Sawyer Products SP128 Water Filter - 0.5L

Got it delivered much before the expected delivery date. Product is fantastic. The seller sent it well packaged. I am using the filter. The flow was not there at the first time I tried sucking water through it. Just gave a min for the fibers inside to soak, and then it was a normal flow. Felt like drinking water from a wide straw. Its definitely effective. I am going to test the filter to purify muddy dirty water soon and will update on how well the filter purified it. Few people here complained that it wont filter out the viruses and its only 0.1 micron filter. well, Viruses are pretty rare in the water that you drink everyday. roadside hotels, certain places where the source of water is suspicious, this filter is more than sufficient to guarantee that u will be safe drinking that water. Unless u r drinking water from roadside drainage or some extremely dirty stagnant water, u don't really need a filter which can remove the viruses. If u are still concerned about the viruses, u can order water purifying pills available on amazon. the seller is Hind-Pharma and their tablets are absolutely amazing. Use the sawyer mini, remove all the bacteria and other nasty stuff from the water, drop a tablet in the water, wait for a while for it to work and drink the water. Its an absolute must for everyday use, during travelling, etc. One might feel awkward using it in India as people will definitely stare at u when u are using it, but hey, I don't care. My health is imp to me and clean water is must. I don't wanna be sick just because I drank some supposedly clean water. Its in my bugout backpack now. Ill order another to carry with me for everyday use

Awesome product. Back wash required after very long use. Though water bags appears crumpled and would get torn after one two months regular use, still product itself is very rugged and appears will stay for 1 million gallons=3*10,00,000 litres which is vfm!!! Price of 04 set is very low abroad (amazon.com) however compared to that being sold in amazon.In. If the same price is made available without the exuberant delivery charges (as auth. Distributor exists in India so no need to call in to stocks from US after paying delivery) if the same at the same price can somehow be made available. Very good for sales personal and people always on the move, client visit etc,as water at different places, road side, hawkers or readily available on the go is questionable. So even if you are not immediately going on a mountain hike, still the product is useful in the city!!

See all the reviews and videos online and you'll know that this is the best filter for all kinds of bugs in your water (except viruses). Sawyer does make a 0.02 micron filter for them pesky viruses too - this one is.0.1 micron, for everything except viruses. Anyway, this is the lightest, smallest effective filter and its flow was fast after my third squeeze through it (the first couple of squeezes are slightly slower until the fibers get fully saturated with water). And after some more use, the flow gets even faster. Yes, it is much slower in a gravity set-up, but use the Sawyer Squeeze for that (instead of the Mini). Flow looks to be about the same rate as when you pee really hard ;) Can fill up a liter in about a minute, maybe 1.5 minute. And you can fit this directly onto most popular one liter bottles, so if you don't like the water pouch, then you can use a regular bottle. Backwashable filter is absolutely essential in my book (for cleaning, longevity, etc.). Also, this is an absolute 0.1 filter (meaning that no hole is larger than 0.1 micron). I don't trust the electrostatic or other charge-based filters which claim to filter everything because their assumption is that all bugs carry a positive charge (and the bugs they test DO carry positive charge)... plus the charge polarity filters I'm not sure will catch everything in real life scenarios. And other filter types require replacing frequently otherwise filtration suffers (and bacteria may actually grow inside the filter!). Also, I saw a video where numerous Sawyer filters failed in some village (I forget the location). That "analysis" has since been shown to be faulty by real, controlled tests - there is also a paper published by Tufts University that proves that the Sawyer filters do what they say. Also, make sure you don't expose this (or ANY) water filter to freezing weather - because of the way water expands/contracts, freezing will damage filters (even if the filters look okay on the outside). In freezing weather, they say to carry your water filters in your pocket and at night put in your sleeping bag - even easier to do with this mini size. Also, on flights can't check it in; take in your carry-on bag. Update: To all the people looking for fail safe option, I've been using the Sawyer Mini first, and then a second pass with this SteriPen during travel in India. Drank about four liters of Indian tap and well-water every day for total of ten months using my system and have not gotten sick... if that's not proof, then I don't know what is!

Good quality piece, not a cheap copy thankfully. Used it on treks, it's a compact and extremely useful thing to have.

Excellent unit. I love the fold able bottle that comes with it, removing the need for me to purchase another such item for my travel kit. The filter itself is very useful and work very well. The included straw and the syringe are both robust and well designed. I have no complaints and the Sawyer kit is a well recommended item in every survival kit. I am happy to have this with me.

From the health point of view, it's impossible for a commoner like me to say whether it's bad for your health. But it's a great product. Only drawback is that the water packet doesn't have provision to hang, hence you will have to hold it for a while if you are trying to fill up your bottle. One advice: Dry the packet from outside with a cloth before you fill a bottle. You don't want dirty water dripping in your bottle with the filtered water!

Highly effective in its task. Used it on a multiday trek to the Himalayas and used it for filtering water from the rivers for cooking and drinking purposes. Thankfully not a single water related health problem. Would highly recommend for carrying along outdoors.

The best portable water filter ever. It completely eliminates the need to buy bottled water on your trip. 0.1 micron filter, with a claim of filtering 100,000 gallons= 3,78,541 Litres. So if you drink 4 litres everyday from the Sawyer MINI then it will last you for 259 years. After having a look at Sawyer MINI, the lifestraw filter seems like a waste of money as it comes with a 0.2 micron filter and can filter only around 1000 Litres (264 gallons). I bought this filter for my motorcycle rides, so that I can drink safe and pure water everywhere. In India and even abroad there is no other portable water filter that can come even close to the Sawyer MINI for the price and purification that it offers.

What a great little product, small lie weight and practical, that's what you want any day of the week on the trail. The only downside is, I found the squeeze bag (16 oz) a little too small for my liking, constantly need to fill up and filter. A large squeezy bag would be ideal.

I am very happy with my purchase!

Ce filtre est surprenant. Il filtre a 0.1 microns alors que des filtres a 350 euro sont encore a 0.2 microns Une capacite de filtrage hallucinante (378,5 m3 ca represente une duree de vie de plus de 378 000 litres...). Il y a un pas de vis qui permet de visser dessus des bouteilles de type Coca/Soda et ces bouteilles, vides, se compriment super facilement dans un sac. Cela permet donc d'emporter une bouteille qu'on ecrase bien, et on peut visser le filtre dessus sans probleme. Apres chaque filtrage, utiliser un peu de l'eau filtree pour nettoyer le filtre avec la seringue fournie. En mecanisme je l'utilise avec deux poches Platypus (celles que l'on peut ouvrir au sommet, et qu'on peut nettoyer facilement puisqu'on peut glisser la main dedans pour bien nettoyer dans les coins la poche interne). Dans une premiere poche de 2L je recupere l'eau. Le tube de la premiere poche va jusqu'au filtre Sawyer et sa sortie va dans une seconde poche de 2L. En fixant sur un arbre la premiere poche et par simple gravite, en 10 minutes je filtre 2 litres d'eau sans aucun effort. Le filtrage retire protozoaires et bacteries, et il ne me reste plus qu'a faire bouiller les 2L pendant 3 minutes en faisant 1 litre a chaque fois, et je depose chacun de ces litres dans une gourde 1L pour un emport total de deux litres : 1L de chaque cote du sac pour equilibrer la charge. Permet de se construire facilement avec du Platypus un mecanisme de filtrage par serie de 2L. Une duree de vie incroyable et un filtrage vraiment impressionnant. Attention : ne supporte PAS du tout le froid. Il faut absolument preserver le filtre du froid donc a conserver dans une poche interne de blouson pendant l'hiver pres du corps et a garder au chaud. Ne pas laisser le filtre tomber en temperature negative, car il est alors "foutu". Si vous randonnez l'hiver il faut faire attention sur ce point et proteger le filtre.

Amazing filter at an amazing price. So far I have only used this filter for a canoe camping trip for the three days in the backcountry. Devised my own gravity feed setup using a backpack hydration bag to collect lake water, through the filter down a second tube into our 15L folding water container...WOW!! Hang 2L walk away, turn around in 2-5 min and clean drinking water. Filled 10L in no time flat for the family's drinking requirements for the whole day. Backflush, and it is good to go again. Don't know how I will keep track of when I reach 100,000L, but I don't think that will be of concern. Haven't used it with the squeeze bag yet... I am sure it works like a charm. Fast enough flow that I could bring the backpack bag dip it over the side of the canoe to fill, then use the filter inline in the drinking hose for clean water. Storing in our home emergency kit when not camping. Have used the pump kind with replaceable filter and this thing kicks its output hole :) SOOOOO easy and convenient and small, at this price just buy one in case you might need it while camping or for home emergency kit.

UPDATE: So I recently added the CNOC Vecto 2L bladder to this rig and got rid of my Survivor collapsible canteens. I don't think I'll be going back. The Vecto has a large opening to fill, and a 28mm bottle cap to dispense. The Mini screws on perfectly and now I can filter 2L at a time with no issues. Loving this. I also have gotten rid of all my Nalgenes from my backpacking/camping setup. I use them for the office now. I have replaced them with Smartwater bottles. The SW bottles weight less than 2 ounces each, cost $1-2 each and fit the Mini. I have also found I can get two 32 oz SW bottles into a single water bottle pocket on my pack. That means I can either carry 4 liters of water without affecting my internal storage. I have come to really value that decision. When a SW bottle wears out or breaks, I can replace it at pretty much any grocery store for less than $2. ORIGINAL REVIEW (May, 2017): Did some back country camping this past weekend and took the Sawyer Mini out with me for the first time. Reviews on it were good and I was looking for ways to cut down on weight and footprint on my old filter system (a pump). The mini is excellent. I've seen a few reviews complaining about the bag it comes with and the time it takes to squeeze "x" amount of water through it. All I have to say is, yes the bag is too small. 16 oz is kind of lame. The quality of the bag? Seems decent enough. I'll end up replacing it anyway with a pair of Survivor Filter collapsible canteens (32 oz each). As far as the filter goes, I tried it on just some regular old tap water to function test it and get familiar before taking it out. I filtered two liters of water through it (2 Nalgenes) and then back flushed it. I was shocked to see the brown much it filtered out of the tap water! I may get a second on and just screw it onto a SmartWater bottle for drinking at work! The system was easy to use. I don't know what kind of rush others are in when backpacking, but I'm not. I move at my pace and take my time. i'm not in a race when I'm backpacking or camping. I don't mind taking a couple minutes to filter some clean drinking/cooking water. The Sawyer Mini works great. I have zero complaints. I appreciate that it comes with the syringe to back flush it and keep it working well. The 16 oz bag is too small, but it works, and unless you're Hulking out on the thing, it should last just fine. That's one piece I'll upgrade, but the filter alone is well worth the cost of the set.
