Description
Round filter mounts directly to the face without a filter case.
Since air is trapped from the entire part of the filtration, it has low intake resistance, making it very easy to breathe.
It has passed the RL2 and can be used safely even in environments where oil mist exists.
From the Manufacturer
3M Replacement Dust Mask offers a line of products that meet national standards of 2 and 3.
It has a single type that distributes the filter material on the front and a dual type for left and right handling.The dual type has a half-sided and all-round shape for a variety of jobs.

Allows air to enter from all sides for easy breathing.This product does not have a filter case and is a round filter that attaches directly to the surface.Since air is trapped from the entire part of the filtration, it has low intake resistance, making it very easy to breathe.Also, since it has passed national certification, it can be used safely even in environments where oil mist exists. |
BMF filter for high particle captureBMF filters are designed to trap micro dust and retain their shape.Utilizing non-woven technology the fibers are electrostatically charged to the fiber layer filter, which produces a high particle collection efficiency.Its electrical performance will not decrease over time, even in high temperature and humid environments. |
Easy to install with bayonet systemThis is a dual filter media for 3M replacement dust masks.The bayonet method allows for easy installation by combining the filtration material with the uneven face and face and turning 90 degrees in the clockwise direction. |
This product has passed national certification with high particle capture.
Dust masks are divided into two large types, either disposable or replaceable, depending on the shape.Each is also categorized in 3 stages by particle capture efficiency, which is the most efficient one to classify 3 and the lower one is divided into 1.In addition, the particle capture efficiency test is done with sodium chloride (NaCl), a solid particles, or a phthalate dioctyl (DOP), a total of 12 types.Filter material 2071 is a replacement dust mask (R) and measures L using phthalate dioctyl (DOP), which is a liquid particle particles, and is certified by the National Certification that has received a particle collection efficiency of 95.0% or more.In addition, the filtration material 2091 has passed the national certification that has been classification 3 of particle capture efficiency of 99.9% or more, so it is RL3 (*2).
1. The average measurement of the particle collection efficiency of the filter material 2071 is 98.6%.
2. The average measurement of particle collection efficiency of filtration material 2091 is 99.99%.
