Sawyer® Squeeze is a compact, lightweight water filter with 0.1 micron filtration. Although this filter fits in your palm, it removes 99.99999% of bacteria such as E. coli and 99.9999% of protozoa including giardia and cryptosporidium, plus 100% of microplastics. It can be used on plastic bottles and bladders, inline with your hydration pack, in a gravity system, or as a straw. And there’s no pumping required.

Squeeze is the most popular filter on the trail because it has a much higher flow rate and lower clog rate than others. The new water bladder included is lighter yet more robust than previous versions. Though many backpackers have discovered the simplicity of the Vecto Water Bladders that are compatible with the Squeeze Filter.

The input end screws directly on 28 mm threaded plastic water bottles and bladders. Add the cleaning coupling to connect the output end to a bottle or bladder. You can build a gravity filter system by simply attaching a bottle or bladder to each side. Install Inline Adapters to add the filter to your hydration pack or attach the included tube to drink straight from a source.


Use on

  • Plastic water/soda bottles, 28 mm
  • Water bladders, 28 mm
  • Gravity filter systems
  • Inline on hydration packs
  • Direct from the source, drink as a straw


Squeeze has an array of hollow fiber tubes with thousands of tiny 0.1 micron holes in the side wall that block 99.9999% of harmful bacteria, Giardia, E. coli, protozoan cysts, Cryptosporidium and more. All these organisms are too large to fit through the tiny holes. Water is drawn through the side walls of the tubes and down the center of the hollow core while harmful bacteria and protozoa stay trapped on the outside walls of the tube. The tubes are looped to substantially increase the surface area and ultimately the flow rate of the filter.

You can easily backflush the filter to clean out particulate, increasing the lifespan of the filter. Fill the syringe with clean, filtered water and press it against the output hose fitting. Repeatedly force water through the filter backwards. Or, using a Filter Coupling, screw the output end on a plastic bottle or bladder containing clean, filtered water and squeeze to push water backwards through the filter.

Every filter is performance tested 3x to exceed EPA standards for filtration.

Will this work on standard plastic bottles, like Smartwater, LIFEWTR, Aquafina, and Desani?



Will this work on water bladders, like Platypus, Evernew, and CNOC Vecto?



Will this work with hydration reservoirs, like CamelBak?

It fits inline with your hydration reservoir, or you can use it on the end in place of the bite valve. The Inline Adapters will need to be installed for use with a hydration reservoir.


What size tubing will attach directly to this filter?

5/16 in. inner diameter tubing. For use with a hydration reservoir with industry standard ¼ in. inner diameter tubing, add Inline Adapters.


Can I filter cloudy, muddy, silty, glacial stream, or tea-colored water?

Filter the cleanest, clearest water available. Cloudy, muddy, silty, glacial stream, and tea-colored water will clog the filter faster.


Can I filter sea water or chemical-contaminated water?

The filter does not make potable water from sea water or chemical-contaminated water. It does not remove chemicals, pesticides, radioactive materials, or particles smaller than 0.1 microns. Do not filter water from mine tailing ponds or near agricultural operations as they may contain chemicals.


How often should I backflush the filter?

It is recommended to backflush the filter every 10 L to prevent build up and maintain a high flow rate.


When should the filter be replaced?

Replace the filter when the flow rate drops significantly and backflushing after a vinegar soak no longer increases the flow rate.


What happens if the filter freezes?

Water expands as it freezes, so any residual water left in the filter will damage the hollow fiber tubes when frozen. Do not use the filter if water has frozen inside the filter. To prevent freezing in the backcountry, shake as much water out as possible and keep the filter near your body and sleep with the filter.


Can I disinfect the filter in a dishwasher or microwave?

Never use a dishwasher or microwave to disinfect the filter because the high heat will damage or melt the filter medium.


Should I clean out and sterilize the filter before storing?

Clean and sterilize the filter before or after long-term storage to ensure fresh tasting water. To clean out build up, use vinegar. For a more heavy-duty cleaning and sterilization, use bleach.

Vinegar – Place the filter in a bowl/container. Pour undiluted white vinegar into the bowl/container until the filter is totally covered. Wait 30 minutes. Backflush the filter with 1 L of clean, hot water (you should still be able to put your hand in it).

Bleach – Mix a cap full of household bleach, free of dyes or perfumes, with 1 L of water. Backflush the filter with the bleach water. Then backflush the filter with 1 L of clean, hot water (you should still be able to put your hand in it).

Keeping the caps open and mounting it vertical with the flow direction pointing down, let the filter air dry at room temperature. Once fully dry inside, close the cap and store in a cool, dry location.




  • Read, understand, and follow all instructions and cautions before using filter. Improper use increases risk of exposure to harmful microorganisms and increases risk of gastrointestinal illness.
  • DO NOT use to filter sea water or chemical-contaminated water. Filter does not remove chemicals, pesticides, radioactive materials, or particles smaller than 0.1 microns. Do NOT filter water from mine tailing ponds or near agricultural operations as they may contain chemicals.
  • Discard the first few ounces of water on first use.
  • Keep inlet end away from filtered water to prevent cross contamination.
  • DO NOT allow water to freeze inside filter. DO NOT use filter if water has frozen inside the filter.
  • DO NOT use a dishwasher or microwave to disinfect filter. High heat will damage or melt filter medium.
  • DO NOT drop filter. Dropping may damage filtration medium and render it unusable.
  • DO NOT allow use by children without adult supervision.

In no event shall Litesmith, LLC be liable for any direct, indirect, punitive, incidental, or special consequential damages, to property or life, whatsoever arising out of or connected with the use or misuse of its products.
