Micro Squeeze Water Filter

As an avid outdoor enthusiast, having access to safe drinking water is non-negotiable—it is, quite literally, a matter of survival. I purchased the Sawyer Products SP2129 Micro Squeeze, an ultra-compact and lightweight water filter, as a key component of my emergency kit and backpacking gear. I was looking for a foolproof, high-performance filter that wouldn't weigh me down, and the Micro Squeeze delivered on its promise to provide virtually limitless clean water from natural sources. Experience and Analysis The Micro Squeeze is a marvel of engineering. It uses 0.1-micron hollow fiber membranes, a filtration standard that removes 99.99999% of bacteria (like E. coli and Salmonella) and 99.9999% of protozoa (including Giardia and Cryptosporidium), far exceeding EPA recommendations. The versatility of the system is its biggest strength: you can use it with the included squeeze pouch, screw it onto a standard 28mm threaded disposable water bottle (like a Smartwater bottle), use the included straw to drink directly from a source, or set it up in-line with a hydration bladder. Out of the box, the flow rate is excellent—much faster than its smaller sibling, the Sawyer Mini—making it quick to refill bottles, especially with the 'squeeze' method. While some comparative tests show the original, slightly larger Sawyer Squeeze as having a faster flow rate, the Micro Squeeze hits the sweet spot for weight, size, and efficiency. The included cleaning plunger allows for easy backflushing, which is crucial and will restore up to 98.5% of the filter's flow rate, ensuring the filter's incredibly long life of up to 100,000 gallons. This indefinite lifespan gives unparalleled peace of mind on long trips. Pros Exceptional Filtration: Removes 99.99999% of bacteria and protozoa, meeting or exceeding all EPA standards for safe drinking water. Ultra-Light and Compact: Weighs under 2 ounces, making it negligibly small and light for any pack or pocket. Unmatched Versatility: Compatible with squeeze pouches, standard water bottles, hydration packs (in-line), and direct drinking from a source. Incredible Longevity: Rated to filter up to 100,000 gallons and is field maintainable with the included backflush syringe. Cons Vulnerable to Freezing: Like all hollow fiber filters, it must be protected from freezing, which can damage the fibers and compromise its filtering ability. Slower Gravity Flow: When used in a gravity filter setup, it is noticeably slower than the original Squeeze model. Verdict The Sawyer Products SP2129 Micro Squeeze is, without a doubt, a perfect 5-star product and one of the best value-for-money items in outdoor gear. It offers professional-grade water safety in a pocket-sized package. While you must be mindful of freezing temperatures and should backflush it regularly, the combination of its featherlight weight, multiple-use versatility, and near-infinite lifespan makes it an essential piece of equipment. I highly recommend the Micro Squeeze for thru-hikers, backpackers, international travelers, and anyone building a comprehensive emergency preparedness kit.

Great item for bushcrafters,survivalists,hunters & emergency go-to bags.

I originally bought this for long hikes that I take on a camping trip each year. I've used it on those hikes and it's wonderful and lightweight easy to use. Honestly though I use it more often when I'm mountain biking on local trails. It means I don't have to carry as much water with me because I'm able to filter water as I go and this is much lighter than carrying water

I am not an outdoor enthusiast by any means. But I do believe in being prepared. I was putting together an emergency evacuation Go Bag and wanted a water filter that was reliable and easy to understand how to use. I watched a number of youtube videos and saw that the Sawyer was recommended over and over. Even I can understand how to use it. So I got one for my bag and one for my husband's bag. I practiced with the product and it really is easy. Impressed with how tiny it is, too.

I love this thing. I bought it for backpacking through Sequoia National Park/Forest for a week and it did great. I prefer to use Smart Water bottles rather than the squeeze pouch and just use the filter as a lid to the bottle and drink through the sport cap. Since the filter isn't vented I do have to loosen the cap every time. I drink out of it to let the bottle go back to its original shape, and this starts to create weak points along the creases of the bottle that could potentially cause holes after a week or heavy use. The squeeze pouch is the same way though, and I would make sure to have at least one backup pouch with you if you are going out for longer treks. My biggest issue with this filter is that the gasket gets stuck in the mouth of the bottle or pouch almost every single time and does not seal correctly, taking a few tries of taking it off, realigning the gasket, and putting it back on the bottle. The filter comes with an extra gasket but I do worry that this is a weak point of the filter. I did buy this for longer section hikes but I now pack it with me everywhere with the straw and sport cap in case I get in a pinch out on a day hike and its compact size and ultra light weight with that setup is awesome.

Had a Sawyer Mini. It is now at the bottom of a gorge :(. Upgraded to this as a replacement. Love that it is easy to use. Nice flow. Easy to back flush/clean. Cons are that it can leak if not perfectly tightened on with properly seated o-ring. Make sure to not let it freeze and it will last forever!!!

Been probably 8 years since I bought my last Sawyer. I love them, they last forever. I have probably already ran 10 gallons thru this one since I got it.

Compact water purification item.

リピ 予備として購入。 ミニより濾過速度が早いので助かるがキャップの蓋がすぐ壊れるのでその部品だけ販売してほしい。

I used this on a recent 17 day hike in outback Australia. The filtration system itself worked really well but the squeeze bag failed at the seams around the nozzle on the first use. I tried to do repairs on the track with some tape but it was not salvageable. Unless the squeeze bag is upgraded to something useable and reliable, it would be better not to include this at all in the package.

The Sawyer Micro Water Filter is an absolute essential for anyone who spends time outdoors, travels, or wants reliable access to clean drinking water in any situation. Don't let its incredibly compact size fool you – this little filter packs a serious punch! What impressed me most is its unbelievable portability. It's so lightweight and small, it barely takes up any space in my backpack, emergency kit, or even a daypack. This makes it an absolute no-brainer to bring along on hikes, camping trips, and international adventures where water quality might be questionable. Despite its size, the Sawyer Micro boasts impressive filtration capabilities. Knowing that it effectively removes 99.99999% of all bacteria and 99.9999% of all protozoa gives me immense peace of mind when sourcing water from natural sources. It's incredibly easy to use – simply attach it to a water bottle, hydration pack, or use the included drinking pouch. You can even drink directly from a water source using the straw attachment. The durability and longevity of this filter are also outstanding. With proper backflushing (which is a simple process), it's rated to filter up to 100,000 gallons of water! That's an incredible lifespan and makes it an incredibly cost-effective solution in the long run. Whether you're a seasoned backpacker, a casual hiker, preparing an emergency kit, or traveling to areas with unreliable water sources, the Sawyer Micro Water Filter is an indispensable piece of gear. It's reliable, easy to use, incredibly portable, and provides the vital assurance of safe drinking water. I wouldn't head into the backcountry without it!

Great product to use outdoors, like camping or trekking. Cleans any water source you could find in the outdoor.
