I thought CFCs were already regulated and the hole in the ozone layer was already patched up years ago. Of course I may be mistaken. In any case, maybe it's better to think about where this filter is intended to be used. Who are the target users? It seems to me that it makes more sense to solicit support from the source of the pollution (manufacturers) rather than the general public. Refrigeration and air conditioning companies, for example, might be more than willing to support your project in the thousands of $$$. Just a thought. :-)
