Water Purification Systems

Exstream Water Technologies, a Katadyn company, manufactures EPA-registered personal water purification systems that eliminate pathogenic cysts, bacteria, and viruses from untreated water. The Exstream personal water purification systems utilize a multi-stage, modular system. At the heart of the system is a ViruStat^® microbial water purification cartridge. The ViruStat uses PentaPure^® penta-iodine resin to kill over 99.9999% of waterborne bacteria and 99.99% of viruses. The ViruStat employs a patented ion-release technology that dramatically reduces residual iodine, and special coconut-carbon scrubbers that further minimize any residue. The ViruStat cartridge is preceded by a replaceable 1-micron filter that removes more than 99.9% of pathogenic cysts. A prefilter is installed below the cyst filter to remove sediment and organic contaminants and thereby extend the life of the cyst filter. The ViruStat cartridge, cyst filter, and prefilters are all replaceable (see below).

Purifiers have an advantage over water filters in that they also remove viruses, such as Poliovirus type 1 and Rotavirus Strain SA-11, that can cause hepatitus, meningitis, and polio. Most wilderness medicine professionals now recommend treating water for viruses as well as bacteria and cysts. The Exstream water bottle design has the advantage over pump-style water filters and purifiers, in that they don't require stopping, unpacking, sorting hoses, and pumping the water into a separate container.

The Exstream products below are full water purifiers using the ViruStat system. Each delivers 100 liters (26 gallons) per replaceable cartridge (estimated 4-6 weeks when used exclusively). The EPA registration number is 35917-3-72228.
