Minimum Filter Requirements

The Airflow Descriptor is the 2 digits immediately preceding 
the hyphen (-) in the furnace model number. The model 
number is located on the rating plate inside the access panel.

Areas and dimensions shown for cleanable filters are based 
on filters rated at 600 ft (182.9 m) per minute face velocity.

Typical filter sizes are shown; however, any combination of 
filters whose area equals or exceeds the minimum area 
shown is satisfactory.

 

Filter Location

The filter on your furnace will be located in one of several places 
on the unit, depending on which furnace style you own. See the 
sections following to determine where your filter is located.

Filter Location—Upflow Models (Side Return)

If the filter is located in an external filter rack or cabinet on either 
side of the furnace cabinet, it may be easily removed, cleaned or 
changed, and reinserted into its proper location.

Filter Location—Upflow Models (Bottom Return)

If the furnace has a bottom return air, remove the lower front 
panel by lifting up and pulling out. The filter(s) may be removed 
by lifting up and sliding toward the front. Replace in a reverse 
procedure.

Filter Location—Counterflow and Horizontal Models

The filters in counterflow and horizontal furnaces are typically 
placed by the installer into the return plenum of the furnace.
