User Review: Aquamira Frontier Pro Filter
Price Paid: $18
I have now used my Aquamira Frontier Pro Filter for about 300 gallons worth of filtration. It's easy to use, gives me acceptable water quality, and looks like it's going to last for the full 500 gallons the manufacturer claims.
Therefore, I officially pronounce it hot stuff. I use two units, one set up as a filter on the drink tube of my hydration bladder for "dip 'n' go" use, and the other as the working part of a gravity feed purifier system (If you pull off the bite valve there is a coupling you can rig to a tube.). The Frontier Pro works well in both configurations.
I do however have two gripes, both little ones. One is that the bayonet fitting that you use to attach the filter to your hose is smooth bore on the outside. This makes it prone to detachment when attached to a hydration bladder tube. (I fixed this with Superglue.)
The other is that the manufacturer could easily put in better instructions that would alert the buyer to the gravity feed usage.
Other than that, it's a thru-hiker's dream. It works, it's light, and it's dirt cheap compared to the competition.
