    Missing furnace filter

    I have a Carrier 58HDV furnace but for some reasons, there is no filter along with it although the owner menu say it should. I opened the blower compartment and cannot find it.

    I also confirmed with the previous owner. He said instead, I have to replace the filters installed at the return vents.

    Is there any issue if there is no filter inside the furnace at all? Is it a misconfiguration?

    Thanks,
    Ives

    A long as the filters are present in all of the reurn grilles and they are the "filter grille" type that is good enough

    I see. Thanks for the quick reply. To certain extent, I think this is good because that means I don't need to open up my furnace at all.

    I have no idea what "filter grille" is but I guess I can google it.
