Q1. My filter has little to no flow. What should I do?
A.1:Initial Wetting - Be sure to slowly squeeze the water through the filter, giving the filter fibers time to fully saturate. The initial flow rate may seem slow but will increase as fibers become wetted which usually takes approximately one Liter of water.
A1.2: Back Flushing Process- To maximize the effectiveness and longevity of your filter, Sawyer recommends back flushing your filter after each outing. The fibers are very robust so please be FORCEFUL in your back flush process. When using the syringe do not be gentle, it will only form paths of least resistance instead blowing out the particulates that may be trapped in your filter. When using the faucet adapter, hold the adapter on the faucet and 'turn the water up' to ensure particle(s) removal.
A1.3: Sanitation- Before storing your filter, Sawyer recommends sanitizing your filter. This process is simple: Back flush filter. Run a standard bleach solution (fragrance free) through your filter (one cap of bleach per quart of water). Let air dry and then store in a cool, dry place OR store wet and clean before using.
A1.4: Non-backflushed Filters - In case you forgot to back flush your filter after your last outing and flow seems to be little to diminished, soak the filter in hot tap water (not boiling) for about an hour and then back flush using hot tap water. REMEMBER to back flush FORCEFULLY! When using the syringe, do not be gentle, it will only form paths of least resistance instead of blowing out the particulates that may be trapped in your filter. When using the faucet adapter, hold the adapter on the faucet and 'turn the water up' to ensure particle(s) removal.
A1.5: Calcium Build Up - (If after above steps your filter still seems to be clogged) Soak the filter in hot tap water for about an hour and then back wash using hot tap water. If this doesn't work, it could be dried calcium. Soak the filter in vinegar for 1/2 hour and then flush with hot water. You may have to repeat this a few times to get it all the way clean. Make sure you back flush with all the force you can - hold the faucet adapter on the faucet and turn the water on. The filters are tough and can take more force than you can give with the faucet adapter.
Q2. My pouch seems to be leaking water (holes in seams), how do I prevent this from happening in the future?
A2.1: Initial Wetting - It is usually not the pouch causing the leak, it is usually the filter. Either the filter was not completely wetted at first point of use or too much pressure has been applied to pouch during filtration process. Be sure to slowly squeeze the water through the filter, giving the filter fibers time to fully saturate. The initial flow rate may seem slow, but will increase as fibers become wetted.
A2.2: Back Flushing Process- Back flush your filter (better and more often) using your syringe. You cannot hurt the filter fibers, so please be FORCEFUL in your back flush process. When using the syringe, do not be gentle, it will only form paths of least resistance instead of blowing out the particulates that may be trapped in your filter.
A2.3: Filter Application - Do not over tighten the filter on the pouch. Over tightening can cause the o-rings to embed into the threads or lodge into the opening of the pouch. If the o-ring is out of place you may not a have a tight seal and water could leak out the bottom of the filter. Please watch our video on Important Squeeze Filter Tipsto better understand how to care for your squeeze bags. Until you learn the perfect balance of force and cleaning, we recommend bringing a backup pouch with you on your trip.
A2.4: Torn Pouches- Before the pouches leave the factory they are 100% air tested. While they are rugged, these pouches are not indestructible. They tear as a result of too much pressure being applied and this happens when water is forced through the filter too fast or your filter needs cleaning and is creating more resistance.Â Do not squeeze the pouch as hard or wring the pouch. Torn pouches are not covered under the warranty.
Q3. Does the Sawyer filter remove taste, chemicals and heavy metals form water?
A3.1: Taste- The Sawyer filter removes taste that comes from bacteria, dirt, and green matter.
A3.2: Chemicals- 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).
A3.3 Heavy Metals - 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.
Q4. 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 impossiblefor 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.
A4.1: 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.
A4.2: 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.
A4.3: 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.
Q5: How fast should the water come out of my filter?
A5:Flow rates - vary depending on how clean the filter is and how well you cleaned the filter. Altitude also affects the flow rates (the higher you go the slower the flow. Also, the PointZEROTWO™ filter flows much slower that the Point ONE.
Q6. How do I care for my filter during freezing weather?
A6.1: Before initial wetting - Filter is safe from freezing temperatures if it has never been wetted.
A6.2: After initial wetting- While there is no definitive way to tell if a filter has been damaged due to freezing, Sawyer recommends replacing your filter if you suspect that it has been frozen.
A6.3: During trips - If you are in freezing temperatures we recommend that you store your filter in your pocket or close to your person so that your body heat can prevent freezing. THERE IS NO WARRANTY FOR A FROZEN FILTER
