For years, I am looking for a mask that I can wear during exercise. Whether against smog or pollen in the air, with most masks earlier times this was very difficult, because the breathing resistance were too high. With effort, the air is scarce and they are liberated from - with corresponding consequences. The current generation of FFP1 + 2 3M (Aura) (also Moldex and Dräger have followed suit) you can feel by inhalation barely. Thanks to the valve downward exhalation is as usual and can easily Glasses rarely shod. Only the bands are as already discussed here not very stable. At weaning, about to have a drink, it can ever happen to a tearing - With the knowledge and necessary care but this rarely happens - this is at Dräger and especially Moldex solved much better, but associated with higher costs and larger pack size ,
Allergenic pollens are usually 17-50 microns in size, and can usually be already with the FFP1 even filter out very well on very bad days - years were in pharmacies so FFP1 masks. Recently, however, these usually on only FFP2 masks. Everyone needs to decide selsbt.
Conclusion: A super mask at a fair price. Can adapt well to different head shapes and take with you anywhere thanks to a tiny pack size.
