Meet the Membrane Solutions C3 Filtered Water Bottle

A 36oz portable hydration companion designed for everyday use, travel, and outdoor adventures. The C3 bottle combines replaceable ACF (Activated Carbon Fiber) and UF (Ultrafiltration) filters to turn a variety of water sources into drinkable water on the go. Its durable construction and thoughtful design make it a practical choice for commuters, hikers, campers, and road-trippers who value clean-tasting water without relying on single-use bottles.

Six-Stage Filtration for Cleaner Water On the Move

The C3 bottle features a 0.1μm filtration system that works through multiple layers to enhance taste, clarity, and safety. This two-filter core is complemented by a six-stage filtration approach intended to address common water challenges you may encounter away from home.

• 0.1μm ACF+UF filtration tackles diverse water challenges with a multi-layer design
• ACF filter life up to 132 gallons (500 liters); UF filter life up to 1,057 gallons (4,000 liters)
• Filter time-marking ring helps you rotate to the start month and track usage

Certified Performance and Real-World Use

SGS testing and certification cover key standards, with filtration performance demonstrated across a range of conditions. The system is designed for indoor and outdoor water sources, offering flexibility when you’re traveling, hiking, or handling unexpected water supplies.

• SGS tested against NSF/ANSI 42/53/P231 for filtration performance
• Removes chlorine, turbidity, microplastics, and other common concerns
• Laboratory-verified filtration for total coliforms and representative microbes

Durability, Safety, and Everyday Convenience

The bottle body uses BPA-free Tritan for durability and shatter resistance. A leakproof lid, sturdy handle, and anti-slip grip are designed for rugged use on trails, in the gym bag, or during commute. Note that the multi-layer filtration may require a bit more suction than standard bottles due to the filtration depth. The wide-mouth opening supports easy refilling from taps, rivers, or lakes.

• BPA-free Tritan construction emphasizes durability
• Leakproof lid, durable handle, and anti-slip grip for adventure-friendly reliability
• Dishwasher-safe bottle body (filter excluded) for straightforward cleaning

Capacity, Use Cases, and Practical Tips

With a 36-ounce capacity, this bottle is well-suited for long hikes, road trips, and busy days when you want to minimize disposable bottles. It’s designed to filter water from rivers, lakes, and taps into drinking water you can sip confidently on the go. While filtration can enhance versatility, actual outcomes depend on water source quality, usage, and maintenance. It’s a practical companion for outdoor adventures, travel, and daily hydration—presenting possibilities rather than guarantees.

• 36oz capacity supports extended outings and multi-hour activities
• Leakproof design, durable handle, and anti-slip grip for reliable transport
• Wide-mouth filling enables easy outdoors and indoors refills
