Key Benefits
- Naturally purifies and improves the taste of tap water.
- Removes chlorine and adds minerals.
- Each filter lasts for up to 6 months.
- With coil made of high-quality stainless steel.
Made from premium Binchotan charcoal, this filter harnesses traditional Japanese methods to purify and soften water. Binchotan charcoal is sourced sustainably from the branches of fast-growing trees in Laos, ensuring minimal environmental impact. The charcoal's active carbon works effectively to absorb impurities like chlorine, leaving water free from unpleasant tastes and odours.
Designed to fit most bottles and jugs, it starts working within an hour and filters 1.1L of water daily, lasting up to three months. When it needs a refresh, simply boil it for 10 minutes to extend its life by another 3 months. Even if it breaks, the charcoal pieces can still be used, making this an easy, sustainable way to reduce waste while enjoying better hydration every day.
This design features a stainless steel coil that securely holds the charcoal filter, ensuring it stays in place while in use.
