3M SDust filter [P3]
This product is a 3M dust filter for use with the 6000 series and 7000 series half and full face masks.
Dust filter: Just like a dust mask, a dust filter protects against small dust or liquid particles. This works just like a sieve; the finer the holes, the more dust is retained. These filters are available in three classes, namely P1, P3 and P3.
- P1: protects against annoying, non-harmful dust.
- P2: protects against harmful fine dust.
- P3: protects against toxic fine dust. Use a P3 filter preferably always in combination with a full face mask.
A very fine filter offers better protection, but makes it more difficult to breathe. In other words: a fine filter has a greater breathing resistance. Dust filters with an exhalation valve remedy this.
There are four types of dust filters: for single use and limited use (dust caps), for connection to masks and for connection to motor-driven devices.
