1 CLEAN WATER THE FASTEST EASIEST AND MOST COST EFFICIENT WAY KIDNEY DIALYSIS TECHNOLOGY ADAPTED TO WATER FILTRATION IF YOU CAN CLEAN BLOOD, YOU CAN CLEAN WATER

2 FAST These are point of use filters. Water is on demand so there is no need to store water and increase risk of post-contamination For higher volumes of water increase the head pressure or attach multiple filters to a container The robust fibers can handle up to 40 psi Up to 2,575 gallons (9733 Liters) per day EASY No chemicals, electricity or technical training required Simple enough that anyone in the world can understand how to use and maintain it Installing a filter on a standard five gallon bucket takes literally minutes Maintenance is even easier. Simply backwash the filter when it stops flowing, a process that takes 30 seconds No moving parts to break down Up to 342 gallons (1,292 Liters) per day COST EFFICIENT The most cost efficient solution where surface water is available One filter at no more than $50 can yield millions of gallons of water cleaner than US bottled water This is a one-time cost. No replacement cartridges necessary With each kit weighing less than a half a pound, these filters are easy to transport in mass quantities (find the bucket when you get in country) Up to 3,894 gallons (14,719 liters) per day

3 A CLOSER LOOK: THE TECHNOLOGY What it does... Up to 500 gallons per day with each filter using nothing more than a common 5 gallon bucket. Higher yields are possible with increased head pressure or other configurations. Millions of gallons for a low onetime cost Simple design and fast construction Easy maintenance and use Providing clean water in over 70 countries How it Works Sawyer water filters use Hollow Fiber Membranes, a technology developed for kidney dialysis. Our filters are comprised of tiny "U" shaped micro tubes that allow water to enter into their cores through tiny micro pores. The pointone Filter s pores are so small (0.1 micron absolute) that no bacteria which cause Cholera, Typhoid and E. Coli, protozoa, or cysts can get through. The filter attains the highest level of filtration available today at 7 log ( %), while maintaining a very high flow rate due to the large amount of tubes. If viruses are an issue we offer the PointZERO TWO Purifier (0.02 micron absolute pores). This is the first (and thus far only) portable purification device to remove viruses mechanically. It does so at a >5.5 log ( %) rate, exceeding EPA and NSF recommendations. Each filter is certified for ABSOLUTE microns. That means there will be no pore size larger than 0.1 microns in the biological filter and 0.02 microns in the viral purifier.

4 A FEW OF THE KEY FEATURES Highest filtration rates available At 0.1 micron absolute, it is impossible for any bacteria, protozoa or cysts to pass through the filter and at 0.02 micron absolute, it is impossible for viruses in addition to bacteria, protozoa and cysts to pass through the purifier. These are true barrier filters. Simple design and construction No more digging wells if there is a water source, no constructing sand filters, and no more purification chemicals. Families are able to construct and adapt their filter to locally found containers in literally minutes. The kit includes everything you need to attach the filter to any plastic bucket or container. (Bucket not included) 1. Obtain a clean plastic bucket or container. 2. Use the hole cutter to drill a hole 1.5 inches from the bottom of the bucket. (This can be done by hand) 3. Screw the connector, hose, and filter onto the bucket. 4. Fill the bucket with water from any source, lower the filter head below the water line, and let gravity do the rest. The kit comes with these items*: Backwash syringe Hose, filter and connector Hole cutter *items not pictured include a filter hanger and detailed picture instructions with room for translation. Extremely cost efficient One system could provide clean water for a family, school or small village for pennies a day. Fast flow This is a POINT OF USE SYSTEM. The high flow rate eliminates the need to store water, which reduces the chances of water being contaminated after it is filtered. The only external force required for the system to function is GRAVITY. The 0.1 micron filter has a flow rate of about 1 liter per minute and therefore is capable of filtering over 1000 liters per day. The 0.02 micron purifier flows at an approximate flow rate of 0.5 liter per minute, yielding over 500 liters per day. Easy maintenance Maintenance of this filter is very simple. When the flow rate slows or the filter clogs, simply backwash it with clean water using the backwash syringe provided in the kit. The ease of operating this system makes it self sustainable and dependable. Natural disasters This system is a cost efficient and fast solution for clean water in the event of a natural disaster. Multiple applications These filters and purifiers make water so clean and accessible that people will not only use the filtered/purified water for drinking, but also for cleaning, bathing, cooking, watering plants and more.

5 MULTIPLE APPLICATIONS Micro Business Not only are these filter being distributed for humanitarian aid, they are also creating sustainable economic opportunities in several countries around the globe. According to the WHO, Water management is a key factor in the global battle to remove the scourge of extreme poverty and to build secure and prosperous lives for hundreds of millions of people in the developing world. Sawyer is collaborating with Partners Worldwide, an organization whose mission is to equip and connect business and professional people in global partnerships that grow enterprises and create sustainable jobs, to establish distributors and assembly facilities in several countries. So far, small businesses have been set up in Liberia, Kenya, Haiti, Egypt, and more to come. To learn more about Sawyer s Build a Business program visit Disaster Response Clean water is of critical importance after a natural disaster because existing water sources can very easily become contaminated and an epidemic of waterborne diseases can be just as deadly as the natural disaster itself. Sawyer filters offer a fast, efficient and sustainable solution to clean water in the event of a natural disaster. No electricity, chemicals or technical training is required. Not only will these filters provide immediate relief after the disaster, the filters will still be functioning years and years down the road. Hundreds of thousands of people are currently getting their clean water from Sawyer filters in Haiti. In fact, Sawyer has an assembly facility in Port au Prince and is using local labor to assemble and distribute filters to relief organizations. Tent city in Haiti.

6 FAQs How long does the filter/purifier last? Proper backwashing restores the filter to 99% of its original capacity. Since the filters and purifiers can continuously be backwashed and reused they have an extremely long life. The filter/purifier membrane may never need to be replaced, however when the flow rate slows or the filter clogs, simply backwash the unit with the provided backwashing device to clear out the pores. How often do you have to clean or backwash the filter? The frequency of cleaning depends on how dirty the water is. With relatively clear water, backwashing may only be necessary every 1,000 gallons. With extremely turbid or muddy water, backwashing may be required every 10 gallons. Nevertheless, backwashing is an extremely simple process and only takes a minute. Can you backwash with dirty water? We do not recommend backwashing with dirty water. If this happens, immediately run at least one quart of water through the filter and dispose before filtering water for consumption. Can you put muddy water in the bucket? Yes, though backwashing will be required more frequently. It will not alter the effectiveness of the filter to remove harmful pathogens. How much water can be filtered/purified per day? The flow rates of the filters and purifiers are determined by a combination of four variables: Head pressure (The distance from the top of the water to the filter) Altitude (The higher the altitude, the slower the flow rate) How clean the filter is The filter itself (there are slight variations between filters) The PointONE Filter with a 1 foot hose (Model SP180) attached to a standard five gallon bucket at sea level is capable of filtering up to 295 gallons (1117 liters) of water per day. The PointZERO TWO Purifier with a 3 foot hose (Model SP190) attached to a standard 5 gallon bucket at sea level is capable of purifying up to 87 gallons (327 liters) of water per day. If you increase the head pressure by either lengthening the hose, attaching the filter to a larger container like a 55 gallon drum, or constantly keep the bucket full so the top of the water is as high as possible, this will increase the flow rate. For flow rate charts visit Do you recommend pre filtering the water? Yes, and we have three recommendations for pre filtration. Option one, pour the dirty water through a t shirt or cloth before it goes into the filtration bucket. Option two, cut the hole in the side of the bucket at least 1.5 inches from the bottom of the bucket to allow sediment to settle and not go down the hose. Option three, allow the dirty water to settle before putting it in the filtration bucket. Do I have to use a plastic five gallon bucket? You can attach the filter to any size container you can drill a hole in. We recommend attaching the filter to a clean container that is either food grade or was previously used to transport food items. Do not attach the filter to a bucket that was used to transport chemicals. The filter will also fit into most water crocks by removing the existing valve and replacing it with the fittings supplied with the filter. See pictures on page 2 of brochure for examples. Will the filter/purifier remove salt, chemicals, pesticides or heavy metals like arsenic? No. Do you need a power drill to cut the hole in the bucket? No. You can cut the hole with the included hole cutter by hand. Are the filters and purifiers tested and approved? Our filters and purifiers have been tested by independent and qualified research laboratories according to EPA standards for water filters and purifiers. What do you mean by 0.1 and 0.02 micron absolute? Many other filters list nominal or average pore sizes which leaves the possibility that pathogens will be able to pass through some of the larger thanaverage pores. Absolute microns mean no hole is larger than 0.1 micron on the filter or 0.02 micron on the purifier. Further, every filter is tested twice to assure pore size and no leakage after assembly. These are true barrier filters so there is no questionable time period whether the water is safe to drink. Can I freeze the filter? We have not been able to conclude definitively whether freezing will harm the filter. Therefore, we urge you to take the precaution of replacing any filter you suspect to have been frozen, especially if it was exposed to a hard freeze.

7 A LOOK AT: FILTERS IN ACTION Give Clean Water, Inc. (GCW) is a 501(c)(3) non profit organization whose mission is to change the world by providing clean water to every person on earth who needs it and they are starting with the islands of Fiji. How they work: GCW works with local community organizations in Fiji to identify families in need of clean water. GCW then works with local volunteers to assist in gathering biographical and demographic information from each recipient family. Photos are taken and the GPS coordinates are recorded so teams of volunteers can locate the homes for installation. On installation day, team members made up of local volunteers and GCW representatives visit homes, install the filter and spend some time educating the family on how to maintain the filter. The teams also educate the family on basic hygiene and the importance of drinking and cooking exclusively with clean water. Two follow up visits are made to each recipient family within the first year after installation. In general, diarrhea, periodic typhoid outbreaks and stomach pains are common problems throughout Fiji. Prior to receiving the filters the families public water supply was contaminated with bacteria and protozoa because of inadequate treatment and filtration. Those families without access to plumbing get their water from a well, stream, borehole or rain collection device that is often more contaminated than the public water supply. Prior to receiving filters, the selected families were drinking the contaminated water and getting water borne illnesses. How it s going: Since 2008 GCW has installed over 1,300 filters in 19 villages and 7 schools in Fiji. An estimated 8,500 people now have access to clean water and proper hygiene and sanitation training. Follow up data on the recipient families indicate that all the filters placed two years ago are still functioning and there have been ZERO reports of water borne illnesses in villages using the filters even after cyclones and severe flooding. After the recent cyclone in December 2009, GCW s team went to local villages to access the effectiveness of the filters: Follow up data on the recipient families indicate that all the filters placed two years ago are still functioning and there have been ZERO reports of water borne illnesses in villages using the filters even after cyclones and severe flooding. "We have been using the rain water to drink and after filtration we get the pure water. The Department of Heath came to educate people to boil the drinking water but was very happy to find out the village had filters and said that we must use it and the proof is that no one in the village had dysentery. We are thankful to Give Clean water and will use the filters continuously. Also our laloma (love) to Darrel and the group Niko, Bavu Village December 21, 2009 GCW is currently working with the local government in Fiji to identify areas of greatest need, including where there are current Typhoid outbreaks. GCW will continue to distribute filters to the needy families in Fiji until every person in Fiji has clean water to drink. Learn more at
