Aquamira Frontier Pro Filter

The cleanest, easiest, most compact ultralight water filter system in the world

Like no other filter system in the world! The designers at Aquamira have come up with the ultimate pump-free filter system. Aquamira told their designers that there was something missing when it came to portable filtration devices. They wanted a small, compact, easy to use filter that would compete with the “big boys.” No pumps or tangly hoses to mess with, they just wanted the cleanest, easiest, most compact system in the world. With this in mind, their designers considered multiple uses, the prevention of cross contamination, size, weight, ease of use, extended filter life, universal connectivity, as well as “hands free” gravity flow capability in the development of the Frontier Pro filter system. The result is a new concept in ultralight, compact portable filtration that fits in the palm of your hand, which is why they say, “Dump the Pump!”

Connect to almost anything using the universal connectivity system. The Frontier Pro filter will connect directly to any water bottle with a 28 mm opening, such as a Platypus or standard spring water bottle. Using the tube connection feature, you can connect to the drink tube of your hydration system or drink from any open container or water source. Since you drink directly from the unit, there is no chance of confusing inlet and outlet tubes, resulting in possible cross contamination. The Frontier Pro can also be set up in a “gravity flow” mode to filter water unattended while you pursue more enjoyable uses of your valuable outdoor time.

Aquamira didn't forget Miraguard in the Frontier Pro. Since Miraguard suppresses the growth of bacteria, algae, fungus, mold, and mildew in the filter media, you can use the Frontier Pro on multiple outings without worrying about nasty things growing in the filter between uses. The patented Bite Me valve provides drip free easy drinking and the integrated cap and Strap Grip keep the drinking end clean and contamination free.

Technologically Advanced Filter!

Like a Frontier Filter on steroids, the Frontier Pro filter boasts more than double the capacity of the original Frontier Filter, without doubling the size. The ultra-light (2 oz dry) and compact (6.75 in) design is less than half the weight and takes up less than half the space of a typical “pump” type filter system. All of this performance comes in a package the size of a compact flashlight that fits easily into the smallest of pockets.

Two step filtration is the key to making a high capacity filter system so compact and light weight. Increased surface area, flow control vanes, and the addition of our replaceable pre-filter disks allows the Frontier Pro to handle even turbid water without choking up. The replaceable pre-filter disk removes larger water-borne particles that would foul the microfilter quickly. Because extra disks are included with the Frontier Pro, they can be replaced or even “doubled up” to improve the life of the filter. The Aquamira porous plastic microfilter removes 99.9% of Cryptosporidium, Giardia and other contaminants down to 3 microns. Only the finest quality coconut shell carbon is used in the production of the Aquamira micro filter to absorb chemicals and odors and to improve the taste of the filtered water.

The “patent pending” design of the Frontier Pro filter system includes the unique Strap Grip cap system to retain the cap and protect the patented Bite Me valve from contamination, along with providing a sure grip on the filter that fits comfortably in your hand. The filter casings are constructed of high impact FDA grade ABS plastic to assure long life, even in harsh environments. The universal connectivity system allows connection to 28 mm threaded bottles, such as Platypus and other light weight flexible bottles, and to any ¼” ID tube such as hydration drink tubes or the draw tube provided. You will be amazed that a filter this small can do so much.
