Aquamira Frontier Max Features The Aquamira Frontier Max is built to accept any Series IV filter cartridge so the same compact housing can be reconfigured for emergencies international travel or extended backcountry excursions depending on what the water quality demands. Quick connect fittings let it plug directly into hydration packs or inline systems without replacing existing connectors which saves time and gear weight on the trail. The filter is also compatible with all Aquamira pressurized reservoirs enabling pressure-assisted filtration when gravity alone is not practical. Made in the USA the filter media is paired with Miraguard Antimicrobial Technology to suppress microbial growth inside the cartridge over repeated use. At roughly 1 oz the Frontier Max barely registers in a pack yet delivers lead free BPA free chemical free and iodine free filtration that travelers can rely on in questionable biological or chemical water conditions. A patented bite valve can be plugged directly into the unit instantly converting it into a straw filter or gravity-fed system depending on the situation. This versatility means one small component covers several use cases from sipping straight from a stream to filtering a full reservoir overnight. The Black and Gray Frontier Max is a practical multi-purpose addition to any hiking travel or emergency preparedness kit.
