Advantage Filter unit replacement filters

How do I know which filter needs replacing when I get the 75% used light illuminated ?
Remove either of the filters from the Advantage Unit and switch it back on again. If the 75% filter warning light goes out then the filter that was removed needs replacing, if it does not go out then it is the filter in the Advantage unit that needs replacing.
Replacement 2 stage Pre-Filter Pt No BI01830B
Replacement Combined HEPA and Gas Chemical Filter Pt No BI01830A
