 0.3-micron particles, and a removal rate of 100% and 75% for 2.5-micron particles, respectively; the performance of the two ordinary dust masks is inferior Good, the three-layer black copper mask has a removal rate of only 20% for 0.3 micron particles and only 60% for 2.5 micron particles; the two-layer blue copper mask has a removal rate of 0 (invalid) for 0.3 micron particles, which is even 0 (invalid) for 2.5 microns. The particle removal rate is only 42%. classification: N series: N stands for Not resistant to oil, which can be used to protect non-oily suspended particles with no time limit. R series: R stands for Resistant to oil, which can be used to protect non-oily suspended particles and sweat oily suspended particles. The time limit is eight hours. P series: P stands for oil Proof, which can be used to protect non-oily suspended particles and sweat oily suspended particles without time limit. When the carrier of some particulate matter is oily, and these substances attached to the electrostatic non-woven fabric will reduce the electrical properties and allow the fine dust to penetrate. Therefore, the anti-aerosol-containing filter material must undergo special electrostatic treatment to prevent fineness. The purpose of dust. Summary: Whether it is N95 masks, R95, P95, N99, R99, P99, and even N100, R100, and P100 masks with higher filtering functions, they can effectively filter suspended particulates or germs. In addition, FFP1, FFP2 and FFP3 industrial masks that pass EU standards can also effectively filter out particles or germs.
