Charcoal water filter sticks // small
Our charcoal sticks are handmade in Japan from Kishu binchotan (also called white charcoal) which is the highest quality charcoal you will find.
Our small charcoal sticks are perfect for putting into your water bottle so you always have fresh water wherever you go.
How to use:
- Put a charcoal stick in your water bottle and fill it with tap water. The stick begins to filter the water immediately and you will notice a difference in taste after just one hour!
- 100% kishu binchotan charcoal
- 2-pack // 10 cm x 1.5-2 cm (3.9 in x 0.6-0.79 in). Each stick purifies up to 1 liter of water at a time.
- Boil your Kishu Binchotan water filter stick for about 5-10 minutes every 3 weeks to keep its pores open. Allow it to dry for about 30 minutes before reusing.
Replace your charcoal stick every 3-4 months.
