Testing and Evaluation

How it works

Each filter, component, or part cleaned by Carolina Filters must pass a final test, or series of tests, for cleanliness and integrity evaluation. For filters, test procedures follow standards that are provided by the end user and the filter manufacturer. For integrity evaluations, filters are tested to standards, such as the ARP901 Bubble Point Test Standard. Additional tests include, but are not limited to, wetted air flow testing and dry air permeability. 


What we do

Prior to certifying a filter for reuse, Carolina Filters performs visual inspections, wetted testing under isopropyl alcohol or water, and at times, dry air permeability testing. Customized testing reports collate data in a user-friendly manner to allow the end user to document and quantify the level of cleanliness and integrity of their component. 

Carolina Filters maintains a detailed database that records and stores all final test data for each component tested. Filters and associated parts are serialized in-house, and each filter will carry its serial number throughout the life cycle of that part. 

Each test report is customized to the need of the end user. Most reports contain some or all of the following information:

  • Filter Set Identification
  • Individual Test Values by Serial Number
  • Testing Criteria
  • Micron Rating and Filter Manufacturer
  • Number of Cleaning Cycles
  • Filter Set Statistics

"Throughout my career at Carolina Filters, our unwavering commitment to new and cutting edge technology has established us as the world's leader in metallic filter cleaning and testing."
