The EZ Jug proprietary carbon block cartridge is designed and tested to NSF 42/53 standards for high-performance filtration. It effectively reduces chlorine, lead, VOCs, cysts, particles over 5 micron (like microplastics), bad taste, and odor, while helping reduce other common impurities for cleaner, safer drinking water. The filter enhances overall water quality, delivering fresh, great-tasting water every time, and serves as a cost-effective, eco-friendly alternative to bottled water by reducing plastic waste. With a recommended capacity of up to 1,050 gallons (3,975 L) of potable water, it provides long-lasting performance and installs quickly and easily within the EZ Jug Filtration System. It is for use with potable water only and does not reduce TDS (Total Dissolved Solids).
