Ultralight Purifier Cartridge

This cartridge is specifically designed to fit the Grayl Ultralight, Quest, and Legend water purification systems.

You should replace the cartridge when the press time begins to exceed 25 seconds or when you have reached the 40-gallon (150-liter) limit. As the filter media becomes saturated with trapped contaminants, the flow rate will naturally slow down.
