What the AI looks for in Evaporative Cooler Pads

Media type
Aspen (excelsior) pads are cheap and are replaced each season; rigid cellulose media costs more but lasts several seasons This choice sets cooling efficiency, maintenance and whether you need a frame conversion.
Rigid media thickness
Rigid media is commonly 8 in or 12 in thick and must match the cooler's design The cabinet and the water distributor are built for a specific depth.
Pad size
Measure the pad frame's height and width, and buy to that size or cut oversize aspen to fit Gaps let air bypass the wet media.
Portable cooler pads
Buy pads specified for the exact portable model Portable units use proprietary pad shapes.
