Abstract
An assembly line for manufacturing filter canisters is disclosed. The method for assembling filter canisters provides a unique serial number for each canister and a database that associates the component lot numbers, activated charcoal weight, and quality assurance test results with the serial number for the filter canister. The manufacturing method can be adapted for assembly of canisters with activated charcoal and an aerosol HEPA filter, canisters with activated charcoal only, and canisters with an aerosol HEPA filter only. Some embodiments can also enable different testing conditions and specifications, activated charcoal loading requirements, labeling specifications, and packaging requirements.
