Membrane Solutions Replacement ACF Filter for C3 Filtered Water Bottle

Superior ACF Filters: The ACF (Activated Carbon Fiber) filters achieve faster flow rates up to 800ml/min and maintaining 99.9% removal efficiency of chlorine, odors, and microplastics. The 4 stages filtration design enhances particulate capture capacity, ensuring smoother water flow with minimal pressure drop.
Powerful Filtration & Extra Filter: Our ACF filter outperforms traditional CTO filters in every way. No black water, no grit, no compromises – just hydration for your home, gym, or outdoor adventures. Meanwhile, we include an EXTRA replacement ACF filter, providing up to 264Gal/1000L of purified water wherever and whenever needed with filter time-marking ring to rotate to your start month, tracking filter usage.
BPA-Free Materials: Crafted with BPA-free Tritan plastic. And our Tritan filtration water bottle is more shatter-resistant than conventional ones. (PLEASE NOTE: C3 filtered water bottle may require more suction than standard bottles due to its multi-layer filtration system.)
Leakproof & Adventure: Engineered with the leakproof lid, durable handle and anti-slip grip, this water bottle survives rugged trails, gym bags, or car cupholders. The entire water bottle (except the filter) is dishwasher. Enjoy hydration for hiking, camping, or daily commutes.
Filtered Water Bottles for Travel: The water bottle with filter is convenient to carry and can filter water from rivers, lakes, and tap water into drinking water in outdoor conditions, making it the perfect companion for outdoor hiking, camping, and travel.
