finally started my egullet account to reply to this topic these will work fine. I work in the water treatment field (among other things) and these are commonly used for water treatment, filtration, etc. The polypropylene bags seen here would work great: http://www.mcmaster.com/#standard-filter-bags (click Mesh filter bags) to see a good selection these are also FDA compliant. I don't see the need to pay an extremely marked up cost for the same product - clever marketing by the superbag people!
