These filters fit neatly within the rim of spawn jars underneath the lid, allowing air exchange but preventing the passage of contaminants. Sterilizable and reusable for life (not for food canning) 99.97% efficient filtration down to .3 microns.
Works well
Nice filters, fit my jars perfectly. Lots of gas exchange. I'm happy!
