The Aquamira Bacteria filter is the ideal choice for water filtration when in the out of doors. This filter meets US EPA Purifier Test Standards for the reduction of bacteria and protozoans in EPA Type-I test water for 1000 gallons of use. It proudly boasts a flow rate of up to 800 ml/min for immediate thirst protection.
Aquamira Series IV connectivity allows you to customize any Series IV system (such as the Frontier Max) for use in high-impact activity in the backcountry. The ultralight cartridge dramatically extends your filtration capabilities with less than 1 oz. of added pack weight.
