Write a review


Beautiful results for...

 We love this effective water filtration system from Black + Blum. We first saw this and were impressed by it, on the Lizzie Loves website, where she raved about the benefits, and we are so grateful to her for introducing this to us.

This elegant 1.1 litre / 37 fl oz hand-blown glass carafe that filters your water using a traditional Japanese Binchotan charcoal method for a cleaner, purified taste. 

Ergonomically shaped, this natural glass and cork stopper bottle set, includes one binchotan active charcoal filter (6 months life) and will make your tap water taste great! 

It's Eco, pure and good for you as well as the environment! Never mind the fact it looks fabulous on the table, keeping everyone hydrated on the go. The bottle also conveniently fits in the fridge door shelf too.

The Binchotan charcoal water filters can be added to any water bottle, jug or container. This activated charcoal naturally filters any chlorine, adds minerals and lasts up to 6 months

How it works

Binchotan is an active carbon made from tree branches and is renowned for its ability to soften water, add good minerals and absorb unwanted tastes and odours, such as chlorine. 

Black + Blum charcoal is sustainably sourced from a renewable forest in Laos. It’s burned to up to 1800°F using an ancient method and then rapidly cooled in the earth, producing a very smooth, very dense material that naturally filters water.

If used in just over 34 fl oz of water daily, it will last for 3 months. You can then recharge it by boiling it for 10 minutes, and it will last an additional 3 months.

Is charcoal dangerous if swallowed?
No, it isn’t. Active charcoal tablets are often prescribed to treat a number of different medical issues, like upset stomachs, high cholesterol, and even hangovers..

How to use it

Is the eau carafe dishwasher safe?
The glass bottle and silicone cap are dishwasher safe, but the cork top is not. Separate the silicone cap from the cork stopper before dishwashing.

Do I need to wash the carafe regularly?
When water is left in the bottle for long periods of time, mould spores can form. The binchotan charcoal removes the chlorine from drinking water, so you might notice it forming more quickly than normal. This is nothing to worry about, as long as you refill it with fresh water every few days, clean the carafe and silicone cap regularly and don’t drink stale water that has been sitting in the carafe for more than a few days.

How do I clean the cork stopper?
Cork can darken over time through use. We recommend washing in warm soapy water, to wash away finger marks.
