Even if water is crystal clear, it could be full of harmful unseen particulates. That is why we offer the highest quality of filtration available, seen our products like the Sawyer Squeeze Filter. As the lightest filter on the market, it can be rolled up in a pack and takes up very little space, making it ideal for camping and traveling. Sawyer water filters also offer the highest level of filtration on the market today due to Sawyer’s water filtration technology. Sawyer’s hollow fiber membrane water filters are comprised of U-shaped micro tubes that allow water to enter into their core through tiny micro pores while trapping bacteria and protozoa on the outside. The high volume of these tubes creates a huge surface area, which results in a very high flow rate and less cleaning. Depending on the type of water you are filtering, you may need to clean your filter more often. You can do this with the simple cleaning syringe included for easy cleaning in the field. The Sawyer Squeeze filter is extremely durable, but it isn’t indestructible, so avoid extreme pressure or wringing the pouch. Just to be safe, make sure you bring a spare pouch with you when you are first using it.
