The replacement purifier cartridges for the UltraPress™ are built to last 300 cycles, equivalent to 40 gallons (150 liters) of water purification. However, if you're purifying water with high amounts of silt, sediment, or tannins, the cartridge's lifespan may decrease. As the cartridge nears the end of its life, the press time will increase. Once the press time hits 25 - 30 seconds, it's time to swap out the cartridge. Even as the press time goes up, the cartridge still offers protection. Key features include the removal of a wide range of waterborne pathogens such as Rotavirus, Hepatitis A, Norovirus, Giardiasis, Cryptosporidium, E. Coli, Cholera, Salmonella, and Dysentery. It also filters out particulates like sediment and microplastics, along with many chemicals, pesticides, and heavy metals. Moreover, it enhances the taste, smell, and clarity of the water. In terms of technical specifications, it uses ion exchange and ultra - powdered activated carbon technology. It's antimicrobial and chemical - free. The cartridge measures 2.9 inches (7.3 cm) in height and 2.7 inches (6.7 cm) in width and weighs 2.8 ounces (80 g). It can remove 99.99% of viruses, 99.9999% of bacteria, and 99.9% of protozoan cysts. The activated carbon effectively adsorbs chemicals, pesticides, heavy metals, flavors, and odors. It has a fast flow rate of 10 seconds per 16.9 fluid ounces (3 liters per minute). The cartridge is rated for 300 cycles (40 gal. / 150L), and you should replace it when the press time reaches about 25 seconds or three years have passed since first use. When stored properly, an unused and airtight cartridge has a shelf life of 10 years. It's made from BPA - Free ABS food - grade plastic and food - grade silicone.
Using your Grayl UltraPress Purifier Cartridge is easy. First, make sure the cartridge is properly installed in your UltraPress. Then, fill the press with water from your source. Press down on the unit, and clean, purified water will come out. It's that simple! When it comes to lifespan, remember that the cartridge is designed for 300 cycles or 40 gallons (150 liters) of water. But if you're using it to purify water with a lot of dirt, silt, or tannins, it might not last as long. Keep an eye on the press time. Once it takes around 25 - 30 seconds to press out the water, it's time to get a new cartridge. Even as the press time gets longer, the cartridge still protects you from harmful stuff. To maintain your cartridge, store it in a cool, dry place. If you're not using it right away, keep it in its airtight packaging. An unused cartridge can last up to 10 years when stored properly. Also, make sure to replace the cartridge every three years, even if you haven't reached the 300 - cycle limit. This will ensure you always have clean, safe water.
