    Which way does the air flow (see pictures)

    I'm replacing the filters in our furnaces but confusion has all of a sudden set in. Someone please let me know which way the air flows on the following furnaces. I stuck a toilet paper to check & both blows left to right so I'm assuming that's the correct way to put in the filters. Thanks!

    Furnace A


    Furnace B

    it flows in throught the filter and up throught the furnace, the top where the pvc vents are would be the exit, the flor being the entrance.
