Arrived super quick, seems like a good deal
There's not much to say about filters I suppose, except that they look like the real thing! At least I hope they are, since I am trusting them for my health. I got them to go in my masks because I live in CA near all the fires in the Bay Area. They seem to reduce or eliminate the smell of the smoke coming through my mask, so I think they are doing their job. They arrived super fast, and there was even a quality check sheet from the factory inserted into package that listed an expiration date. That was helpful, because I had no idea that filters expire. As others have noted, these are not the kind you want if you are specifically concerned with the spread of Covid. These are for air pollutants such as smoke and smog.
