Adhesive Filters 18mm

The filters can be applied to jar lids or other mycelium culture containers to allow your culture to breathe while protecting it from contamination present in the ambient air.

• Filtration efficiency of 0.3 microns
• Made with strong 3M adhesive
• Hydrophobic & Oleophobic
• Made from 100% recycled materials
• Fully autoclavable, high temperature resistance

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 in front of laminar flow.
