For backpackers, hikers, and campers, the Sawyer MINI is a tiny water filtration device that won’t take up any space in your pocket or pack. It’s extremely light at just two ounces, but it’s a powerful tool that will filter out over 99% of bacteria and protozoa from water sources you find on the trail.

Like its big brother, the Sawyer Squeeze, the MINI has a 100,000-gallon lifespan with no cartridges to change. Just backflush the filter when the flow rate starts to decrease and it will work like new again. The MINI filters down to 0.1 microns and can be used in many different ways. You can drink straight through it, use it in-line for a hydration pack or a gravity-fed filtration system, or you can use it as a simple filter straw and drink straight from the water source.

Unfortunately, the MINI doesn’t have as much flow as we’d like and we sometimes found ourselves struggling to get enough water through it.

Fresh drinking water is essential. This water filtration system ensures you will never run out as long as there is a nearby natural water source. It can filter out bacteria, protozoa and microplastics.

Faster and more efficient than pumping or waiting for chemical treatments, the Sawyer Squeeze System offers on-the-go hydration at a good flow. This product is long-lasting, affordable, reliable, cleanable, and very user-friendly.

But Sawyer was way ahead of me — 15 years ahead, to be precise. In 2008, the brand started its Clean Water for All initiative, which provides Sawyer filters to developing countries around the world. And the company spends 90% of its profits funding it.
