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

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!

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!!

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

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.

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!

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.

This is an amazingly compact and effective water filter. The back wash syringe is in fact bigger than the filter. If you are a trekker/ adventure junkie then its a must have. Even the normal city types can have one while travelling. It's so small that in fact at first you will doubt its efficiency, but it actually is effective. Do backwash regularly.

So, this is probably the best in this class of water filters. I have a LifeStraw, a LifeStraw water bottle, an MSR (I think) travel filter (awful). This Sawyer is the best of them. There is no messing about with it, it just works. It comes with a collapsible pouch, which is nice because it makes it easier to drink from if you squeeze the container. It will also connect to standard disposable water bottles, if you prefer that or happen to have one. It comes with a straw, which is nice, so you can drink directly without the pouch, but you are pretty much lying on the ground to make that happen. One thing about the pouch, because it's flexible, if you submerse it in water, it will collapse and push the air out without taking water in. So, you just have to inflate it with your mouth, and try to scoop water into it. Kind of a pain in the butt. Also, if there is any air in the container when you attach the filter, you can't just drink from it like a straw, because you will just get air. So, bottoms up! I also have a Platypus 2L bag which this does plug into. Not sure if I can use it in-line, but I can definitely use it as a gravity filter with this Sawyer, so that's a nice option. As for flavour, I haven't tried it with really dirty water yet, just clean flowing streams, here in Ontario, but it is delicious. This is the best for the price point.

I'm far from an experienced long range hiker or backpacker. I'm fairly comfortable out in the woods, do about 8-9 miles a day in about 2 hours, and have common sense, but I am not a backwoodswoman (unfortunately). A conveniently-sized filter has been on my "that'd be cool" list for years, and while planning a mountain day hike with my sister I went for it with the Sawyer Mini. This was a 2,500' elevation gain hike that was expected to clock in around 9 miles round-trip, trail reports said the average run time was about 4h 45m. No problem. I'm one of those who needs to hydrate excessively- I routinely go through about 2 liters of fluid on a 9 mile route. My hydration pack takes 2 liters, so I figured I probably wouldn't even need the filter but the trip made a good excuse. I even tossed in a lightweight disposable 28 oz bottled water before leaving our car, thinking "No way is that filter getting used!" Man am I glad I had the Sawyer. My hiking partner is not anywhere near as active as I am, which resulted in hours longer on the trail than expected, and surprise, the route clocked in closer to 15 miles than 9. So we were out there, including a break at the spectacular turn around location, for about 10 hours. The Sawyer performed beautifully. I didn't have to stress about trying to conserve water, which was a real relief on the way back, now knowing how long the route actually was and how fast my partner and I were likely to move. The available watersources were mountain streams on a *heavily* trafficked trail (it was like a traffic jam in sections), so the water looked, smelled, and felt clean and cold already, but I sure wouldn't have risked drinking it unfiltered (as we saw several other groups doing- just say no to unfiltered water folks, seriously, not worth it). Okay, the actual review stuff: I'm ashamed to admit I'd never actually used a filter before, though I've seen other people do so. I'm also *not* kinesthetically intelligent. But the Sawyer mini is super easy to understand and use, lightweight, and doesn't have a lot of tiny parts or really much you can do to screw up. I did a test run when it was delivered, found it easy and obvious, and left the flushing syringe in the cabin because we were on a day hike. On the trail it was 100% slick. The included 16 oz bag for untreated water is a little small, and can be challenging to fill in still water, but performed well despite those limitations. As mentioned, the water was already very clear- no visible particulates, and I was able to filter about 1.5 liters in around 8 minutes, including the water-gathering. I assume that dirtier water with more particulates would filter slower- for the water I was filtering, the flow rate was just as fast as my tap water test run, and it was easy to speed up with some gentle pressure on the bag. I should note that I found an actual water bottle *much* easier to filter into than my hydration pack bladder with its floppy body and wide mouth (the last minute extra tossed-in bottled water was useful on two fronts!), so I'd highly recommend carrying a lightweight bottle for filtering into even if you intend to eventually drink it out of an in-line system. The filter, straw, and backflow syringe fit easily into a clean ipsy-type zip case and were light and easy to pack and carry. I will invest in some screw covers or other capping solution so as to avoid water leakage in the future after use, but this wasn't a big deal for me. I'll likely also toss in some alcohol wipes for future trips to ensure clean surfaces after the parts have been jumbled together. Overall, while I imagine that folks who actually are backwoodspeople have better, higher-volume/higher-flow filtering systems and solutions, I'm 100% satisfied with my little Sawyer mini and its totally accessible price point and feel confident it will perform when needed.

Mocht er ooit een probleem zijn met de waterlevering, dan is deze filter een perfecte uitkomst. Gekocht op basis van de vele lovende reviews, ook op YouTube, en blij dat die in mijn bezit is. Hoop het nooit nodig te hebben.

Ce filtre est vite devenu un must-have dans le domaine, supplantant largement les Katadyn et autres. LEGER (93 g pour la totalité, 60 g si l’on emporte que le filtre et la gourde) : Filtre : 38 g Gourde souple 0,47 litre : 22 g Seringue 50 ml : 31 g Paille : 2 g Pour les courts séjours on peut tout à fait se contenter d’emporter le filtre et la gourde seuls, pour 60 g. Lors de plus longs voyages on peut coller un bouchon percé au diamètre de l’embout de sortie du filtre juste autour de cet embout, cela permet de visser n’importe quelle bouteille d’eau ou de soda achetée partout sur la planète. Cette astuce donne aussi la possibilité de remplacer la seringue (pas forcément au top pour son usage) par une bouteille plus volumineuse et donc plus puissante. PEU ENCOMBRANT : Filtre : Longueur : 13,5 cm ; Diamètre : 3,5 cm Gourde souple : 25 x 12,5 cm Seringue : Longueur : 15 cm ; Diamètre : 4,5 cm Paille : Longueur : 16 cm ; Diamètre : 0,9 cm EFFICACE : Le plus fin du marché avec ses 0,1 microns, il filtre la plupart des organismes naturels à l’exception de certains virus. Bactéries (salmonelle, choléra, e-coli), protozoaires (cryptospridium, giardia), tout y passe… ou plutôt ne passe plus. Mais, avant de crier victoire, il faut voir les limites décrites plus bas… DURABLE : Ce filtre est annoncé filtrer jusqu’à 100 000 gallons US soit environ 378 500 litre. Il semble évident que l’on n’arrivera jamais à filtrer cette quantité puisqu’à raison de 10 litre par jour, cela nous prendrait plus de 100 ans. Dans les faits il vaut mieux changer ce filtre 3 ou 4 ans après sa première utilisation. Outre les pores de la céramique se bouchant petit à petit jusqu’à l’obstruer complètement, le développement des bactéries à l’intérieur du filtre n’est pas exempt, à la longue, de le transformer en machine à intoxiquer plus qu’à assainir. UTILISATION : Rien de plus simple. Remplissez la gourde souple d’eau impropre à la consommation, vissez-la au filtre du côté de l’entrée (une flèche indique le sens de traitement de l’eau, de l’entrée vers la sortie), surélevez la gourde au-dessus de votre tête en prenant l’embout de sortie du filtre dans votre bouche et laissez la pesanteur faire son action. Au besoin, et pour aller plus vite, vous pouvez aussi légèrement presser la gourde (mais n’abusez pas sous peine de voir celle-ci exploser). Si vous voulez remplir une bouteille d’eau traitée, placez l’embout de sortie au-dessus de la bouteille, suspendez la gourde en hauteur pour éviter d’avoir à la tenir trop longtemps, et laisser à nouveau faire la pesanteur. NETTOYAGE : C’est là le rôle de la seringue. Après chaque traitement, et surtout si l’eau était vraiment sale, il est important de nettoyer le filtre. Pour se faire, il suffit de remplir la seringue d’eau pure ou traitée et d’injecter dans le filtre cette eau claire à l’inverse du sens de traitement. Le jet ainsi créé va repousser les impuretés bloquées dans le filtre vers l’entrée de celui-ci et, ce qui est encore mieux, les éjecter. Dans les cas les plus extrêmes il sera nécessaire de réitérer cette action jusqu’à ce que l’eau coule le plus clair possible. PRECAUTIONS D’EMPLOI : Attention, ce filtre (comme tous les filtres en céramique) supporte très mal les températures inférieures à 0°C. Il reste toujours un peu d’eau coincé dans le filtre, aussi cette eau résiduelle peut geler et briser la céramique. Autant dire que le filtre sera totalement inopérant après cela. Lors de vos randonnées hivernales il est donc fortement conseillé de ranger le filtre au plus près de la chaleur corporelle, y compris la nuit où il pourra carrément dormir à l’intérieur du sac de couchage. LIMITES D’UTILISATION : Elles ne sont pas négligeables puisque les pollutions humaines au rang des pesticides, fongicides et autres “suicides“, ne sont pas filtrés. Les métaux lourds échappent peut-être aussi à ce filtre (mais c’est à vérifier). Ainsi, sur le terrain, on évitera le plus possible de puiser son eau dans les cours d’eau les plus importants (contenant généralement, et concentrant le fruit de ces déchets humains). Exit donc l’eau des fleuves, surtout dans les régions les plus “civilisées“ ou hautement développées. On laissera de côté aussi, et autant que possible, les eaux trop boueuses. Cette boue peut très vite s’accumuler dans le filtre et le boucher rapidement. Si on n’a pas le choix, il est nécessaire dans ces conditions de laisser l’eau bouseuse se décanter (le limon boueux se dépose lentement au fond du récipient, pour peu qu’on lui en laisse le temps).
