The pad is made from premium CELdek media, which indicates it uses high-quality corrugated cellulose. This material is known for its excellent water absorption capabilities, making it effective in cooling applications.

The pad dimensions are 41.25 inches in length, 22.25 inches in width, and 8 inches in height, which provides a substantial surface area for air cooling. The thickness of 8 inches contributes to the pad's efficiency and durability, thanks to its multi-layer design which ensures a longer lifespan and better performance.

Installation is straightforward as it fits easily into existing evaporative coolers. Maintenance-wise, the pad is quite durable but will require periodic replacement to maintain optimal performance. It's worth noting that the pad is on the heavier side (10.78 pounds), which might make handling and installation a bit more challenging for some users. This product is well-suited for those seeking a durable, efficient, and environmentally friendly swamp cooler pad for medium to large evaporative coolers.
