System and methods for evaluating an air purification system

A method for evaluating an air purification system, the method comprising:

• generating, with a filter test station, breakthrough curve lookup tables for predetermined air flow rates and corresponding to test filters having predetermined filter volumes and predetermined filtration media, where breakthrough curves of the breakthrough curve lookup tables are generated by
• injecting, with the filter test station, a multiple contaminant mixture into an upstream air flow on an upstream side of a test filter of the test filters, and
• measuring downstream concentrations of contaminants in the multiple contaminant mixture in a downstream air flow on a downstream side of the test filter;
• measuring, with the filter test station, in-service filter downstream concentrations for contaminants of the multiple contaminant mixture in the downstream air flow on a downstream side of an in-service filter, the in-service filter being taken from a first passenger vehicle at a predetermined service life time;
• and
• sizing air filtration for a second passenger vehicle based on a correlation between the predetermined service life time and a performance of the in-service filter, where the correlation is determined based on the in-service filter downstream concentrations and the breakthrough curve lookup tables.
