Product information

-  Charcoal filter to filter water by absorbing impurities such as chlorine plus add minerals

-  Each charcoal will last for 6 months as a water filter

-  Recyclable for other household uses

This active charcoal is used to filter water by absorbing impurities (such as chlorine), and add minerals (such as calcium). It has been used by the Japanese for over 500 years and will make your tap water taste great. This range was created to encourage people to stop buying expensive bottled water and adding to the continuing single-use plastic global environmental problem. 

These charcoal refills are pre-washed and vacuum sealed so they are ready for immediate use. Simply drop the charcoal into your water, we recommend one stick per litre, then leave for 1 hour and enjoy your filtered water. Each charcoal will last for 6 months as a water filter, and they are then recyclable for other uses around the home e.g. if you break it up and put it in your house plants, it will add nutrients to the soil that will help the plant to grow.

Really Does Work

I hate tap water so spend a fortune on bottled water.... the charcoal filter really does work, after an hour the water is better but if you can leave for 3 or 4 hours it is perfect... would recommend

Easy and Recylable

Bought this to use with my filter jug instead of cartridges, which are expensive and not easy to recycle. Taken top container and lid off. found a plastic lid (Tupperware) which fits well. charcoal stick sinks to bottom in half an hour, works a treat. know water is clean by the smell (no Chlorine). now have second jug, brilliant.

Tasty Tap H20

Keen to not drink bottled water but afraid my tap water is not pleasant tasting I thought these bottles and charcoal filters an excellent solution. I have 2 bottles going all day. Once you get the hang of putting the charcoal in - drop the largest end in first and settle that end opposite the "nose" only then give the bottle a squeeze. Holding the bottle, tilt the top end of the charcoal into the nose and release. It doesn't have to fit in perfectly to stay in place. Tip - try when you're not in a rush. Makes my tap water taste so much better. Thanks for stocking this system Ocado.
