In terms of equipment, MF methods call for appropriate filtration apparatus containing a base sustaining a porous disc, on which the filter is put, and a sterilized filter channel, which can be secured to the base, securing the filter in position. A variety of filtration systems are readily offered, consisting of several devices in the type of manifolds, to ensure that greater than one sample can be filtered at when.

The filter system is attached to a suitable vacuum source to attract the samples through the filter. An example is the Millipore EZ-Stream system, which can run the filtered sample straight to drain pipes, thus conserving time spent emptying and cleaning up the waste sample containers used with traditional laboratory vacuum cleaner pumps.
