1. A portable filtration unit comprising:
- a. a prefilter modular housing defining a fluid inlet and a fluid outlet;
b. a prefilter removably attached within the prefilter modular housing intermediate the fluid inlet and fluid outlet, for filtering selected particulate matter from fluid entering the prefilter modular housing;
c. a modular casing detachably connected to the prefilter modular housing and defining an inlet in fluid communication with the fluid outlet of the prefilter modular housing when the modular casing and prefilter modular housing are connected and defining an outlet;
d. means for rigidly connecting the prefilter modular housing on top of the modular casing;
e. a filter attached within the modular casing for filtering selected particulate matter from fluid entering the modular casing;
f. means, attached within the modular casing, for drawing a substantial volume of fluid through the prefilter modular housing inlet, prefilter, modular casing inlet, and filter; and
g. means for facilitating transport of the modular casing, comprising;
i. a handle connected to the modular casing at a first location; and
ii. a support means connected to the modular casing at a second location remote from the first location.
