Here's what other sites are saying:

For use with a Grayl filtration cup, the Travel purifier is designed to protect against waterborne viruses, bacteria and protozoan cysts that may be in the water where you travel, hike and camp.


Refine the purification process with the Grayl G3 Plus Replacement Purifier. Designed exclusively for use with the Grayl Filtration Cup, the Purifier has double the filtration media of the standard G3+ Filter. Two layers of 3-part filter material employ a combination of ultra-powdered activated carbon, which sifts out more impurities than standard granulated or block carbon, a charged-ion mesh, which acts essentially like a magnet to pull pathogens out of the fluid, and an antimicrobial agent to inhibit the growth, between uses, of bacteria, fungus, mold and mildew. Designed for water sources with more potential contamination than the Filter, it will remove all the same common contaminants like lead and arsenic, many industrial and pharmaceutical chemicals, and impurities like sulfur and chlorine, along with 99. 999% of bacteria, protozoa, and viruses. With the additional media, the Purifier takes 30 seconds to process 16 ounces, but similarly lasts up to 300 uses, for 40 gallons of pure, potable water.
