Excellent filter system for personal use
I've never used this type of filter system before, but have had zero issues with it on two trips so far and 2gal through the filter. Did buy some extra 32oz bags as the 16oz that comes with the filter is small. I can fill a bag and filter a 32oz Nalgene bottle full of clean water in under 5 minutes, can't ask for much more than that from something this light and small. It's perfect for personal use on day hikes or backpacking, and can be easily set up to gravity filter too. Tip: When filling the Sawyer bag first blow into it and inflate the bag, then hold it open at the seams when filling so it doesn't collapse in on itself. Lots of good usage tips on Youtube as well.
Lightweight, always works, our go-to filter
We have used several of these, including six weeks on the PCT through Oregon. The Sawyer mini always works and is the lightest filter solution out there. The bag is not the most efficient way to use it. We just keep the Sawyer mini on a dirty water bottle, take it off for easy filling, and squeeze. Smart water bottles work best, very durable-- they last us more than a year. Backpacking in the Tetons, the Olympics, the Cascades, and the Andes these are our go-to filter. Never had one fail. Backwashing will give them a new lease on life. If there are more than two of us on a trip, we take an extra filter. Speeds up the morning and evening fills.
Great Depending on Use
Don't expect the performance from this smaller version that you get out of the regular Sawyer. Of course the flow rate is less. If you squeeze the bag harder you will just break the bag. I use this on weekend backpacking trips where I am not on a timeline. Cause if you are in a hurry you will be angry with this one. I bought mine with some extra 64oz bags. Cause the 16oz that comes with it is too small. Set up a gravity system and eat a snack or dinner and let your water filter. There are plenty of videos on how to do it.
Good choice for solo hikers
I used the Sawyer filter on a section of the John Muir Trail. The weight is ideal for solo hikers who prefer filtration over options like tablets and Steripens. However, it's tedious to use. The small-mouthed, collapsible bags are very hard to fill unless you have a fast-moving stream. I'll take a solid water bottle or use a cup next time. It also gets tedious sucking through the "good" end or squeezing the bag to force out water. For a group, I prefer the Platypus Gravityworks, where its extra weight is amortized over the group, but for solo trips, I'll take the Sawyer again.
Always handy, company w/ great philanthropy
This is a revolutionary product that doesn’t need an introduction, but I wanted to refute some of the negative claims. My bag did burst while I was backpacking and I lost 30 ounces of water on a tough stretch….i was devastated and learned not to rely on that bag. Instead I would use a platypus bag. The reason I wasn’t too upset is it fits the standard water bottle thread so I continued to use it on my trip. Just stay informed and prepare to purchase a different bag. Over three days I didn’t have to backwash the filter as it kept flowing freely…despite some very dirty water sources
Very versatile
This filter can be used as an inline, gravity, or pump filter. We actually use them in all those configurations. Screw it to the top of an empty 20 oz bottle, and you can top off at any water source. Connect it to spare water bladder without a top cap for gravity filtering while you set up camp. If you want a lot of clean water fast you just need to connect it to output hose of a siphon pump from the hardware store (5-10 dollars). The one drawback with this filter is that it has minimal effect on improving the taste of the water. In my opinion only a ceramic will get that done. I have owned the MSR Miniworks for a few years, but wanted an option that would serve for both pump and gravity. The sawyer did way better than expected, and now has a permanent place in my bag.
Works but sooooooo slow
My experience is mostly in and around the florida Everglades- so tannic swamp water- and your mileage may differ. But even right after flushing and cleaning, I timed it on our last trip and it still takes 5 minutes to do 16 oz of water, or about 10 min per liter. Didn’t work any faster with super clear pure spring water further north. Plus the threads never really lined up with the pouch, the pouch is hard to scoop water with, and the gasket keeps falling out. It works, but I’d only recommend for very patient people with already pretty clean water or for emergencies.
Filling troubles
I used this last week in the Sierras. It is VERY hard to fill the bottles in streams. Almost impossible and very frustrating, especially with the snow pack this year. The water is freezing cold, and fast moving at 9,000 feet. I had to borrow a wide mouth bottle to get water from the stream while balancing on rocks, transfer that water to the Sawyer foldable bags, and then filter into my hydration bladder. If these fit a wide mouth foldable bottle I would be a happy camper/backpacker. I LOVE how packable, and ultra-light this product is. Fits in my outside pocket for easy access. Easy to drink, straight from the filter, while on the trail.
Great filter
I have used a Pur Hiker for many years, and it worked ok. However, it is not the fastest pump, is pretty heavy, and replacement cartidges tend to be expensive. This little (and I emphasize little) works great. I took it on a recent trip to the Superior Hiking Trail and used it to filter water from a river, a stream with little more than a trickle, and a lake. It worked well for all three cases. The only trick to being efficient is to get the filter bag filled up. It is a heavy gauge plastic that tends to collapse flat. Getting a bit of water in it and then opening the bottom of the bag tends to make this easier. The filter is very easy to backwash using the included syringe. My only suggestion would be to purchase a larger one liter bag, as the included 1/2 liter is pretty small, especially since it is tough to get the whole bag full.
Get the Squeeze
I picked up the Mini a couple of years ago for personal trips. I chose this over the Squeeze because of the price and weight, but it filters so incredibly slowly. Over the past weekend, I was backpacking with someone using the regular Squeeze, which has a higher flow rate when gravity filtering than the Mini has when squeezing. While this surely does the job and is easy to backflush, I would highly recommend picking up the Squeeze over the Mini. It filters easily more than twice as fast. I would use this for weekend trips, but I plan on thru hiking the Colorado Trail this year, and can not put myself through the pain of filtering with this day in and day out for a month straight. Again, this works, but I will be picking up a Sawyer Squeeze before my trip, as it is clearly worth the extra ~1 ounce.
