Remember that the use of single use masks must always comply with the rules of the Danish Working Environment Authority regarding limit values, among other rules - and for a shorter duration: no more than three hours per day or until you notice increased breathing resistance.
If the single use mask incorporates an "exhalation valve", this helps to reduce heat accumulation inside the mask.
General description of level of protection:
| FFP1: | Non-toxic solid and liquid aerosols. |
| FFP2: |
Solid particles and liquid aerosols with low to medium toxicity. |
| FFP3: |
Solid particles and liquid aerosols with medium to high toxicity. |
| R: |
Reusable - for multi-use masks. |
| NR: |
Non-Reusable - for single use masks. |
| D: |
D-labeling indicates that the mask has been tested for its protection against Dolomite dust clogging - (Dolomite tested). This means that the resistance to breathing only increases slowly as the dust is absorbed. |
