The UltraPress and Ultralight replacement purifier cartridges are forward/backward compatible with each other and do utilize the same purification technology. The outer shell and the flow channels do differ (horizontal vs vertical flow channels). The UltraPress cartridge's flow channels are stronger and more durable in comparison.
