5.0 out of 5 stars Great ultralight one-person filter / backup unit, October 8, 2008
This review is from: Aquamira Frontier Pro Water Filter with Replacement Bacteria Filter (Sports)
Despite a lack of reviews when I purchased this unit, I decided to risk the $20 due to its novel design. After a couple of trips, I have to say I'm impressed. I'll be taking the filter with me on future trips.

If you're into ultralight backpacking or simple day hikes, this filter could save you a lot of weight. It screws onto any standard soda/pop/water bottle (think Coke, Sprite, Aquafina, etc.) and you bite/suck through the nozzle (like a CamelBak) to drink; the water is filtered between the bottle and your mouth.

I coupled the filter with a 1.5L Smart Water bottle (available at most grocery stores) due to the Smart Water's unique size/shape combination, which makes it easier to carry and squeeze. The system acted as an excellent backup unit during my trips. I just filled the bottle directly from the water source, screwed on the filter, and drank. Much easier than pumping.

The unit is also supposed to work with the included straw (for drinking directly out of water sources) or with hydration packs (in place of a regular bite valve). I have not tried either configuration, so I can't attest to their effectiveness.

+ Works like it's supposed to
+ Small and very light
+ Low-cost
+ Fits onto any standard soda/pop/water bottle
+ Stretchy silicone/rubber neck keeps cap in place while closed and safely attached while drinking
+ Entire thing floats if accidentally dropped into water
+ Comes with several replacement pre-filters

- Non-replaceable filter cartridge (you can buy a whole new one for $20, but that creates unnecessary garbage)
- Flow rate isn't terribly fast. It feels like a slower CamelBak, and you might have to start squeezing the bottle as it empties.
- Only practical for one person (unless you don't mind sharing)

Things to watch out for:
* To increase filter life, make sure you use the included pre-filter
* Leaks when used with soft-bodied Platypus bladder-bottles (NOT the same thing as hydration packs; these soft "bottles" are basically small plastic bags with integrated water bottle spouts). The filter screws on, but not tightly enough to create a vacuum seal. This makes drinking very difficult and gets everything wet. I had no such problem with regular, hard-bodied bottles.
* Long-term reliability/flow rate is uncertain due to a lack of reviews.
* This unit does not filter viruses -- no pump/mechanical-action filter does except for the First Need series. You'll need chlorine tablets if this is a concern to you, though it should not be in most North American waters.
* This will not work with Nalgenes (even narrow-mouthed ones), Kleen Kanteens, or SIGGs.

All in all, I love this little thing and will be taking it with my as a backup filter for future trips. It's great if you're camping near a water source and don't want to have to keep pumping for drinking water. Just remember what it's designed for: solo drinking out of a dirty water bottle, not group filtration into clean bottles.

You can use it to filter into clean bottles:
Fill up contaminated bottle, attach filter, hang upside down
be sure to remove the bite valve and it will drip out fresh water into a clean container.

Thank you for a good review. If you have reason to be concerned about bacteria or virus in the water (any natural source may have dead critters or live ones defecating upstream) you can add a SterPEN to your kit. Filter up a bottle of water to remove particulates and clarify and then use the steripen on the filtered water to disable bacteria and viruses.
