Black and Blum Set of 4 Active Charcoal Water Filters

• Natural wood charcoal for authentic filtration
• Zero-waste and biodegradable
• No Plastic, Power or Cartridges required
• Fits most bottles

This set of four activated charcoal filters offers a natural and sustainable way to improve the taste and quality of tap water. Each stick is crafted using a traditional Japanese-inspired method that creates a porous surface to absorb impurities such as chlorine while releasing beneficial minerals like calcium and magnesium. Designed to fit most bottles, jugs, and carafes, these filters are easy to use—simply boil to activate, place in water, and allow time for filtration. Each stick lasts up to six months with a mid-life refresh, providing up to a year of cleaner, fresher water. When finished, the filters can be repurposed as natural deodorisers or added to soil as a nutrient-rich additive, ensuring zero waste.
