It works but need to improve on packing
It is good and works. Since it is the only kind I have used I can't compare with others. I used it on three brands of disposable 3-layer face masks. It works well on two of them. I will have two other brands to try and will keep you updated.<br />I read the reviews before my purchase and many people complained about the packing. I do too. Total three sheets of it. The back to back is good but two sheets that face to face packed are stick to each other. I peeled them off very carefully. I think the supplier should change a little bit on the way of packing.
