Evaporative-cooler media must match the cooler’s pad frame, air direction and water-distribution system. Aspen fiber pads are thin, cut-to-fit and inexpensive; rigid corrugated cellulose media is thicker, model-specific and must be installed with the marked top and airflow orientation. Match the part number or measure every dimension before ordering—there is no universal pad.

Buying tips
- Read the cooler’s model plate and pad chart before choosing media; width, height and depth all matter.
- Install rigid cellulose pads with the marked top and airflow direction, and do not force a loose pad to fit.
- Flush mineral buildup from the water system and inspect distribution pads and pump flow; new media cannot correct poor wetting.
