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’s™ 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. If viruses are an issue we offer the PointZERO TWO Purifier™ (0.02 micron absolute pores), the first and thus far only portable purification device to physically remove viruses, which it does 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. Simply put, it is impossible for bacteria to pass through the 0.1 micron filter and impossible for bacteria and viruses to pass through the 0.02 micron purifier.Click through the menu above to learn more about this revolutionary technology.
Helpful Hints for your Filtration System
• If water is very dirty and full of particulate, use a cloth to prefilter the water.
• If water is very dirty and full of particulate, let the water stand in a separate container for a day and then decant the water from the top.
• When using very dirty water, clean the filter after every bucketful or at least daily.
• If water is very dirty and full of particulate, only use 1 foot of hose.
• Do not store backwash syringe in the sun.
• Keep the top of the bucket covered, but not sealed.
• When drilling hole, make sure to de-burr (remove all excess plastic) from the hole. Not having a clean hole can cause a leak.
• If bucket leaks at the fitment, try moving the oring to the inside of the bucket.
• Only run water through the filter and not food products.
