***It is made of non-woven polypropylene with PTFE,which has been used as filter patches for mushroom growing bags for a long time.***
***0.2 micron filter means it has a filtration rate of 99.98%***
***These filters are one of the best choices for your mushroom cultivation, especially for long term incubation projects. as a nature of the material, those filters can be used within a pressure cooker, steam sterilizer or autoclave. they are reusable and highly durable.***
***The filters are thin, you can very easily adapt them to other sizes and containers.***
When you stick the filter paper to other surface with glue, please make sure apply glue only on the PTFE membrane side, which you feel smoother than the other side.

Not good quality, it was smooth on one side and fuzzy like cotton on the other side. Eventually these will shred unlike he ones that Paul Stamets sells on Fungi Perfect. This is the first of two orders that I had to return in one week Amazon's not a good place to buy synthetic filter discs I have come to find out
