Product description

HydroBlu Sidekick 3-Stage Straw Water Filter for Camping, Backpacking, Running, Travel, and Emergency Preparedness

Whether you are hiking, camping, backpacking, or just need a solid backup water filter, the Sidekick 3-Stage Straw Water Filter by HydroBlu is your perfect adventure companion. The 3-stage water filter provides the most robust filtration of any straw style filter.
The easy to use Sidekick protects you from bacteria, chemicals, heavy metals, and other contaminants. Large sediment is blocked with the cotton pre-filter membrane, increasing the longevity of the filter. Nasty chemicals and heavy metals are adsorbed by the Activated Carbon Filter. Activated Carbon removes lead, iron, cadmium, nickel, chromium, and zinc along with chlorine, pesticides, herbicides, gasoline, and diesel fuel. Once the pre-filter and Activated Carbon filters have reached their life expectancy of 50 gallons, they can simply be replaced with the extra end cap filter which is included. Finally, the Ultrafiltration Hollow Fiber removes 99.999% of bacteria. Hollow Fiber is made of dozens of tubes that have microscopic holes (0.1 microns) that don’t allow bacteria to pass through, while allowing clean water through by size exclusion technology
