Individually Tested 3 Times

Every Sawyer filter is performance tested three different times during the manufacturing process to ensure every Sawyer filter is 0.1 absolute micron and that no harmful pathogens can pass through the filter.

Protected Fibers

Our hollow fiber membranes are fully encased and sealed to keep them protected against physical damage or the potential of harmful pathogens to pass in cross contamination.

Absolute Filtration

No pore is larger than 0.1 micron in Sawyer Filters, meaning no harmful bacteria, protozoa or cysts can pass through. Sawyer will not use average or nominal pore size ratings where larger pore sizes are present.

Field Maintainable

Sawyer fibers are ~75% stronger than fibers of other typical hollow fiber membranes allowing for aggressive backwashing and shock resistance. Meaning each Sawyer filter can be continually backwashed forcefully restoring up to 98.5% of the original flow rate.

Frequently Asked Product Questions

How often should I backwash my filter?

We recommend backwashing your filter when you flow rate begins to diminish, before prolonged storage, and when you are ready to start using your filter again. Backwashing your filter after storage is a great way to re-wet the filters and restore the flow rate before use.

How fast should the water come out of my filter?

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.

How do I care for my filter during freezing weather?

Your Filter is safe from freezing temperatures if it has never been wetted.

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.

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.

Does the Sawyer filter remove taste, chemicals and heavy metals from water?

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).

Heavy Metals
The standard 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. For the removal of heavy metals, see our Select Series S3.

Do you have more information about Sawyer’s Label Claims and Warranties?

We have independent lab tests using EPA protocols and information about our filters and their warranties available on our Resources Page.
