Let's discuss any questions you might have about KURO-Bō.
WHERE TO FIND KURO-Bō
WHAT TO EXPECT
No, because the fluoride molecule is so extremely small, it doesn’t actually bond with the KURO-Bō stick in any significant way.
Just like our KURO-Bō product, the KURO-Bō packaging is all 100% biodegradable and recyclable!
KURO-Bō Activated Charcoal is made using an indigenous hardwood from Laos, and the branches are harvested from forests that are carefully maintained and managed by experts.
The reason activated charcoal is also called ‘white charcoal’ is because, during the creation process, it is covered in a mixture of earth, sand and ash, which gives it a temporary whitish hue – and this has led to it also being known as ‘white charcoal’.
You’ll find one stick of KURO-Bō Activated Charcoal per package, which you can use for up to three months.
Not weird at all actually. Most sticks of KURO-Bō won’t float, although if it does, it just means it’s a little more porous than others, but it won’t make any difference to the filtering process (i.e. its adsorption capability). And just to pre-empt your next question – yes – you can drink from your water container while your KURO-Bō stick is still in there!
Well… Let’s just say stick to filtering water for now, shall we?
The good news is: yes, it will! In fact, it can significantly improve the taste of the tap water, by removing toxins and enriching it with beneficial minerals.
Although Binchotan is known to remove a number of chemicals, viruses and bacteria, we definitely don’t recommend using it to filter untreated water. Stick to using it for filtering drinking tap water instead.
Yes it will. In fact, many people like to add a KURO-Bō stick to their bath to remove toxins and benefit from the enriching minerals it releases. The Japanese have been using binchotan for centuries in cooking rice as it removes impurities in the water and helps retain the taste of the rice.
Do not fret! As activated charcoal sticks are uniquely 100% natural and every tree/branch has its unpredictability and nuances in terms of structure, grain and porosity, fractures can and will happen. This is absolutely fine (albeit the stick looks different!) and will in no way affect the filtration and mineralisation efficacy, or 3 month longevity of the charcoal.
KURO-Bō is proven to remove significant levels of toxic heavy metals and chemicals like: lead, aluminium, copper, iron, chlorine, mercury and manganese, as well as E. coli (tested at 99 CFU per 100ml). Plus research also widely suggests that activated charcoal helps to remove many other impurities such as viruses, other bacteria, pesticides, cancer-related Total Trihalomethanes (TTHMs), chemical run-off, pharmaceuticals and antibiotics, as well as ethylene, acetic acid vapour and hydrogen from the atmosphere. Apparently it can even absorb electromagnetic waves and radio frequencies!
KURO-Bō enriches water with many of the beneficial minerals that were originally stored in the living hardwood tree from which it was created. These include Magnesium and Calcium, and it neutralises pH as well. Binchotan is also known to releases Potassium and Phosphorus.
Absolutely not. Don’t forget that KURO-Bō is natural and nearly 100% solid carbon. Charcoal is by nature, black and a little dusty. Any small residue on your fingers will quickly wash off, and the boiling process removes the other surface residue. Once it begins filtering, nothing at all will be released into the water and, don’t worry, your KURO-Bō stick will never, ever dissolve. There may be a very small amount of flaking, but this is completely harmless.
HOW IT WORKS
Yes, it is possible. But, in keeping with KURO-Bō’s 100% natural and recyclable ethos, we do recommend using glass containers instead. You might want to take a look at our beautiful, hand-blown 100% recycled carafes.
The KURO-Bō stick actually begins filtering water immediately, although for best results, we recommend allowing it to rest for at least 6 – 8 hours, or overnight, either at room temperature or in the fridge.
The longevity of each KURO-Bō stick depends on the quality and the quantity of the water being filtered. So we suggest sticking to a schedule of reactivating your KURO-Bō stick once a month – and, if you find (sooner than later) that your water no longer tastes as clean and fresh as it should, you can always boil your stick for another five minutes, or if you are in the third month, replace your KURO-Bō stick a little sooner. It’s a natural product, so trust your instinct!
Nope. The preliminary boiling stage will remove the light black residue, and because the toxins in the water bond to the KURO-Bō stick at a molecular level, any impurities will remain attached for as long as you use it.
We recommend one Regular stick of KURO-Bō per every 2lt of tap water.
Just 10 minutes is all you need to activate – and reactivate – your KURO-Bō stick each month.
You can keep your KURO-Bō filtered water in the fridge – or out. It just depends on how chilled you like your water really… In fact, many users like to keep a couple of sticks in their 4 litre fridge water dispensers (see images on the How to Use page).
Not unless you like wasting money… With KURO-Bō Activated Charcoal there’s absolutely no need to buy other expensive (or plastic) water filters. Just one stick of KURO-Bō can give you delicious, 100% naturally purified, filtered water for up to three months!
It does, but in a good way. KURO-Bō Activated Charcoal actually helps to balance the pH, thereby softening the water and improving its taste.
Simple! During KURO-Bō’s creation process, it becomes carbonised, as well as highly porous, which significantly increases its surface area, which in turn allows it to adsorb and naturally bond with toxins, in order to remove them, while enriching water with beneficial minerals. This means it acts as a natural filter and improves the taste of your ordinary tap water.
Providing you are following our KURO-Bō Lifecycle Guide, if your water doesn’t taste as clean and refreshing as it should at any stage, it likely means it just needs a little boost! In the first and second month, just try boiling your stick again for 5 minutes to open the pores again. In the third month, it likely means it’s time to recycle and replace!
Absolutely not! One of the best things about KURO-Bō is that it is 100% recyclable. So even though you’re not using it to purify water any more, you can still use it in any number of fantastically useful, eco-friendly ways!
Not at all! Aside from reactivating it once a month to keep the KURO-Bō stick’s pores open, simply keep your KURO-Bō stick in your water jug, carafe or bottle, and let it work its magic.
While this will depend on the volume of water being purified, as well as the quality of the water, you can in fact use a single KURO-Bō stick for up to three months!
