Airocide APS-200 PM2.5 Reaction Chamber Replacement Kit

Air purifying cartridges (2) for newer model air purifier. My APS-200 is over 13 years old and requires original kit. Light flashes every 12 months as a reminder. Unable to return due box seal tape cut. Both cartridges fit my air purifier but newer electronic components will not activate the kit. Other than initial snap-into-place loading of cartridges, components taken out of box once but never activated. System rejection lights (3) indicate never activated and, therefore, never used. Never shop the internet late at night AND read the fine print! Original retail $269. My loss, your gain. Free pick-up at my location if not too far to drive, of course.
