Disclosed herein is a method for reducing internal combustion engine contaminate and additive particulate matter from a particulate filter the method including accessing the filter and entraining particulate matter in a fluid stream. Further disclosed herein is an internal combustion engine particulate filter system including a canister, a filter media mounted in said canister and an access opening in said canister. Yet still further disclosed herein is a method for determining condition of a particulate filter in situ including establishing a vacuum value for a clean particulate filter in situ, establishing a vacuum value for a used particulate filter in situ; and comparing the established value for the clean filter versus the used filter.

The invention claimed is: 1. A method for reducing diesel contaminant and additive particulate matter in an internal combustion engine particulate filter comprising: accessing said filter in an installed condition; entraining said contaminant and additive particulate matter in an active, pulsating

The invention claimed is: 1. A method for reducing diesel contaminant and additive particulate matter in an internal combustion engine particulate filter comprising: accessing said filter in an installed condition; entraining said contaminant and additive particulate matter in an active, pulsating positive pressure fluid stream flowing in a direction opposite a fluid flow direction through said filter during normal operation of said filter while in the installed condition; and applying a negative pressure to said filter. 2. A method for reducing diesel contaminant and additive particulate matter in an internal combustion engine particulate filter as claimed in claim 1 wherein said negative pressure is applied to an end of said filter associated with fluid entrance during normal operation of said filter. 3. A method for reducing diesel contaminant and additive particulate matter in an internal combustion engine particulate filter as claimed in claim 1 wherein said stream is a gas. 4. A method for reducing diesel contaminant and additive particulate matter in an internal combustion engine particulate filter as claimed in claim 1 wherein said stream is a liquid. 5. A method for reducing diesel contaminant and additive particulate matter in an internal combustion engine particulate filter as claimed in claim 1 wherein said stream is air. 6. A method for reducing diesel contaminant and additive particulate matter in an internal combustion engine particulate filter as claimed in claim 1 wherein said stream is water.
