3M mask p95 series masks 8576 and 8577 difference is what

1) The only functional difference between 3MTM8576 and 8577 is the applicability to different categories of odorous gaseous substances. 8577 is only applicable to odors generated by certain organic substances and 8576 is only applicable to odors generated by certain inorganic acidic gases.

(2) P95 has 95% filtration efficiency for non-oily particulate matter.

3)Organic and inorganic substances are different substances, so the activated carbon used for adsorption and filtration is different.

4)Increasing the filtration efficiency does not guarantee a higher protection effect, because, after putting on the mask, there will still be pollutants inside the mask, whose main source is not from the filter media penetrating in, that is, whether it is P95 (95%) or FFP3 (99%) filtration efficiency, the actual efficiency of the mask filtering airborne particles is already high and not much different from each other, but from between the mask and the face The amount of air particles leaking into the mask from the seal between the mask and the face will be much higher than the penetration of the filter media, that is to say, the protection effect of a mask with 90% filtration efficiency, which is very suitable for your face shape, may be greater than that of a mask with 99% efficiency, but not suitable for your face shape, so it is important to choose a mask that is more suitable for your face shape, and choosing a mask with good comfort will facilitate longer wearing time and further reduce the The amount of pollutants entering your body.
