Working with mold and fungus
"We are faced with a major mold cleaning of objects. We have tube protectors that are used for larger and more long-lasting tasks, as well as filtering dust masks (P3 models) for smaller tasks. Is it enough? and what is recommended?"
When working with mold, fresh air is always the best choice, otherwise it is recommended to use a Turbo system. However, there must be P3 filter, because the degree of separation is a factor of 50 higher than for P2.
The difference is significant between one P2 and P3. P2 is suitable for dusty areas where the dust itself is only dangerous due to the size of the particle, but not property. Whereas for mold, a P3 must be used.
We recommend that you always use fresh air or turbo protection.
