Instructions for use


Effectively filter and purify water with the Sawyer Point ZeroTwo Gravity Purification System, which goes one step beyond Sawyer’s MINI and Point ONE filters to remove 99.997% of viruses in addition to 99.99999% of bacteria and 99.9999% of protozoa/cysts.


This powerful and convenient bag-to-bag gravity system with 0.02 micron absolute filtration doesn’t require any pumping. Just hang the system from any source off the ground, and gravity does all the work quickly — effortlessly purifying up to 4 liters of water in about 10 minutes.  NO REPLACEMENT FILTERS OR CARTRIDGES ARE NECESSARY.


How It Works

Gravity Does the Work - Take the gray reservoir and fill it up with water from any source — lake, stream, faucet, etc. After filling, hang the gray bag from a tree, the back of your pack, or simply hold it up with your hand. Connect the color-coordinated gray tube into the gray reservoir and clip the other tube end into the Point ZeroTwo filter.


Connect the blue tube into the blue reservoir, or directly into a water bottle, cooking pot, or other container. You’ll have 4 liters of fresh, clean, and virus-free water in about 10 minutes — ready to drink, to cook with, or fill water bottles.


0.02 Micron Absolute Filtration

Our water filters contain a high number of tiny ‘U’ shaped hollow fiber micro-tubes that trap contaminants while allowing decontaminated water to freely pass through at a high flow rate — eliminating the need to store water and reducing the possibility of water contamination after the filtration process.


Certified for 0.02 micron absolute filtration, the Point ZeroTwo Purifier has no pore size larger than 0.02 micron in size — enabling it to remove 99.997% of viruses (exceeding EPA and NSF recommendations). It also effectively removes harmful bacteria (like salmonella), protozoa, or cysts like E. coli, Giardia, Vibrio cholerae, and Salmonella typhi.


A Lifetime of Clean Water

The Point ZeroTwo Purifier’s filtering membranes are sturdy enough to withstand backwashing using the included syringe, restoring up to 98.5% of the filter’s flow rate.


The Point ZeroTwo system can be cleaned and reused almost indefinitely with no expensive cartridges to replace… ever. We recommend backwashing and sanitizing the filter after every outing for optimized use.


Fully field maintainable, the Gravity Purification System includes a faucet adapter for a more thorough backwash when you get back home.

Lifetime Warranty

If you have purchased any of the Sawyer water filtration products that came with their One Million Gallon Guarantee.  They will of course honor that commitment to you.


However recently that guarantee was challenged by one of their competitors by filing a complaint with the National Advertising Division of the U.S. Better Business Bureau. They challenged their ability to support that claim scientifically.  Unfortunately the data which Sawyer feels support the claim contains proprietary information that they were unwilling to share.  Therefore while these products are exactly the same, they will now come with a revised warranty; which is a Lifetime Warranty against any manufacturing defects. The filters contain a code such that Sawyer will know under which warranty you purchased the product.


Sawyer is proud to say that throughout the millions of filters which they have shipped in the U.S. retail market and throughout the world for disaster relief and for home use in developing nations very few have ever been returned for damage to the filter as a result of their handling or in distribution.  Each of Sawyers filters is tested 3 times to insure that they will work as claimed.  Not some random statistical testing but every single filter is tested three times at three different quality control points throughout its assembly process.


Sawyer Products Statements Concerning Their Filters

To help you enjoy your filter experience let us share with you the three most common issues which arise with these filters.

1)  “The filter is so clogged that it must be defective”.  We have yet to receive a filter or be unable to talk a customer through the process to clean and fully restore a clogged filter.  Consumers often confuse our filters with other brand hollow fiber membrane filters which cannot be cleaned as aggressively as our filters can.  If you follow the cleaning and storing instructions you will be able to fully enjoy the Sawyer filters for a lifetime.

 2)  “It leaks at the intake”.  The intake side of the screw on filters come with a washer to buffer a snug fit with the dirty water vessel.  Some people are prone to over tightening the connection (and you know who you are) and thus they unseat the washer either causing it to jam up into the filter or fall out.  With just a reasonable tightening of the filter to the vessel, this will not happen.  The washers are replaceable if you damage or loose one.

3)  “I froze the filter, is it still good”?  The simple answer is no.  There is no way to know if the fibers were damaged when frozen.  The test to find out is very expensive and far greater than the value of the filter.  Therefore, it is best to replace the filter.  The instructions clearly states that freezing the filter after wetting voids the warranty.  If a filter has never been used then freezing will not affect the fibers. But once water is introduced to the filter, it will never completely dry out.

We hope these tips help you enjoy and use your Sawyer filter safely and to the full extent of its capabilities.
