Very good product, by the looks of it, it is original. It came in a resealable 3M bag. Fita perfectly, and feels very comfortable to wear and breath. The package initially went to the wrong location but I was able to contact the post office and get it redirected to my address. I checked the address on the label, it was proper, I think the post office made a mistake with the routing. But I have the product job, and satisfied with it.
Received quickly and in perfect condition. Packed in a cardboard box, and 3M plastic reseleable bags. Looks like an original product. It fits original filters purchased somewhere else. I recommend this product and seller
