Using technology taken from kidney dialysis, Sawyer® water filters use Hollow Fiber Membranes. Our filters are comprised of tiny “U” shaped micro tubes that allow water to enter into their core through tiny micro pores. The PointOne Filter pores are so small (0.1 micron absolute) that no bacteria, protozoa, or cysts like E.Coli, Cholera and Typhoid can get through. At 7 log (99.99999%) the filter attains the highest level of filtration available today and yet it has a very high flow rate due to the large amount of tubes. Each filter is certified for ABSOLUTE microns. That means there will be no pore size larger than 0.1 microns in the biological filter Simply put, it is impossible for bacteria to pass through the 0.1 micron filter.

Sawyer made it as simple as it gets. 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 in literally minutes to locally found containers. The kit includes everything you need to attach the filter to any plastic bucket or container. (Bucket not included)

Cleaning Instructions for Sawyer Bucket Adapter Kits


  • Obtain a clean bucket or plastic container
  • Use the hole cutter to drill a hole 1.5 inches from the bottom of the bucket (you can do this by hand).
  • Screw the connector, hose and filter onto the bucket.
  • Fill the bucket with water from any source, lower the filter head below the water line, and let gravity do the rest.

  • +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.

  • +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.

  • +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.

    To estimate the flow rate of your filter based on the altitude where you will be filtering water and the inches (or centimeters) of head pressure:
