Sawyer Squeeze Water Filter with Cnoc 1L Bottle — 0.1µm Hollow-Fiber, Backwashable

The Sawyer Squeeze SP302 paired with the Cnoc 1‑liter bottle is a compact, reusable hollow‑fiber water filtration system that produces safe drinking water from lakes, rivers, and taps without replacement cartridges.

This all‑in‑one kit combines Sawyer’s proven 0.1‑micron hollow‑fiber membrane with a soft, collapsible Cnoc bottle to give backpackers, travelers, and emergency planners a durable, lightweight way to filter out bacteria, protozoa, cysts, sediment, and microplastics. Independently tested and individually verified during manufacturing, the system is designed for ease of use: fill the bottle, attach the filter, and drink or squeeze filtered water into another container. Built for repeated field use, the filter’s thicker fiber walls allow aggressive backwashing to restore flow and extend service life.

What contaminants does this filter remove and how reliable is the protection?

The Sawyer Squeeze uses absolute 0.1‑micron hollow‑fiber membranes that physically block bacteria and protozoa and remove tiny particulates like microplastics. Performance is verified by third‑party laboratory testing and by Sawyer’s three individual tests per unit during manufacturing. It’s a mechanical barrier, not a chemical treatment, so it does not rely on consumable cartridges.

• Removes 99.99999% of bacteria (e.g., Salmonella, E. coli)
• Removes 99.9999% of protozoa (e.g., Giardia, Cryptosporidium)
• Removes 100% of microplastics and sediment via 0.1‑micron absolute pores
• Independent lab verification and triple unit testing during production

How do I use and maintain the squeeze system in the field?

Using the system is straightforward: fill the Cnoc bottle from a water source, screw or attach the Sawyer Squeeze to the bottle, then drink directly or squeeze filtered water into another container. Routine maintenance is simple backwashing with the included syringe and cleaning coupling to restore flow when needed. No filter cartridges are required, and the membrane is designed for long‑term reuse.

• Fill bottle from stream, lake, or tap; attach filter and drink or squeeze
• Backwash with included plunger to recover up to 98% of flow
• No cartridges to replace — one membrane lasts up to 100,000 gallons
• Fully enclosed fiber design reduces risk of damage and contamination

How durable and travel-friendly is the Cnoc bottle and Sawyer filter combo?

The Cnoc bottle is made from flexible, BPA‑free TPU that compresses for packing yet stands upright when filled, and the Sawyer membrane has reinforced walls for increased toughness. The complete kit weighs under five ounces, making it one of the lightest hydration filtration options for backpacking and international travel. Sawyer backs the product with a lifetime warranty against manufacturing defects.

• Soft, collapsible 1‑liter Cnoc bottle packs flat when empty
• TPU construction is BPA and PVC free for safe repeated use
• Hollow fiber membranes engineered up to 75% stronger than standard models
• Kit weight under 5 ounces, ideal for ultralight packs and kits

How long will the filter last and what about replacement parts?

The hollow‑fiber membrane is rated for up to 100,000 gallons of treated water when properly maintained, with aggressive backwashing restoring most flow after clogging. Sawyer units are designed without replaceable cartridges; instead, the long‑life membrane and included cleaning tools extend usable life. The company tests each unit multiple times in production and provides lifetime support for defects.

• Rated for up to 100,000 gallons with routine cleaning
• Aggressive backwashing can restore up to 98% of original flow
• No disposable cartridges — lower long‑term waste and cost
• Lifetime warranty covers manufacturing defects

Who is this for: The Sawyer Squeeze SP302 with the Cnoc 1‑liter bottle is aimed at hikers, international travelers, bushcrafters, emergency preppers, and humanitarian aid users who need a lightweight, high‑performance filtration solution without consumable cartridges. It suits anyone who wants a compact, independently tested system that treats biological contaminants and microplastics, fits into an ultralight pack, and can be maintained in the field with minimal tools.
