Compact and Capable


When I first held this filter, I was surprised by how small and lightweight it felt—barely 2 ounces. Its compact design makes it perfect for fitting into any hiking or camping setup, whether you stash it in a side pocket or attach it to a hydration pack. The filter can screw onto most disposable water bottles or work inline with a hydration bladder, making it incredibly versatile.


In terms of performance, it’s reliable and fast. With a flow rate of 1 liter per minute, I didn’t have to wait long to fill my bottle directly from streams and lakes. It’s especially useful on longer hikes where carrying water isn’t practical. The filtration system blocks bacteria and protozoa with its 0.1-micron membrane, and I noticed the water tasted fresh every time.


What I love most is how durable it feels despite the tiny size. The included syringe makes cleaning easy—just backflush it to restore flow rate. It may require occasional maintenance, but it’s built to last, with a lifespan of up to 100,000 gallons. For such a small piece of gear, it offers peace of mind on every outdoor adventure.

What Others Are Saying


I wanted to combine my opinion with others, so I searched for user reviews from around the web. The feedback was mostly positive, with a few shared challenges. Many hikers, campers, and preppers love how lightweight and easy it is to use on the go. However, some pointed out that it requires frequent cleaning in muddy water and isn’t ideal for large groups.


Pros

  • Lightweight and ultra-portable for any outdoor trip

  • Filters bacteria and protozoa effectively, improving water taste

  • Works with multiple containers: bottles, hydration packs, and included pouches

  • Affordable and offers long-term durability with a lifespan of 100,000 gallons


Cons

  • Frequent backflushing required to maintain flow rate

  • Can clog quickly in muddy or sediment-rich water sources

  • Not suitable for filtering viruses, so it’s limited in certain environments

  • Some found the included squeeze bag less durable over time


In real-world situations, this filter excels at keeping adventurers hydrated without carrying heavy water. Whether you're hiking remote trails or preparing for emergencies, it provides peace of mind knowing you can access safe water. While it may require regular maintenance, it’s worth the effort for the convenience it offers.

Who Should Consider This Filter?


If you love hiking, camping, or just spending time outdoors, this filter can make a big difference. I’d recommend it to anyone who wants to travel light without sacrificing water quality. It’s also great for preppers or those building emergency kits—having access to clean water during unexpected situations offers peace of mind.


I found it especially useful on solo hikes, where packing light matters. Families or groups might find it a bit slower, but for individual use, it’s perfect. If you’re after a compact, reliable way to filter water, this is a smart investment for your adventures.


Is It Worth the Money?


When it comes to value, this filter offers a lot for a little. At around $25, it’s one of the most affordable water filters designed for outdoor use. Compared to pricier options, it holds up surprisingly well in terms of functionality and longevity. I appreciate that it can filter up to 100,000 gallons without needing a cartridge replacement—many other filters on the market don’t come close to that.
