The PureBlock Water Filter Cartridges are designed with a carbon block filter made of food-grade coconut shell carbon block, dense PP food-grade non-woven fabric, and PE outer net.
This filtration system is typically utilized as the third stage in water filtration setups to effectively eliminate residual chlorine, chemicals, VOCs, and bad tastes from various water sources.
The inclusion of food-grade materials like coconut shell activated carbon ensures high iodine adsorption capacity, while the PP non-woven fabric prevents carbon powder leakage, thereby enhancing the longevity of the filter and safeguarding against re-contamination of filtered water.
Additionally, the cartridges are compatible with NSF/ANSI 42 certification standards and are BPA-free, ensuring safety and healthiness for users.
