C3U ACF & UF Filtration Water Bottle
This 1.06 L portable filtered water bottle combines the power of ultrafiltration (UF) and activated carbon fiber (ACF) to deliver safe, clean, and better-tasting water wherever your journey takes you. It’s ideal for hiking, travel, emergency use, or everyday hydration from uncertain water sources.
The UF membrane features 0.1 micron filtration precision, physically blocking bacteria, protozoa, and suspended particles without the need for chemicals or power. This ensures that the water you drink is clean, clear, and microbiologically safe.
The ACF filter complements this by adsorbing chlorine, volatile organic compounds (VOCs), unpleasant odours, and bad tastes, resulting in fresh, neutral-tasting water. Together, the two filtration stages provide both safety and comfort, ideal for both outdoor exploration and everyday use.
Both filters are long-lasting: the ACF filter typically lasts around 500 litres or approximately 6 months, while the UF membrane remains effective for up to 4,000 litres or roughly 12 months, depending on water quality and usage. The filter modules are easily replaceable, making the bottle a sustainable and long-term hydration solution.
Constructed from BPA-free, food-grade materials, this bottle is durable, lightweight, and leakproof — built to perform in both outdoor and urban environments. Whether filling from a tap, stream, or rainwater tank, it ensures reliable filtration and pure water every time.
