Meltblown cloth filtering effect detection

1. Filtration efficiency testing, for oily media and salty media, simulation testing is required, and only if they meet the requirements can be considered as passed. There are three levels, level 1, level 2, and level 3.

2. The protection effect is divided into four levels: A, B, C, and D. The level is determined according to the positioning requirements of the product.

The protection effect level is set according to the air quality category in the national air quality standard. The protection effect level is divided into four levels from low to high: D, C, B, and A. The corresponding use environment is as follows: D level adaptation For moderate (PM2.5 concentration ≤150μg/m3) and below, C level is suitable for severe (PM2.5 concentration ≤250μg/m3) and below, B level is suitable for severe pollution (PM2.5 concentration ≤350μg/ m3), Class A is used when the PM2.5 concentration reaches 500μg/m3. Wear a mask reasonably in accordance with the requirements of the standard, which can reduce the inhaled PM2.5 concentration to below 75μg/m3, and make the air quality inhaled reach a level of good or above.
