Prior to receiving these, I had tried other filters. This is the second time I have ordered these . Well packaged, uniform and easy to put in the pockets on cloth masks. They fit really well and have a nice stiff composition to them. I have used them and washed them after one use when I wash my mask and that has work really well for me though I'm not sure if you're supposed to do that. Very pleased and I have recommended the specific ones to other people
These face cover filters are great! They come in attractive resale packs of three incase you want to add to your Covid safe inventory too.
I would recommend them.
These filters were perfect! received in a timely fashion and fit our masks perfectly. Now we can be safe in a more environmentally responsible manner. Thanks, SewCalMasks!!!
