This unit was installed in 2012, and the filter looked like it had never been changed because of the poor installation. https://www.youtube.com/watch?v=pWLjoGHU63Y)

And I’ve seen dirtier filters in less than 1 year, but I get the point.
I recommended that an HVAC contractor configure the filter so that it’s accessible.
