I have no idea. The door to the filter is closed tight. I cannot open the filer door. Need to wait for HVAC tech to come over this November. I noticed the package has 6 filters. This should last me 6 years after this November.

Perfect fit. Easy to install. Four pack lasts a year and saves money vs buying similar filters retail. Going to reorder another four pack today.
