<p>The present invention is an improved method of employing a wet/dry vacuum cleaner to collect liquid and wet materials. The method of the present invention employs a liquid impenetrable filter (10), preferably comprising an expanded polytetrafluoroethylene filtration medium and a liquid-tight gasket seal (24). By employing a hydrophobic filter that is liquid impenetrable, the present invention provides wet pick-up without the need to remove the wet/dry vac filter and without the risk of filter degradation. Numerous benefits are provided with the present invention, including better filtration for both wet and dry material collection, effective aerosolized liquid containment, and easy filter cleaning and rejuvenation.</p> |
