Wash in running water to remove charcoal powder (do not use detergent). Use our bespoke bamboo filter brush to scrub the inside of the charcoal filter.

Place your filter in a pot of water and bring it to boil. Boil for 15 minutes to sterilise the charcoal filter then remove it carefully allowing it to cool and dry. Please make sure to bring the water to boil with the charcoal filter inside the pot and do not add it in once the water is boiling as this can lead to cracks or breakage of the filter. If this occurs, don’t worry—the filter will still work fine.
Place your bamboo filter in a jug or bottle, fill it with up to 2 litres of water then wait for at least 4 hours before drinking.
Reset your filter every two weeks by boiling it for 15 minutes (step 2).
Replace with a new Natural Filters charcoal filter after three months of use.

Recycle your charcoal filter by adding the charcoal directly into your garden to aerate the soil, increase water retention, absorb excess moisture when it’s wet and release it when dry to help your plants grow big and healthy. Check out this article for a full list of various uses in your garden. You can also use your spent charcoal filters to neutralise odours or dampness in your closet, drawers or fridge. Just make sure to first dry the charcoal filter in the sun.
