The Aquamira Frontier Pro is the perfect filter for ultralight backpackers and those who just want a little added security.  It's so small it will fit easily in a pack pocket, emergency kit or first aid kit. 

Don't let the size fool you.  The Frontier Pro removes 99.9% of Giardia, Cryptosporidium and other contaminants down to 3 microns.  Activated carbon helps reduce foul taste and smell and waterborne chemicals.  The Frontier Pro also features Miraguard antimicrobial technology to suppress the growth of bacteria, algae, fungus, mold and mildew within the filter media.  Use the Frontier Pro in conjunction with Aquamira Water Treatment drops where viruses or smaller bacteria are suspected. 

The Frontier Pro attaches easily to standard hydration systems or allows you to drink directly from a water source or cup or bottle.  Includes 4 prefilters to extend the filter life.  Filters up to 50 gallons.  Approx 1 1/4" x 6", weighs only a few ozs.  Includes 28mm Thread tube adapter for hydration systems and 12" draw tube.  Retail:  $24.99
