How does it work?

How to use a charcoal filter?

Your charcoal is ready to use. Simply fill your bottle/carafe with drinking (potable) tap water and wait for the charcoal to filter impurities from the water. Leaving it overnight is ideal, but you will taste the difference after just one hour. Then, enjoy great tasting water!

How long does it last?

With time, you will notice a decrease in the filter’s effectiveness on the water taste. You can then recharge it by simply boiling it for ten minutes. The boiling washes out the impurities and frees the charcoal up to absorb some more. 

 How is it made?

Sustainably sourced wood is placed in a kiln and charred at a relatively low temperature for some time, then, near the end of the process, the kiln temperature is raised to about 1000 degree Celsius to make the wood red-hot. The charcoal is then removed and quickly covered with a special powder made from earth, sand and ash, and this gives the charcoal surface a whitish hue (explaining the name 'white charcoal'). The rapid rise in temperature, followed by a rapid cooling, incinerates the bark and leaves a smooth, hard surface. If you strike it, you'll hear a clear, metallic sound.

Is it dangerous if I swallow a bit of charcoal?

Occasionally you will notice tiny particles / fragments of the charcoal in the water, but do not be alarmed as it will do you no harm if you swallow them (active charcoal tablets are prescribed to treat diarrhoea, indigestion and flatulence).

Do I need to wash my charcoal?
Your binchotan charcoal is already washed and ready to use. Please do not wash with detergent or soap.

Can I use my binchotan with flavoured water (fruit infused or tea)?
Please do not use with flavoured cordials, fruit infusions or tea.
