Modern evaporative cooler pads are made from corrugated cellulose sheets treated with anti-rot agents. These pads provide superior cooling power due to their unique design. Rigid Media swamp cooler pads are easy to clean and will last for many years with proper yearly maintenence. These pads are used in several newer style cooler brands such as Mastercool, Aerocool, and Ultracool. They are also used in agricultural buildings like green houses and animal enclosures.
