first need water purification manualThis can help extend the life of the cartridge when used with dirty or turbid water sources Excessive force may break the canister internally. Crystal Clear Water - providing the world's best water purifiers. This unit produces appealing water with no off taste very efficiently. Other filters that were in use on the trips I've been on have clogged, broken, or produced less appealing water all with a far greater level of effort. One must either carry a spare or try to guestimate the remaining life before hitting the trail. Even with that drawback I would rely on the First Need purifier over every other handheld device I've tried. A real quality pump. If you are a lightweight packer, this isn't for you. You probably won't find a lighter pump of this quality, but when you are pushing for the lightest weight possible, nothing you have will be perfect. Weight is important so I spend a lot of money trading older gear for newer lighter gear. I'm so confident in the First Need that it is the only thing in my pack that is not an opportunity for improvement. My First Need purifier is the first thing that goes in my pack. I bought an extra filter a couple years ago thinking that sooner or later the original would need replacement, it hasn't had an issue yet. Back flush per the instructions after every use and it will serve you for years. They were suffering through purifier tablets. The water always tastes good to me. I always prefilter with an old T-shirt before running through the filter and that really increases filter life. The water tastes perfectly clean, and it is very easy to operate. The pre-filter helps greatly. It comes with blue dye for testing the integrity before you head out on the trail. It's very reassuring to know that this purifier is so stringent. I love the 1st Need, and also love the piece of mind that comes with a quality product. Thanks 1st Need!!! The filter provided water on the push and pull stroke so it yields water quickly.http://bobiniauto.com/userfiles/extron-sw2-usb-manual.xml

The water tastes good (no unusual taste) and is crystal clear. Good instructions tell you how to test your filter for proper function before you go on your trip so you won't be stranded in the field with a non-functioning filter (like I was with the Hiker Pro I had before I got my First Need filter). I have used it while hiking the Inca Trail in the Peruvian Andes, filtering water from springs and fountains on the trail and never had a problem. (Everyone else was spending money buying bottled watter.) It worked really well and pumping is quite easy. I highly recommend this filter as it seems to be (the only one?) on the market that gives pretty complete protection. I recommend getting a Nalgene bottle or some other container that mates with the filter - makes filtering much easier. In the owners manual you are instructed to run a glass of water with food coloring through the element to test its integrity before each trip. Do this and you can actually remove the coloring from the water!. Well. I was amazed. Anyhow, as a testament to its performance, I met a guy on the trail using a MSR purifier and while gathering water I was able to fill two bottles in the time it took him to fill one and he was sweating by the end of it all! The water tastes perfectly clean, and it is very easy to operate. The pre-filter helps greatly. It comes with blue dye for testing the integrity before you head out on the trail. It's very reassuring to know that this purifier is so stringent. I love the 1st Need, and also love the piece of mind that comes with a quality product. Thanks 1st Need!!! I've had it for five years with no problems. I've tried all the MSR ones and a few others only to come back to this filter. It filters faster than all the others, and doesn't clog as easy because it has a great pre-filter. The replacement filters are expensive, and I get about one season out of them. I'm out at least 15 days of each month for most of the year. Damn life's tough!!http://www.helpenergy.cz/userfiles/extron-sw2-hdmi-manual.xml Great purifier, buy it and forget about it! dudes! I purchased my unit well over 20 years ago. Used it on hikes in the Coast and Cascades ranges of Oregon and Washington. And really put it to the test while while trekking in Myanmar, Central America, and travels from Ghana to Namibia. Never had an issue, never suffered from water borne problems. Definitely a lifesaver and definitely a product to recommend. Thanks for the review. Do you have any pics you could share. Also, I'm wondering how much this weighs? 5 years ago That means you don’t have to use the chemicals other require or the addition of iodine to make water safe to consume. I believe the newer version XL filters are backwards compatible as I’ve not had any issues with using them on my version. This saves the need for extra hands to keep stuff steady. The double-pump action-which filters in both up and down stroke, saves you a lot of extra effort. However, depending on your water sources, results may vary. I follow the backwash cleaning procedure described in the manual after most trips. Would recommend and buy again if I lost this one. Thanks for sharing a helpful purifier review. 5 years ago Baldy, Yosemite, Shasta, Yreka, and also overseas. Greece, Mexico. never had to regret it. I will be glad to have it in any kind of local problem. I keep it and blankets in my trunk. The old cartridge model was called a First Need Deluxe (left) and the new one is called the First Need XL (right, in photo.) As far as I can tell, the Deluxe cartridge has been pulled from distribution. They’re impossible to find and if you do order one, the new XL model arrives instead. But the bad news is that you will need to buy a new adapter if you use a platypus water bladder. The flow rate has increased slightly from 1.8 liters per minute to 1.9 and the cartridge’s lifetime has increased from 135 gallons to 150 gallons.http://www.statcardsports.com/node/12293The First Need is the only chemical-free portable water purifier that is certified to meet federal EPA microbiological purification standards against cysts, bacteria, protozoa and viruses. In addition it removes harmful chemicals such as herbicides, pesticides, diesel fuel, and chlorine which you will find aplenty if you hike through agricultural and semi-industrial areas. Two words sum it up: “instant water.” I’ve tried gravity filter systems, chlorine dioxide tables, and other pump systems and I keep coming back time and again to the First Need. Viruses are still less of a problem in the US, so you should be ok. Most other filters don't, which I find troubling. I attribute this to the lack of a pre-filter on the intake hose, which would filter out silt and other large particulates. Surprising that they don't add this. It's rather obvious. It doesn't sound like you can use a small mouth recycled bottle or platypus with this filter via a direct connect. Carrying a nalgene bottle must be awkward if you want to go lightweight.Does the handle detach? I read your twitter profile. Also, I actually switched to a wide-mouth nalgene because of the compatibility issue. I also notice a map of Scotland. Planning going well then? Yes, I have a Challenge route planned out, just need to work out a few more details before I seek feedback from the chorus. The First Need is a great filter, but the ergonomics just don't compare to the MSR. The lever style pump handle on the MSR is much less fatiguing than the FN's plunger, and the way the Nalgene solidly screws onto the MSR makes the whole process of filtering water much easier. Usually when filtering water, I'm perched on some rock jutting out into a lake and the fewer things I have to hold, the better. I just cast the intake line into the lake and start pumping. I also like to disassemble it and dry it out between trips. What's growing in that water trapped in your First Need as it ferments in your gear closet? Between trips I take the clean water cap off the First Need filter to let it dry out. I seem to recall that they recommend pushing a diluted bleach solution through if its a major concern. I guess I use mine so frequently that it's never been an issue. Same reason I don't bother drying my hydration bladders. No point. Then got into the PCT and lightweight backpacking, and switched to Aqua Mira. Problem with that is that there never is instant water. 30 min minimum and 4 hours best. Now I use the ULA gravity filter, which uses the Hiker Pro filter element, and carry Aqua Mira as backup, and when I need massive amounts of water, such as when a dry camp is coming up. Had one for years and it's never let me down. It is just a bit bulky compared to some of the newer designs. But you can't argue with this one fact: It just works. I'll be looking for it. FirstNeed is worth the trouble. There's a youtube.com video that shows what came out after a backwash, that sold me really quick. I'll deal with the extra weight. You have to see this, to believe this. Weighing 4 oz, if it works well, I may switch. I'm not mentally ready for the switch to gravity based or inline systems. Your information and endorsement of the First Need really helped me finally decide on it. I had been using a Sweetwater walkabout for years, but it was discontinued years ago and despite it's light weight and small size I had to also use drops in a 2 step purification process, which was a pain. The plunger handle broke on my last trip and although I repaired it, I'm afraid I don't trust it to hold up in the backcountry. Thanks for the great info on your site. It is the ONLY purifier sold by REI and there's a reason for that. Plus, I'm glad to have you as a regular visitor to the blog. Bring us back some pictures from your hike! I have been researching purifiers and filters for 3 months. Comparing all the information available.It is certainly not the best looking.I beat the filter clog with an MSR SiltStopper spliced into feed line just after the factory input screen end. The Silt Stopper filter is inexpensive and keeps the pump effort like new. When storing it, I first throw away the MSR filter. I then make a quart of chlorine dioxide water solution (throw a tablet in a bottle and clean both at he same time), rinse the MSR filter holder, the factory tip and then pump the rest of the solution through it before putting it away. It has pumped a lot of water for backcountry wounds and burns in places with otherwise limited potable water sources. Sometimes from ash filled waste water. It’s a little heavier than some, but an amazing filter nonetheless. It is so fast and easy to pump. I like the plunger because I’m usually sitting or kneeling on a rock and pushing down is just a natural movement. It started squirting a bit at the plunger so for a trip a couple weeks ago i thought I’d try an MSR Miniworks EX. That is without a doubt the most disappointing piece of equipment I’ve ever purchased. It’s been returned to REI and we bought a new First Need. It would still pump the third liter but the flow slowed so dramatically it drove me crazy. The first night out I thought I would time the fifth liter- 15 minutes! 15 minutes to pump one liter. Every two liters take it apart, scrub the element with the little enclosed scrub pad and hope you don’t drop something or drip unfiltered water onto the clean outlet end of the element. It was awful. You can tell when it’s really slowing down because it makes an airy squishing noise. When you take it apart to clean, the back pressure in the chamber is surprising. I was really surprised because I love MSR products and bought this on reputation. I kind of thought that meant after a trip or maybe at least every couple gallons. I didn’t think it meant after every two liters. Don’t walk away from the MSR filter—RUN! Using it side by side, with MSR, and platypus, pound for pound, it’s the best. Bass aluminum boat we were forced to take shelter on one of the lakes Islands.This past trip I screwed on the last filter that I have and need now to order some replacements. Thanks for the info. I was worried about compatibility. I agree this is the best piece of camping equipment you can have, the next is probably a good fire steel. These are 2 absolutely essentials for wilderness campers items. Can you buy a replacement pump only? Thanks. I mainly use a sawyer these days, but have held onto my First Need.

Barnacle Bill The Sailor 5.0 out of 5 stars The other, a LifeSaver bottle is 50 more expensive initially but the filter lasts for 1,000 gallons vs the 180 gallons of the Xle filter. On the other hand, the LifeSaver filters are more expensive and have a shelf life of 2 years after you open them. The Xle filters have an unlimited shelf life. The LifeSaver bottle only holds 0.75 liters. To fill a 3 liter bladder you'd have to fill and empty the bottle 4 times. With the Xle filter, you can pump endlessly into a bladder or other container. This is a big benefit especially if you're hiking in a group. The LifeSaver bottle also requires enough water depth that you can fill the bottle by submerging it. The Xle filter only requires a couple of inches of water to submerge its pre-filter. And that pre-filter keeps larger contaminants from prematurely clogging the filter. That, plus a clean out port means the Xle can better deal with poor quality water. Both filters can produce clean water at a rate of about 2.0 liters per minute which is very good in my opinion. Either solution is viable and the life cycle costs aren't all that different in the long run. I choose the Xle because it seemed to offer more real world convenience and functionality than a LifeSaver bottle especially if you're hiking with more than just yourself.Decided I needed another set up for friends to use so I bought this one for me and will loan my old one out to friends and family. The ability to purify and remove viruses makes this filter a have to have item in my pack. Also recommended by Hill People Gear as the only filter worth carrying in their backpacks. I have run hundreds of gallons of water through the filter over the last twenty years and had to change the filter pack once or twice and then only as a precautionary measure. Never had a failure to filter or clog in the field keeping in mind I try to find somewhat clear water and if the water is too mucky with silt or debris I pre filter by wrapping a coffee filter around the intake filter on the hose, this keeps really small silt from entering and clogging my filter main element.I have tried multiple water filters and purifiers while hiking and I keep coming back to the First Need XLE. It pumps water fast and is by far the best tasting water I have ever had. It also gives me peace of mind that it purifies the water removing pretty much everything. The only negative is that it is bulky and heavy. Definitely not 16oz. Mine tips the scales at around 22 oz dry. I would love it if they could make a model half the size and weight. I wouldn't even mind if the filters didn't last as long. 180 gallons is enough water to have a gallon a day for six months. Overall a great purifier that should be more popular than it is.As best I can see, this First Need filter was and still is clearly the best portable filter available, being the only one that is certified to filter out all pathogens including viruses. When I bought my first one of these First Need filters, it was the pre-eminent portable water filter, widely regarded and recommended as definitely the filter to get. REI and all the best stores featured it. But since then it has become almost invisible in the marketplace, Amazon being now just about the only place that sells it - and Amazon won’t even show it to you on a search for portable water filters, despite the fact that it has about the highest customer review ratings, you have to search for the exact brand name for Amazon to show it. I’m not quite sure what that is all about, but it’s apparent that General Ecology is much better at making filters than at marketing them. As I mentioned briefly above, but bears repeating, this First Need portable filter is the only one certified to filter out all pathogens including viruses. So in my mind that makes the First Need still plainly the best available: what else matters in rating filters if they don’t really filter. One of the super-attractive consequences of this First Need being the best-filtering filter is that it is easily possible, and recommended, to regularly test and verify that its filtering function is intact and working, simply by filtering some clean water with a few drops of food-color dye added: if the filter removes the dye, then the filter is still working, not broken or cracked or torn or pierced. As best I can tell, no other filter has any such easy integrity verification ability, which counts for a lot in my mind. And my First Needs have both worked perfectly, the first one for decades. Boy, I got that wrong. That’s a bit disappointing, that General Ecology hasn’t done a better job of keeping its price down. And there are certainly lots of opinions around that the First Need is over-priced. Also the First Need is a few ounces heavier than a lot of the competition. And a bit clunky. But what do any of those things matter, if the alternatives are filters that don’t really filter. If you’re really determined not to shoulder the extra dollars or the extra weight, you could always just use paper coffee filters to filter your water; it’s just that they, like all the other competitors, won’t really filter your water. Anyway, I’d really like to see some better, more serious competition for the General Ecology First Need. But until then, this is the only portable water filter that really filters, I don’t see how I can give it anything but 5 stars.I have 2 First Need Purifiers. One is mine I bought in 1997, The other is for my son I just bought. Both were used on our last Backpacking trip. Other than new cartridges, parts are hard to find if something breaks and the purifier is a little on the heavy side compared to other purifiers. However: I had Giardia once (before a 1st need) and I would never use any purifier except First Need now. Only puifier that is EPA rated. I would like to see the company slim down the pump components and decrease the canister somewhat. This would save several ounces (and cost) and make it more competitive with other purifiers.The first day I drank the water cold was OK for some reason on the third day the water tasted off and I got a belly ache and on the second visit to the toilet in half an hour, the stool was a bit free flowing, I had food on top of the belly ache and was OK after that.This is my filter of choice. My wife and I took this filter to many places with questionable water sources. In Mexico, Guatemala, Jordan, the Jungle of Ecuador and many other places this filter provided us with clean drinking water. We never had as much as a stomach growl. It is the first item I put in our backpack every time we go somewhere, even in North America or parts of Europe. This is one of the few filters that can filter out viruses. Sturdy, reliable product, very efficient. Only disadvantage is that there is no indication that the cartridge is no longer effective. The unit comes with a dye, though, which shows if the filter action is still effective. We have pumped hundreds if liters through the unit's first cartridge. If in doubt, replace the cartridge. This filter is worth every cent.I see the other reviewer says that it. I see the other reviewer says that it would be too heavy for backpacking, and while his weight estimate isn't off, I still feel that it wouldn't be that heavy to carry around. That being said, really depends on what you're doing, right. If I'm going out for more then 48 hours, this things in my bag. It's not as large as you would imagine either, not that it's incredibly smaller though, but it's a good sized fit for my 80L pack. No constructive criticism, it works as it should and has a great space value and imo weight value.Will filter anything. With dirtier water or higher floating contents, the pump filter will last for a shorter period of time but generally speaking each filter is good for at least 7 days with four to six people using it all day everyday (on a back country canoe trip).It produces extremely good quality water.

Robust Durability — Increased XLE ELITE canister strength allows 2 to 3 times greater resistance to damage from dropping and other physical shocks.Prices are indicative only and may vary by country, with changes to the cost of raw materials and exchange rates. Wilderness medicine professionals recommend treating water for viruses as well as bacteria and cysts.Does it include common parts? There are a bunch of bad reviews about it from 1999-2000 but much less now that it has been redesigned. There are also complaints about how difficult it is to pump and poor customer support.But, they have a PDF document on this page that describes results of testing and the First Need did a great job.Carbon eliminates odor and off tastes too. Easy to carry and simple to use, just take off the lid, dip it in the water, put on the lid, suck or squeeze out the water. It then employs an ion-release technology to greatly reduce residual iodine, and coconut-carbon scrubbers to further minimize any residue. The ViruStat cartridge is preceded by a replaceable 1-micron filter that removes at least 99.9 of pathogenic cysts. A prefilter is installed ahead of the cyst filter to remove sediment and organic contaminants extending the life of the cyst filter. The ViruStat cartridge, cyst filter, and prefilters are all replaceable.It's not efficient to open and close the lid over and over to get a pot of water.You just add water, shake it, and press a button.Since the MIOX Purifier just needs camera batteries and salt to operate, it’s maintenance-free, delivering more water, more easily than any purifier ever before. Well, that's what the literature says anyway.Then, take your MIOX and put a bit of salt in one spot, then pour a bit of water in another spot, then shake it to mix them together. Then by pushing the button, you are delivering an electric charge that changes the mixture to a mixed oxidant solution. The more water you want to purify, the more times you have to mix the salt and water and push the button. A bunch of lights tell you if the mixture is too weak, too strong, or just right. When the solution is ready, you pour it into your raw water and then shake that container up. You can use a test strip to check that the water is correctly treated. After 15 minutes, all the viruses and giardia are dead. After 30 minutes, almost all of the cryptosporidium are dead, but you need to wait 4 hours to make sure they are all goners.Personally, I see this as a terrific way to purify water before filtering it. The MIOX is just 3.5 oz. so I'd treat a gallon of water, wait 15 minutes, then pump it through my filter to remove all the dead stuff, tastes, and odors. Most filters would also remove any undead cryptosporidium too.It can use 4 lithium, NiMH, NiCad, or alkaline batteries, weighs 8 oz.The lamp is good for about 5000 uses.
