Discover Binchotan charcoal
Binchotan charcoal is a Japanese product, made since the Edo era in the 17th century. It is made from the branches of Ubamegashi, a typical Japanese holm oak with a wood so dense that it does not float.
The Binchotan used for water purification requires a very special carbonisation process. In the end, the carbon content of Wakayama Binchotan is 96%. It is considered to be the purest in the world and is now part of the cultural heritage of the land of the rising sun.
These pieces of charcoal are said to remove the taste and smell of tap water, while purifying it. It is therefore a zero waste alternative to plastic bottles.
Special features of Wakayama Binchotan charcoal
Chamarrel offers you natural Binchotan charcoal sticks from Wakayama. More powerful than recomposed charcoal cartridges, they capture and retain unwanted molecules from tap water. That's why it seems so light and more palatable.
Binchotan sticks are positively charged. They attract negative ions that get trapped in the multiple pores of the charcoal. This way, they "suck out" chlorine, limescale, heavy metals, pesticide, sulphur and drug residues, without releasing them into the water. They are also recommended for purifying baby bottle water to avoid plastic bottles.
How to purify tap water with Binchotan charcoal?
Run the piece of charcoal under water to activate it. Then let it boil in a pot full of water for at least 15 minutes. This will sterilise it. Leave it to dry in the open air and only when it is completely dry can you put it in your one-litre container (bottle, carafe, flask, etc.) filled with tap water.
The litre of water is only purified after about 8 hours. You can therefore use it 3 times a day. The water can be stored in a cool place or at room temperature.
Binchotan charcoal will break the chemical bonds around the molecules it absorbs. It is therefore recommended to boil it once a month to "clean" it, or even weekly if you are using the water for babies or frail people.
The Binchotan charcoal stick can be reused for a period of 6 months. After that, it is considered saturated and should not be used again. You can leave it in your fridge: it will capture bad smells, or throw it in the compost.
Precautions for use
It is not recommended to leave the charcoal in the same water for more than 48 hours. It cannot be used to purify non-drinking water either.
If you do not use your charcoal stick for some time, let it dry and store it away from moisture. The original pouch is perfect for storing it, if you no longer have it, use a glass jar.
Frequently asked questions
My charcoal stick has broken, what should I do?
You can continue to use it in the same way. This has no effect. However, make sure that you always put both pieces in your 1 litre container. If you are undergoing medical treatment, rinse the charcoal pieces and re-boil them before further use. This will prevent lumps of charcoal from being present in the water.
There are charcoal particles in the water, is this worrying?
Not at all! They can be ingested without any danger to your health or that of your family. However, if you are under medical treatment, ask your doctor's advice, as charcoal can reduce the assimilation of medication.
I am going on holiday, can I take my Binchotan with me?
Of course you can! However, be sure to let it dry for 24 hours beforehand and to transport it in a clean, airtight jar. Just let it boil before use.
Can I make my tea or coffee with Binchotan filtered water?
Yes, you can! The flavours will be even better! You may even rediscover the true flavours of your hot drinks. The purified water is also free of limescale, so it won't cause limescale build-up in your household appliances (coffee maker, teapot, kettle, etc.).
Can I give filtered water to my pets?
Yes, without any problem! It is low in calcium and will therefore be beneficial for your castrated animals or those with kidney problems.
