UltraPress Purifier Cartridge Color:Black and multiple phones or casesReplacement 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.
