4" Custom Size Merv 11 Allergy Pleated - Case of 4

PLEATED MERV 11 (Allergy Capture Capacity) CUSTOM SIZE 4" FILTERS

*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 4 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. WIDTH will always be 3-3/4"

*Select correct square inch area

Example:

H = 16" L = 22"

Square inch area (16 x 22 ) = 352

Select 300-699"

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
