I recently bought some KN95 made by Powecom, also on the FDA EUA list, on sale for $20 for 10 masks on the Office Depot website (including delivery!). They seem to be decent quality although there's still some leakage around the nose, but that seems to be a common problem with this type of mask from what I can google. I tried sticking a little padding underneath around the nose and that seems to help a little.

Thanks.  As you said, these are on the EUA list. And, moreover, each bag of 10 has a unique anti-counterfeiting code that can be checked.
The reviews at Office Depot indicate it is maybe too small for a bigger face.  (But, for children this might be a good thing.  I do NOT know if it is an appropriate size for children as it is described as an adult mask.)

I believe someone here suggested using dancer's tape to get a better seal. (A quick Google indicated double sided sticky strips were about 20 cents each.)
