Binchotan Charcoal Water Filters at a Glance

If you’re thinking about investing in a Binchotan charcoal water filter, Black + Blum offer some of the best ‘ready made’ options on the market.

Alternatively, it’s also remarkably simple to make your own Binchotan water filter in just a few easy steps. I show you how below or you can check out an in depth tutorial here.

What is Binchotan Charcoal?

Binchotan active charcoal has been used in Japan as a water purifier since the 17th century.

Made in the Kishu region of Japan, it is raw wood turned into charcoal sticks through a process of burning oak branches at extremely high temperatures and then rapidly cooling and smothering the flame with dirt.

This process carbonises the wood and leaves endless tiny cavities that are are able to trap unwanted pollutants.

How Does Binchotan Charcoal Filter Water?

The porous surface of Binchotan charcoal pulls pollutants such as chlorine out of tap water. It is regarded as as the highest quality of activated charcoal for purifying water.

The key benefits of using Binchotan charcoal to filter drinking water include:

  • the charcoal’s alkaline qualities soften and improve the taste of tap water
  • it reduces chlorine
  • it mineralises the water, adding important minerals such calcium, potassium and magnesium
  • it balances the pH of the water.

How To Make Your Own Binchotan Charcoal Water Filter

It’s also really easy to set up your own water filtering process using Binchotan charcoal.

This is actually something I have done myself in my own kitchen using one of these glass Kilner jars with a tap and a stick of Binchotan charcoal.

Simply follow the steps below to make your own homemade Binchotan water filter:

  1. Purchase some Binchotan Charcoal (it’s both inexpensive & easily available online.)
  2. Boil a stick of Binchotan charcoal for 10 minutes in a pan. Allow to cool.
  3. Place the Binchotan stick in a pitcher, or jug, containing tap water and leave to sit for around 4-8 hours, or overnight, to allow it to absorb contaminants and mineralise the water. I recommend using a glass jug or container of a size that suits your needs. For example, I use a Kilner glass dispenser, which works really well for me as it provides enough water for drinking and cooking throughout the day.

It’s recommended you re-boil the Binchotan stick every month or so and use a completely new charcoal stick approximately every 3 -6 months. The beauty of Binchotan charcoal sticks is that after you have used one to filter water with, you can then re-use it by placing it in the fridge to absorb smells or simply compost it in your garden.

To make an inexpensive Binchotan charcoal water filter pitcher or portable water bottle yourself why not try popping a piece of Binchotan charcoal into your favourite water jug or personal water bottle for a freshly filtered water supply at home and or on the go?
