Device for collecting particulate matter

An improved device for collecting particulate matter suspended in the ambient air through the use of a low pressure air source, comprising:

• a container extending between an open first end and a closed second end defining a container interior;
• a container output communicating with said container interior located proximate said closed second end of said container;
• a filter cassette comprising a collection filter permanently fused to a filter holder, wherein a top surface of the collection filter is permanently fused to a bottom surface of a flange of the filter holder;
• a filter support positioned under said collection filter, wherein the filter support prevents distortion of the collection filter during an operation for the collecting particulate matter;
• a foam filter located in said filter cassette located upstream from said collection filter;
• a retainer having a retainer input removably secured to said open first end of said container for retaining said filter cassette between said retainer input and said container output;
• and
• an output connector for connecting said container output to the low pressure source for drawing ambient air into said retainer input for enabling said collection filter to collect particulate matter suspended in the ambient air entering said retainer input.
