Grayl - 16.9oz UltraPress Purifier - Covert Series

The Grayl UltraPress Purifier uses a combination of electroadsorption and ultra-powdered activated carbon to remove pathogens. This technology is effective against viruses, bacteria, and protozoan cysts, including Rotavirus, Hepatitis A, and Giardia. The purifier works by filling the outer container with water and pressing the inner container down, forcing the water through the filter. This process not only removes pathogens but also filters out sediment, microplastics, and adsorbs chemicals like PFAS and VOCs.

The Grayl UltraPress Purifier is designed for global use, providing protection on all seven continents. Its compact design fits easily into any pack, making it ideal for travelers who need reliable water purification from diverse and challenging freshwater sources. The purifier's ability to remove a wide range of pathogens and chemicals ensures safe drinking water, whether you're hiking in remote areas or exploring urban environments.

The One-Way Valve in the Grayl UltraPress Purifier allows users to add electrolytes and drink mixes directly into the purified water. This feature is particularly beneficial for athletes or hikers who need to replenish electrolytes during strenuous activities. By enabling the addition of flavored liquids, the valve enhances the versatility of the purifier, making it not just a water filter but also a hydration tool that can adapt to various nutritional needs.

The cartridge of the Grayl UltraPress Purifier is rated for 300 cycles, equivalent to 40 gallons or 150 liters of water. You should replace the cartridge when the press time reaches approximately 25 seconds, indicating that the filter media is becoming clogged. Regular replacement ensures optimal performance and safety in water purification.

While the Grayl UltraPress Purifier is highly effective against many contaminants, it is not designed for desalination. This means it cannot purify saltwater, making it unsuitable for ocean or brackish water sources. Additionally, heavily polluted industrial water may require additional treatment methods beyond what the UltraPress can provide. It's important to assess water sources carefully and use the purifier within its intended capabilities.

The Grayl UltraPress Purifier stands out for its rapid filtration speed, purifying 16.9 ounces of water in just 10 seconds.
