The mask fits well, and wears a total enjoyable. Above all, it also holds - have beards - nice tight. Worn I have been at decluttering an apartment (much dust) and in the purification of a (slight mildew) bath. In both cases, the masks have not disappointed me. The cleaner I could apply everywhere, and after the exposure time I could clean the affected areas sufficiently before I and washing dishes the tiles. From chlorine I got in this time with nothing. However bothers me breathing the unpleasant smell for me, the mask gives off, and I can not quite place properly. After about 30 minutes my glasses begins to fog up easily. This I take then always as an opportunity to take a break and to get some air, why does not disturb me. Here I fiddle then very carefully so that nothing gets inside the mask. Longer than half an hour at a time I do not think it is also already subject to such a mask.
Conclusion: Although overall the benefits outweigh the mask for me, I can give her account of the very unpleasant odor for me only 3 stars. For this reason, I wear them only when it is absolutely necessary, and never more often on a day like three times.
