OKO Water Bottle

The OKO bottle uses a combination of NanoFiber technology and activated carbon to reduce particulates, chemicals, and heavy metals. It is tested to meet NSF/ANSI 42 and 53 standards, ensuring it effectively improves taste and odor while filtering out contaminants.

The filter cartridge is rated for approximately 400 uses. Depending on the quality of the water you are filtering, you may notice a decrease in flow rate or a change in taste, which are good indicators that it is time to swap in a fresh cartridge.

Yes, the OKO bottle is designed for outdoor use and can filter water from various sources, including streams and lakes. However, it is primarily designed for aesthetic and chemical filtration; if you are in an area with high biological risk, you may want to use it in conjunction with a purification tablet or boil the water first.

The bottle features a high-flow design that allows for a flow rate of 2 liters per minute. Because of the flexible, squeezable body, you can easily dispense water without needing to exert significant effort.

Yes, the OKO bottle is constructed from BPA-free materials, ensuring that no harmful chemicals leach into your water. It is designed to be a safe, reusable, and sustainable alternative to single-use plastic bottles.

With a width of 2.875 inches, the bottle is designed to fit into most standard cup holders, making it a convenient option for travel, commuting, or gym use.
