Knowing when to replace your cartridge

Press time gradually increases as the cartridge approaches end of life. When press time hits 25–30 seconds, it's time for a replacement. Rest easy: even as press time increases, your cartridge continues to protect you from contaminants — performance stays strong right up to the end.
