*Due to increasing shipping charges we will no longer make filters any longer than 25 inches if you require a longer length please consider halving your length and combining two filters
- STEP 1 - Enter exact size (height and length) in inches
- STEP 2 - Select correct square inch area*
Pricing is by the case of 12 individual filters.
Multiply your height and length measurements to obtain correct square area
Measurements must be in INCHES and EXACT
Note: Some filters are marked in nominal sizes and will measure smaller. ALWAYS double check measurements.
*Select correct square inch area
H = 16" L = 22"
Square inch area (16 x 22 ) = 352
Note: We occasionally combine filter frames to achieve long lengths. This is industry standard and all glues we use are specially classified to be used in these applications
