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.
We have independent lab tests using EPA protocols and information about our Million Gallon Guarantee that are available on our Downloads Page.
Filtration for Individuals
If you are looking for a filter you will be using for yourself, the following products will be best for you needs.
The Sawyer Mini Water Filtration System is our newest and most popular filter. The Mini weighs just 2 ounces and filters up to 100,000 gallons! You can drink directly from the Mini, attach it to Sawyer Squeeze Pouches, use inline on a hydration pack, or attach it to the top of almost any bottled water? How about that for versatility? And like all Sawyer Filters; they are backflushable almost indefinitely. That means no expensive cartridges to replace, ever. (SP128, SP124)

Portability vs. Stationary
Whether you are filtering on the go or sticking around a while, we have something for everyone. Our bucket filters, when applied to larger buckets, may be better for keeping in one location, while our Squeeze filters are light and always ready to go.
Anyone can use our filters. They are low maintenance and light weight which is perfect for kids going on trips to summer camp or to see the world. They are very easy transport and use.
The Sawyer Squeeze Filter
The Sawyer Squeeze Filter can be used in conjunction with a hydration pack. Please see video Sawyer Squeeze with Hydration Pack using Inline Adapter and Sawyer Squeeze with Fast Fill Adapters.
The Sawyer Squeeze Filter with Water Bottles
The Sawyer Squeeze Filter can also be used on water bottles when you are unsure whether or not it is safe to drink the water.
The Sawyer Inline Filter
This convenient filter can be used as an inline filter on a hydration pack, a pre-filter for an existing pump system, with the provided faucet adapter, or with a gravity bag.
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.
Before initial wetting
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.
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.
