Three of the Aquamira Frontier Filters arrived earlier this week. I bought them as a backup, and to put one each in our BOBs. Here is an exert from Aquamira’s web site:

The Frontier Emergency Water Filter System is ideal for hiking, travel, and emergency preparedness. It is the perfect addition to your 72 hour emergency kit. One unit will filter up to 20 gallons (75L) of water. Tests indicate that the Frontier Filter will remove 99.9% of Cryptosporidium and Giardia. The Frontier Emergency Water Filter System is also easy to operate, just attach and expand the straw, submerge the filter end into the water source, and drink through the straw.

Ultra light and compact, the Aquamira Frontier Emergency Filter System weighs less than one ounce and easily slips into a day pack, shirt pocket or travel luggage and is always ready when you need it. The Frontier Filter is the ideal alternative to heavy, bulky and expensive pump filtration units when space and weight are primary factors. Activated carbon helps reduce waterborne chemicals and improves water taste. Use the Frontier Emergency Water Filter System to drink from any bottle, cup or directly from water sources.

I have not used this yet, and don’t intend to unless an true emergency comes up. I do not like to use, then store, then reuse water filters. Especially something as small as this. Back of the packaging states this filter will remove pathogens and contaminants up to 3 microns. This is not very good considering Giardia and Cryptosporidium are smaller than that. The Katadyn Vario filter can filter something as small as 0.3 microns. In an emergency I will take whatever is available, and for it’s size and ease of use the Aquamira Frontier “straw filter” cannot be beat.
