    Hi-Eff Air Cleaners for downflow furnaces

    Usually whe installing a downflow furnace it is in a tight closet with not that much room. When we put in variable speed furnaces we like to put in a hi-Eff media filter maybe Aprilaire 2210. Lots of times they just won't fit or is too much work to rearrange humidifier or vent pipes. Anybody have any ideas for a good airfilter that would work on downflows.

    On downflow, usually the 16x20 or 20x20 fit better than the 25".

    Yep, find the return air and install filter ..

    Aprilaire makes a model that works with upflow/downflow. It's pricey.
