How does it work?

The UltraPress Purifier uses electroadsorption, ultra-powdered activated carbon, and silver treated zeolites. Unlike standard mechanical filtration, the UltraPress Purifier Bottle is powered by a patented electroadsorptive media capable of removing submicron pathogens and inorganic contaminants. With [ONE PRESS], electroadhesion and ion exchange create a powerful submicron trap for pathogens (viruses, bacteria and protozoan cysts). Additionally, the purifier media contains many embedded layers of ultra-powdered activated carbon which create a large surface area for removing toxins like chemicals and heavy metals. Silver treated zeolites, a natural antimicrobial, inhibit growth and keeps the purifier fresh between uses.

Simply separate the outer and inner chambers, fill the outer chamber with questionable water, and then push the inner chamber back into place. The dirty water is filtered as it flows into the inner chamber!

How do I know when to change my filter?

The filter collects debris from water that passes through it. When there are too many of these particulates in the filter, it will become more difficult to force water through. When it takes about 25 seconds to filter the full bottle, it’s time to change your filter – or 3 years after first use if that’s sooner.
