How do you guys sterilize the filters? the ones on amazon are cheap but non sterile, the sterile ones are kinda expensive.
Buying sterile filters is the easy button here. Depending on your setup, if you use the filter paper discs, you can find ones that are autoclaveable (Tisch Scientific), but if you’re concerned about sterile filter prices, I’m going to assume you don’t have an autoclave.You buy the sterile filters.
