I love these masks
I love these masks. They are comfortable. They are reusable. The can produce a good seal which is necessary for the fit test. One can throw them in the dishwasher. They are FDA and NIOSH approved. They have children's sizes. Considering the new Delta Variant for COVID-19, this is the mask one should be wearing. You do have to fool with the straps to get the right strap and the right fit.
