Sawyer × Cnoc Outdoors
Sawyer Squeeze Filter Knokke 1L Bottle
This compact water purification set includes the Sawyer filter, trusted by backpackers around the world, and the lightweight, foldable Cnoc Vesica 1L bottle. It is also recommended for UL-oriented hikers who want to minimize their luggage.

High-precision filtration: 0.1 micron hollow fiber
Sawyer's filtration mechanism consists of a hollow fiber membrane with ultra-fine pores of 0.1 microns, which removes 99.99999% of common bacteria and parasites (such as echinococcus), converting river and lake water into safe drinking water on the spot.

Quick water purification: Pressure filtration using the squeeze method
By pressing the included Vesica bottle with your hand, water is pressurized and filtered quickly through the filter. This model is particularly excellent in water purification speed among the Sawyer series. *Gravity method used by hanging is not supported.

Lightweight and foldable Vesica® 1L bottle
Lightweight design of about 60g. When not in use, it can be folded up small and stored compactly. Made of TPU material, it is both durable and flexible. It can also be used as a standalone water bottle.

Bottle design carefully crafted down to the last detail
The cap is integrated into the main body so you don't have to worry about losing it, and it comes with a strap for easy removal. It can also be connected to other filters such as the Sawyer Mini and Micro Squeeze.

Compatible with plastic bottles and other companies' gear
The filter can be connected to commercially available plastic bottles and Sawyer genuine pouches. It can be customized to suit various situations such as mountain climbing and camping.

No replacement required, high durability of 380,000 liters
One filter can purify up to 380,000 liters of water. The filter fibers are strong and can withstand repeated backflushing, allowing for long-term use.

Maintain performance with simple maintenance
By backwashing the filter with clean water using the included syringe or cleaning coupling, impurities can be removed and the filter performance restored. Regular cleaning ensures a long filter life.
