Synthetic Filter Discs are used by many mushroom cultivators. From those only using a few jars of spawn to act as spawn masters in commercial production, to those involved in smaller home cultivation. These synthetic filters discs fit precisely on a variety of canning jars that are commonly used by toady’s cultivators. Usage of these discs allows a fresh, constant air exchange but prevents the entrance of unwanted contaminates.

Our synthetic filter discs are able to be used within a pressure cooker, steam sterilizer or autoclave. They are reusable and highly durable.
