If you do remove the lag screws and rock it over ... make sure the gasket between the supply air and return air ducts is in place when you reattach it, or your A/C will not perform well. Ditch the screw on metal return grills and get the newer style from the factory or go something like this route. Either way, the lid on the grill swings down and you simply remove the filter media ... no unscrewing. You can just buy filter media and cut to fit.

Couldn't find this return air grill in the US - Canada Home Depot has them.
