UltraPress

Unlike standard filters that primarily remove sediment and bacteria, the UltraPress is a purifier. This means it is designed to remove viruses, protozoa, and bacteria, providing a higher level of protection against waterborne pathogens.

It is designed for simplicity. You fill the outer shell with untreated water, insert the inner press, and push down using your body weight. The entire process takes about 10 seconds to purify the water.

It is effective against most freshwater sources, including rivers, lakes, and streams. However, it is not designed to remove chemicals, heavy metals, or radioactive materials, so you should avoid water sources near industrial or agricultural runoff.

The press time will gradually increase as the cartridge reaches the end of its life. When the press time exceeds 25 seconds, it is a clear indicator that the cartridge needs to be replaced to maintain effective flow and purification.

Maintenance is minimal. After use, ensure the cartridge is completely dry before storing it for long periods to prevent mold growth. The bottle components can be hand-washed with warm, soapy water, but the purifier cartridge itself should never be washed with soap.
