Inquiry (采购产品): looking for vent material Dear National Filter Media Corp. I am looking for a nonwoven filter material that is able to contain particles down to 0.5 micron (~ 0.00002"). I would like to know if you have such material(s). If yes, then I would like to know the cost for a few square feet at this point to prove out the concept. Thanks in advance.
