Replacement purifier cartridges for the UltraPress™ are designed to last 300 cycles (40 gal. / 150L). Lifespan will decline when purifying water with high levels of silt, sediment or tannins. Cartridge press time increases towards the end of the cartridge lifespan; when press time reaches 25-30 seconds, the cartridge should be replaced. Cartridge continues to protect, even as press time increases.

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.
