A closer look at 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 (99.99999%), 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 (99.9997%) 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.




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.

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. Backwash syringe Hose, filter and connector *items not pictured include a filter hanger and detailed picture instructions with room for translation. Hole cutter

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.
