This is my third order and very happy with consistency and performance

Using these for air filtration on grain jars for medicinal mushroom mycology. They are large enough to use just one, and still provide a good amount of air exchange. Under a microscope the fiber looks consistent, without any obvious gaps or holes. The case these come in is also great, it is rigid enough to provide protection for the rather thin sheets - keeping them flat, clean and dry.

These filters work great for mycology grow bags. They're the perfect size, they stay put well, and most importantly, they filter the air keeping your grow bag sanitary and safe from contamination.
