Popular Water Filtration FAQsView All
The Sawyer filter removes taste that comes from bacteria, dirt, and green matter.
The Sawyer filter does NOT remove iron, sulfur, other chemicals, or simple compounds. Taste can be masked by using flavor additives like Gatorade or crystal light (filter needs to be cleaned immediately after using them).
The Sawyer filters are not made with charcoal. While other portable filters have charcoal, they lack in amount of media and adequate dwell time. 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.
+What is the difference between the PointONE™ and Point ZEROTWO™ Filtration Systems and how do I know which to use?
First, Sawyer’s filters and purifiers are rated in Absolute Microns. This means there is no pore size larger than 0.1 or 0.02 micron in size on the PointONE™ and PointZEROTWO™ respectively. This means that it is impossible for harmful bacteria, protozoa, or cysts like E. coli, Giradia, Vibrio cholerae and Salmonella typhi (which cause Cholera and Typhoid) to pass through the Sawyer filters and purifiers. At 7 log (99.99999%) the filter attains the highest level of filtration available today. The PointZEROTWO™ filter removes both bacteria and viruses.
Sawyer PointONE™ Filtration
The PointONE™ filtration system is usually all you would need unless you are traveling internationally (developing countries) where waterborne viruses such as hepatitis and/or Polio are present. This system removes all harmful pathogens from your water.
Sawyer PointZEROTWO™ Purifier
If viruses are an issue, we offer the PointZeroTWO™ 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. Due to the significantly higher level of filtration, PointZEROTWO’s flow rate is considerably slower than the PointONE™ filters.
North America vs. Third World Countries
In North America we do not have concerns about viruses in our water. They simply cannot survive. Viruses derive from contaminated human sewage and die shortly after entering a body of water. In Third World countries outbreaks have occurred due to poor treatment of sewage. Sewage without viruses can be handled by the PointONE™ filter. The only viruses with the potential to survive in water are hepatitis (which is rare) and Polio (which is extremely rare). You can contact CDC for information on virus outbreaks in areas for which you are traveling.

No. Permethrin will not damage clothes or equipment. Unlike DEET, which may harm some fabrics and materials, Permethrin is compatible for use even on fragile fabrics such as silk, plus all synthetics and waterproof membrane fabrics. Permethrin will not affect plastics or finishes. IF IN DOUBT, try a sample on an obscure surface area, especially on delicates and check it after 24 hours of exposure.
Sawyer® Permethrin Insect Repellent is odorless, non-greasy and non-staining after it dries. Permethrin can be harmful to aquatic creatures such as fish, so do not spray Permethrin around fish aquariums.

No. If you are known to be allergic, you should always carry an Epipen® pen. Though the Extractor pump is designed to achieve rapid relief from the pain or itching that comes from a bite; it is not medication.
The pump has been used successfully for over 30 years as a supplement to medical treatments of snake bite and for bee sting venom, targeting initial removal in the field. The victim should ALWAYS be taken to the closest hospital or urgent care facility for further examination and medical treatment.
Popular Sunscreen FAQsView All
If properly applied (1 1/4 ounce per full body coverage) you seldom need more than an SPF 15. See the paragraph below for when you may need more. However, most people put on only half of the recommended FDA standard. An SPF 15 applied at half rate is effectively an SPF 7, better than nothing but still not a true sunscreen. If you can discipline yourself to put on a generous amount, then after it has fully absorbed into the skin, you will benefit by having less chemicals in the skin which allows your skin to breathe easier. If you just can’t bring yourself to lather it on then jump to an SPF 30 which, when half applied, still leaves you with an effective protection of an SPF 15. If you’re sensitive to oxybensone or benzephenone then stick with the SPF 15 which generally does not include that sunscreen.
In planning a trip, use the 1 1/4 ounce per person per day figure as a guideline. If you’re building a tan, or reducing your skin exposure via clothing, then reduce your anticipated need accordingly. Keep in mind that a soaked cotton shirt yields protection equivalent to only an SPF of 4 to 8 only and therefore you may need to wear a sunscreen below the shirt if exposed to water or sweat.
Our Stay Put sunscreen doesn’t have an expiration date printed on it because it is good for 5 years when stored properly.
