This can be used repeatedly, unlike disposable masks for covid. I am happy with it principally because it lets you breathe freely. The filters even have a pleasant aroma, not over powering. The mask is not designed for covid and it is a barrier protecting others from me, not the other way round.My small grip is that after a few uses, the elastic bands are fiddly to put on/off and tend to slip on my hair once worn. As it makes me look like an alien, the replusive effect on my fellow mankind, is quite agreeable.
