User Review: Aquamira Frontier Pro Filter
Price Paid: $19.99
This filter really is a light packer's dream. Fits in the palm of your hand and will filter up to five hundred gallons, and fits on the top of any cheap plastic water bottle or collapsible Platypus bottle.
I used this filter on a thirty miler from Idyllwild, CA, to Cabazon on the Pacific Crest Trail. The first half of the trip had quite a few clear running streams. The filter worked great with included straw to suck water straight from the stream. And after topping of my bottle in the stream, the filters rubber bite valve kept it from leaking in my bag.
On the down side of Mt San Jacinto going into Cabazon the lack of moisture is immediately evident near the bottom I had run out of water and searching the dried stream beds found and small pool of water complete with algea, tadpoles, and water skippers. Using my back-up iodine tabs the filter didn't clog and made the water taste great.
Only two problems i had were the straw for water bottles didn't seal well on the filter and let air bubble past slightly and the tightly woven cotton prefilter makes it difficult to suck.
Buy one, it's worth it.
