Not too sure on the thickness of these but they seem to work well for now, not sure how long they will hold up after multiple uses.

I really like how adhesive these filter discs are. You can apply them to your air exchange holes on your spawn jars and pressure cook sterilize, and the patch stays firm and will not blow off during the PC like some of the cheaper micron adhesive patches. Thumbs up 👍 , quality product that’s well made and easy to use. Mush Luv 🍄
