I’ve purchased a few ST-AG masks which use this ST-AGX.1 filter. The item I received is labeled ST-AGX.1 and it has all the marking from the manufacturer JZ Strong, but the filters are slimmer than my purchases from other sellers, the difference is very noticeable.I like the masks made by JZ Strong, the ST-AG masks and ST-AGX.1 filters have worked well, my complaint is about the specific filters I received from this specific seller. I purchased more from another source and received what I expected. May be it was a bad batch, reach your own conclusions.

Not bad for light work but anything that causes you to break a sweat will likely soak the filter and makes it harder to breathe and makes you sick in sweat/snot, it’s pretty gross. Flawed design
