Woody Binchotan 1pc

Binchotan activated carbon in dense wood which does not float 5the carbons which float are made of low density wood such as eucalyptus which makes them low quality filters) Purifies water naturally!   Woody charcoal is made up of 95% carbon which gives it a unique adsorbent power.   Quality binchotan activated carbon sinks to the bottom of the container and does not float.   Coals that float are considered defective (or are made of very low density and low quality wood).   When coal floats it adsorbs impurities from the air and transmits them into the water while quality coal that sinks does not come into contact with the air and concentrates its activity on purifying the water and not the 'air. 100% reusable, 100% biodegradable Zero waste
