The Mini is Sawyer’s smallest, lightest and most versatile filter. This 0.1-micron absolute filter weighs a mere 2 ounces, is rated up to 100,000 gallons and can be used the following ways:
(drink directly as shown above)
The MINI can be attached to the included collapsible drinking pouch, inline on a hydration pack, on a standard soda bottle, or simply use the included drinking straw to drink directly from the water source. How is that for versatility?
Can I filter salt water? – No, but that would be nice!
Can the filter freeze? – Brand new filters can be frozen. Once used avoid freezing a filter as it is unknown if freezing will damage the fibers. Try to keep the filter in a plastic bag in a pocket or in your sleeping bag if you’re in below freezing temperatures.
Does it filter taste or chemicals? – The Sawyer filter removes taste that comes from bacteria, dirt, and green matter but not from chemicals or heavy metals. Sawyer filters are not made with charcoal. While other portable filters have charcoal, they lack in the amount of media and adequate dwell time to be truly effective. Therefore, they only remove small amounts of heavy metals, pesticides, etc. (when used in real life applications). Try using better sources of water if possible.

THE 0.1 MICRON ABSOLUTE DIFFERENCE
- Sawyer’s fiber walls are thicker and more robust than other Hollow Fiber Membranes. This allows for higher pressure both for filtering and for backwashing. Sawyer filters can handle 60 PSI forward and 20 PSI backward.
- Sawyer has a proprietary process of making all pores more uniform in size.
- Sawyer’s proprietary process allows for more pores giving better flow and less cleaning.
- Sawyer’s proprietary design has a self-priming mechanism to eliminate air locks making them much easier to restart.
- Sawyer 100% tests all filters to insure no pore is larger than 0.1 microns.
- Sawyer 100% flow tests all filters to ensure adequate flow.
- Sawyer 100% tests all filters after final assembly to ensure quality.
- There is nothing to wear out inside the filter. If water is owing, it’s good.
THE 0.02 MICRON ABSOLUTE DIFFERENCE
- The 0.02-micron purifier has all the advantages of the 0.1-micron filter but with 0.02-micron pores.
- It is the only filter that removes viruses so effortlessly. Gravity does all the work.
- There are no harmful chemicals or heavy metals in the filter.
WHAT ARE THEY
Coliforms are a broad class of bacteria found in the environment.
It’s chocolate ice cream, but you get the point
WHERE DO THEY COME FROM
Both the harmful and non-harmful bacteria primarily come from the feces of humans and other warm-blooded animals. They can also come from rotting vegetation. The presence of non-harmful coliform bacteria in drinking water may indicate a possible presence of harmful, disease-causing organisms.
HARMFUL VS. NON-HARMFUL
Most Coliform bacteria do not cause disease. Coliforms are broken into 3 groups:
Total Coliforms They include bacteria that are found in the soil, in water that has been in influenced by surface water, and in human or animal waste.
Fecal Coliforms both harmful and non-harmful: They are the group of the total coliforms that are considered to be present specifically in the gut and feces of warm-blooded animals
- Coli – a subgroup of the Fecal Coliforms: Some strains of E. Coli can cause serious illness.
PROLIFIC VS. NON-PROLIFIC
E.Coli is generally not found growing and reproducing in the environment. Total Coliforms (of the non-harmful type) are very prolific and once introduced to a surface can spread quickly. These non-harmful types include both fecal and non-fecal Coliforms.
COLIFORMS AND CLEANLINESS
The spread of Coliforms can be combated through good Hygiene. Simple washing with soap and water will prevent the spread of them.
SPREAD OF COLIFORMS
Coliforms can spread by touching the clean end of the filter with a dirty hand, by animal contact, or even by dust particles. Proper hygiene techniques must be taught with the use of the filters. Otherwise, contamination of the discharge side occurs. This is supported both by the Tuft’s study and the Messiah/John Hopkins study referenced later in this handout.
TESTING FOR COLIFORMS
Because Total Coliforms reproduce very quickly they are easy to test for. A high indication of total Coliforms is usually a good and inexpensive way to determine if water needs treatment but it does not guarantee the presence of E. Coli. This type of testing is broad and encompasses most of the non-harmful types of Coliforms.
COMMON MISTAKES MADE WITH TESTING
Because the Total Coliform testing is inexpensive most people believe it is a simple way to see if the filter is working. What they really end up testing is not that the filter is working, but whether or not the discharge end has been contaminated. It only takes a few Coliform bacteria on the discharge to contaminate the sample. Once contaminated the bacteria very quickly grow in the test solution giving a positive test result.
HOW TO PROPERLY TEST A FILTER
There is no quick and easy field test to see if a filter is working. Even an E. Coli test can yield false positive results if the discharge end of the filter is not clean. Simply running water through the filter and doing a total Coliform test does not prove if the filter is working or not. Unless the filters discharged has been cleaned of ALL bacteria, you are going to get a false positive result. People believe that because they processed their sample correctly, they tested the filter correctly. They do not take into account the contamination that could have occurred on the discharge side of the filter and wrongly assume the filter is not functioning. Every time we hear of filter failure it always turns out to be procedural errors. Backwashing and pushing will remove the harmful bacteria, but will not remove all the bacteria. The small amount of non-harmful bacteria that remain will multiply very quickly and yield a false positive test result.
Sawyer has working filters that have been in continuous use for over six years and had filters which have filtered hundreds of thousands of gallons of water. Sawyer’s fibers are so robust, they can be back washed and reused perpetually.
- When backwashing, even the stubborn dirt can be forced off the fibers.
- Sawyer’s robust fibers will not “wear out” over time.
- Sawyer fibers will not break or become damaged if dropped. Only breaking the sealed casing and “playing” with fibers or freezing the cartridge after it is wet could damage the fibers.
Are you sure your water is safe to drink?
Even water that is crystal clear from a fresh mountain spring can be loaded with bacteria and protozoa that cause illness.
Sawyer’s 0.1-micron absolute filters house a cluster of micro-fibrous tubes which use similar technology found in medical dialysis. As water passes through the side walls of the tubes, harmful bacteria and protozoa are trapped on the outer walls so you can be confident your water is safe to drink.
THE SAWYER ADVANTAGE
1. Absolute Microns – Sawyer tests to verify that no pores in our letters are bigger than the listed pore size, unlike other filters that list a nominal or average pore size. This is why we o er the highest level of filtration.
2. Longer lasting – Sawyer filters are robust and can be cleaned over and over. No replacement cartridges needed.
3. No air locking – Sawyer filters will self-correct and not air lock.
*Though the strand size is 0.05 micron in size, this bacteria is shaped like a corkscrew, therefore the shape of the bacteria prohibits it from passing through our 0.1-micron pores.
**Viruses are not commonly transmitted in water, however, Sawyer’s 0.02-micron purifier will filter 99.9999% of viruses. If you’re traveling to an area where there is a known hepatitis or polio outbreak consider using a purifier instead of a filter.
The Sawyer MINI Water Filter is rated to 0.1 microns absolute, weighs only 2 ounces, and filters up to 100,000 gallons! This award-winning system is reliable and easy to use.
The MINI can be attached to the included collapsible drinking pouch, inline on a hydration pack, on a standard soda bottle, or simply use the included drinking straw to drink directly from the water source. How is that for versatility? Like all Sawyer filters, a proper backwashing can restore up to 98.5% of the filter’s flow rate. That means no expensive cartridges to replace, ever.

1. Find area with a damp ground. Usually low lying areas can produce more water, since water flows downhill. (You can also dig a seep next to a lake, stream or pond by digging back from the edge.)
2. Neighboring your damp area, begin to dig a hole about 2 – 3 feet across and about a foot deep.
3. If there are rocks nearby, line your hole with them. This will help in preventing any type of sediments to be mixed in with the water. (For example, when you scoop the water) Always line the bottom as well as the sides, while trying to position the stones as close as possible. (like a puzzle)
4. Let water begin to fill hole.
5. Scoop out the dirty, muddy water in order to remove as much sediment as possible. Allow any remaining sediment to settle out completely until the water is clear. Repeat this process several times, stirring up the sediment before beginning to scoop. (This process can take several hours or can be done over several days.)
NOTE: Filter the water through a cloth to remove sediment. If you have the means, boil it before drinking.
