A range of filtering systems are commercially available, consisting of numerous units in the kind of manifolds, to make sure that greater than one sample can be filteringed system simultaneously.

Providers include Millipore, Sartorius and Membrane Solutions. The filter system is connected to a suitable vacuum cleaner source to draw the samples with the filter. This may be a vacuum line or a stand-alone pump device. Portable pump systems particularly made for usage with MF methods are now readily available. An instance is the Millipore EZ-Stream device, which can run the filtered sample straight to drain pipes, hence conserving time spent emptying and cleaning the waste sample containers made use of with traditional laboratory vacuum pumps.
