Use

Drill a cover with a +-5mm drill bit. Place an adhesive filter, pressing firmly on the edges to make it adhere.

Tip for sterilizing in pressure cookers:

Do not close the lids completely. Leave a small gap which will allow the steam to escape, otherwise the filters risk coming loose under the internal pressure. This also helps prevent the formation of a “vacuum” during cooling, which can damage the filters. Cooling must be done in the cleanest environment possible to avoid contamination. Only open the pressure cooker when the temperature has cooled to room temperature, and close the lids securely at that time. If possible work with it in front of a laminar flow.
