What we love about Bamboo Charcoal Filters...
Mineralises Tap Water
Can be upcycled after use around your home
An added benefit of using Bamboo Charcoal Water Filters is that it "mineralises" the water during initial usage by slowly releasing minerals - potassium, magnesium, etc. - into the water.
How bamboo charcoal works
Bamboo charcoal's incredible filtering ability comes from its super-porous structure. One gram of high-quality bamboo charcoal has a surface area equivalent of up to three tennis courts. It works like a sponge and absorbs impurities into its pores.
Other woods can be used to make charcoal for filtering water but the larger number of porous cavities in bamboo charcoal is considered to give it better filtering abilities. In fact, three times greater per gram than wood charcoal. As a fast-growing plant, supply is abundant and sustainable.
Tried and tested
Bamboo Charcoal Water Filters are traditional and well-known in many parts of the world. This bamboo charcoal is carefully made in Japan in clay kilns by experienced charcoal makers and is simply of the highest quality of its kind.
How to use your Bamboo Charcoal Water Filters
Use approx: 1 litre jug = 3 - 4 pieces; 2 litre jug = 6 - 8 pieces
1. Wash your Charcoal Water Filter in running water to remove powder (do not use detergent).
2. Boil for 10 mins in a pan of water to sterilise and allow to cool and dry.
3. Place in a jug and fill with tap water (charcoal may float when new but it will tend to sink after a week or so of use).
4. Leave for 8 hours or more for best results. You can leave it in the fridge to chill if you like. It's then ready to drink.
5. Re-sterilise your Charcoal Water Filters once a week by repeating step 2.
6. Replace with new filters after 2-6 months of use.
Upcycling your Charcoal Water Filters
Once their filtering days are over, don't throw your Charcoal Water Filters away. Dry them out in the sun and they can have a very useful second life! Charcoal regulates moisture, reduces odours, inhibits mould and keeps food fresh. Place them around your home in:
Mouldy kitchen and bathroom corners
Places you keep food and fruits (e.g. the fridge, bread bin, fruit bowl)
Smelly places (e.g. the fridge, loo, shoes)
Places you want to keep very dry (e.g. chests of drawers)
Make sure the pieces are completely dry before re-using. If you place them in a mild environment like chests of drawers, you can more or less use forever. In tougher places like the bathroom or the fridge, refresh them by leaving them in the sun for the afternoon and then place them back.
When it's time to say a final goodbye to your Charcoal Water Filter, you can return it to the earth by crushing and burying it in the garden, in pot plants or mixing with compost etc.
As if it hasn't worked hard enough, crushed bamboo charcoal will help aerate the soil and increase water retention, absorb excess moisture when it's wet and release it when dry. Not bad after many months of multi-tasking for you!
