Which side of this pre-filter faces outward?
When I received my latest Hepa filter kit, the prefilter was placed on the filter with the metal corrugation facing outwards. This is opposite from how it's been installed in our system. I'd like to verify correct installation of the prefilter.
Thank you for your question on the model ACCGSFHP10 Hepa filtration filters. The pre-filter should be installed with the metal corrugation on the inside (not visible).
