How To Calculate The Square Footage Of A Filter Cartridge

1. Count the number of pleats and measure the pleat depth in inches.
2. Measure the length of the cartridge in inches excluding the end caps.
3. Multiply the number of pleats by 2 and multiply that number by the pleat depth. Multiply the total by the length of the cartridge (excluding the end caps) and divide that number by 144.

# of Pleats X 2 X Pleat Depth X Pleat Length ÷ 144 = cartridge square footage


Example:

Number of Pleats (100) x 2
Divided By Pleat Depth .75
Times Length 12.25
Divided by 144
Equals 12.76
