Sawyer Squeeze SP129

How it works

The filter contains a large number of hollow U-shaped microfibers that trap contaminants while allowing the flow of clean, decontaminated water. The pore size is 0,1 microns; meaning anything larger is captured in the microfibers.

The Sawyer Micro Squeeze filter guarantees the removal of 99,99999% of all harmful bacteria (Salmonella, cholera, E. coli, etc.), parasitic protozoa (Giardia and Cryptosporidium), and 100% of microplastics.

Package contents

• Sawyer Squeeze Water Filter (72 g)
• Syringe for backflushing
• 2x foldable bottle with a 1 l capacity and cap
• Inline adapter for connection to a hydration bladder or gravity filtration
• Soft straw
• Mesh stuff sack with a loop (can be used for gravity filtration)

Usage and lifespan

• Simply screw the filter onto a Sawyer bottle or another compatible bottle and squeeze.
• You can drink directly from the filter – it comes with a sports cap (on/off) similar to those found on cycling bottles. Alternatively, you can filter water into a clean bottle.

Compared to the SAWYER MINI filter, it is larger and a few grams heavier, but it offers a faster flow rate (around 2 l/min). The first half-liter of filtered water might be slower, but once the internal fibers are fully saturated, the filter speeds up.

With regular maintenance, the Sawyer Squeeze guarantees a lifespan of over 3 000 000 liters of water.

Maintenance

Protect the filter from freezing. If water freezes inside, it could damage the microfibers. From time to time, backflush the filter using the provided syringe with clean water, flushing in the opposite direction of filtration. Ideally, do this after every trip.

We have used the Sawyer Squeeze filter on many treks, especially abroad. For example, during a trek across Iceland, where sheep contaminated practically all local water sources, the filter was essential.
