The invention is directed to a microbiological interception enhanced filter medium comprising a microporous structure having a mean flow path of less than about 2 microns and made of an array of active particles. At least a portion of the surface of microporous structure has formed thereon a microbiological interception enhancing agent comprising a cationic material in combination with a biologically active metal. A microbiological interception enhanced filter medium of the present invention provides greater than about 4 log viral interception, and greater than about 6 log bacterial interception.

A method of separating gaseous effluent from carbon fibers which allows the effluent to be reused comprising: a) providing a collection chamber containing a gaseous effluent and carbon fibers which have been formed by a continuous gas phase reaction, said collection chamber including top and bottom portions and including exit tubes affixed to the bottom of said chamber; b) removing said carbon fibers from said collection chamber by compressing the carbon fibers from said bottom portion of said chamber into said exit tubes; wherein said compressed carbon fibers form an airtight seal preventing the escape of said gaseous effluent from said chamber and preventing the dilution of said gaseous effluent. 2. The method of claim 1 wherein said compressed carbon fibers are collected from said exit tubes and are formed into bundles. 3. A collection chamber for separating gaseous effluent from carbon fibers which allows the effluent to be reused comprising: a top portion and a bottom portion, said top portion including an opening for receiving vapor grown carbon fibers and gaseous effluent from one or more reactors connected to said chamber; said bottom portion including a chamber for collecting fibers dropping from said top portion; exit tubes affixed to said bottom portion for receiving carbon fibers; and a piston affixed to said bottom portion for compressing carbon fibers from said bottom portion into said exit tubes; wherein said compressed carbon fibers form an airtight seal which prevents the escape of said gaseous effluent from said chamber and prevents the dilution of said gaseous effluent. 4. The collection chamber of claim 3 including an exhaust for removal of said gaseous effluent from said chamber. 5. A method of separating gaseous effluent from carbon fibers comprising: a) providing a collection chamber containing a gaseous effluent and carbon fibers which have been formed by a continuous gas phase reaction, said collection chamber including top and bottom portions and including exit tubes affixed to the bottom of said chamber; b) removing said carbon fibers from said collection chamber by compressing the carbon fibers from said bottom portion of said chamber into said exit tubes; wherein said compressed carbon fibers form an airtight seal preventing the escape of said gaseous effluent from said chamber, wherein said gaseous effluent is recycled.
