  • +How long does the filter/purifier last?

    Since the filters and purifiers can continuously be backwashed and re-used they have an extremely long life. The filter/purifier membrane may never need to be replaced, however when the flow rate slows or the filter clogs, simply backwash the unit with the provided backwashing device to clear out the pores.

  • +My filter has little to no flow, what should I do?

    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.

    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. Do NOT use soap when backwashing your filter.

    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.

    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.

    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.

  • +My pouch seems to be leaking water (holes in seams), how do I prevent this from happening in the future?

    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.

    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.

    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 Tips to 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.

    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. This happens when water is forced through the filter too fast or when your filter needs cleaning, which creates more resistance. Do not squeeze the pouch hard or wring the pouch. Torn pouches are not covered under the warranty.

  • +What do you mean by 0.1 and .02 micron absolute?

    Many other filters list nominal or average pore sizes which leave the possibility of harmful pathogens to pass through. By claiming absolute microns there are no variances in pore size on our filter membranes. At 0.1 and 0.02 micron absolute these are true barrier filters so there is no questionable time period whether the water is safe to drink.

Sawyer 2 Liter Complete Water Treatment System

Fast Fill Adapters for Hydration Packs

Sawyer Complete 4-Liter Dual Bag Water Purifier System is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Saved the day for 71 plus in TACLOBAN I purchased filtration system for my son who was going to serve a 2 year mission in the Philippines. (Islands of Leyte and Samar) He was in the eye of Super Typhoon Haiyan (local name Yolanda) and although he lost most everything he was able to keep this filter system intact. After walking for over 20 miles to Tacloban to fly out, the clean water supply was running very low. He was able to use this system to help over 71 missionaries obtain fresh water for a number of days. It was the only filter system they had except two small personal water systems and the concerns were that those filters had already exceeded their charcoal filter capacity. My son reported that the flow was good and that they were able to keep everyone with clean water. Strong recommendation from him! He left it behind to help others and we have purchased another one for him in case he needs it again as he decided to stay in the region to assist others.
