Bests & Worsts Reviews from Amazon

In March I started wearing a 3MN95 mask I had on hand until the rubber band broke. With the unavailability of N95 masks I then went to KN95 masks. Of the three KN95 mask suppliers I've used, this mask appear to be best because while the elastic ear loops are tight they assure that the mask seals well which is the objective here, after all. The tight seal is made more bearable by virtue of the soft material used at the edges. When testing the edge leakiness by breathing hard in and out I didn't notice any leakage. As for the filter efficiency I'll have to depend on the FDA testing for that. Overall, the best of the masks I've used, including the 3MN95 which is too restrictive for long, active use.
