I was just rereading the Sprirulina growing article in the July issue of Make, and noticed they recommended screen printing fabric as a filter for gallons of spirulina culture. 40 micron openings would correspond to 325-400 mesh fabric. 100 micron pores would be 140 mesh. Here's a lookup table:

I need many micron filters for straining large quantity of liquid (liter volumes of water-oil emulsion). These filters are expensive from biotech suppliers and only last for some time until they clog. 100 um and 40 um. Is there any way to DIY these? Spinning is not really a solution and applying pressure is also not a good idea. How are these filters made? Does substituting a much cheaper alternative (i.e. drinking water filter or aquarium filter) yield the same accuracy?--
