    Excellent product. I have used it for about 2 weeks and found it is great and providing naturally sweet water. I have followed the instructions on the packaging, which directed that the water be left for 8 hours before drinking. This I do in the evening and let it stay in the bottle all over the night until the next morning. I leave the water and water bottle on the kitchen counter as it seems to work well for me. I did leave it in the fridge on an occassion but found that the chilled water was not suited to me as much as room temperature water is. A really excellent item. I did look into testing the product to see, if it actually did remove the chlorine from the water, by purchasing strips, that you dip into the water. Though, I decided not to go ahead as that would have meant spending more money. I do have a very strong belief that that water is excellent and it just creates a natural sweetness to the water, which I also read in another review, before I decided to go ahead and purchase the item. I decided to buy 2 sticks. As this helps to remove chlorine from 3 litres of water - 1 stick for 1.5 litres of water. Think the item is going to last ages for me as I am the only one that uses it and drinks from the purified water. I really would recommend to anyone else who wants NO chlorine in their water. The taste for me, just shows me how good it is and if water is in a bottle and you remove the lid to quickly smell, there is no smell of chlorine. So all good, really.

    The water in the area where I live has a strong chemical smell when it comes from the tap and for many years I have used a filter jug to be able to drink the water without the awful chemical taste. However I am trying to cut back on my use of plastic and as the filters are also expensive to replace every month I decided to try this charcoal alternative. I was a bit aprehensive as it seemed too good to be true , the filter lasts for 3 months then just needs to be boiled in water for it to last another 3 months, after this time it can be use as a deoderiser for shoes, cat litter etc or just broken up and put on your garden. I am delighted with the resulting filtered water it makes our water taste really sweet and as good as any expensive bottled mineral water and best of all no plastic waste going into landfil every month and its cheaper so it has been win win all round for me. I also had to contact the seller for help and had an immediate, courteous, helpful reply excellent service all round I would highly recomend this product and this seller.

    Got myself one of these because the water here tastes so horrible that I used to use bottled water for drinking. It works like a dream taking out the chlorine and impurities.
    I looked at the hundreds of good reviews and was a bit sceptical but I'm so fed up with plastic crap.
    I'm so happy with it and you can use it for 6 months, after that you can cut it up and use it in shoes to keep them fresh or draws and wardrobes, you can also put bits in plants helps them grow, compost as well or chuck it on the bbq.
    Water tastes better after an hour, tastes great after 4 hours and amazing after 8 hours so I've ordered another one to rotate my big jugs for an all day supply.
    It works, it's cheap, its eco friendly.

    Water tastes great once I added it to our drinking water tank. And it had been horrid before. Britta filters alone couldn't make it better.
    Now this little thing is added and it's delicious.
    One star knocked off because it is pricey.
    Also - one thing to note is that the information here says it lasts six months and can be boiled to reactivate.
    However, the information provided on the packet states that it should be boiled after 3 months.
    So it is left unclear whether it needs to be boiled at 3 months. Also whether boiling it at 6 months will make it last a further 3 months?
    Or at 6 months it is done?

    I just popped it in a steel water bottle which i just use at night, and every night the water doesnt taste of anything, it just tastes of nothing. thats good as teh water quality is generally good but can be variable, sometimes it feels like it has a lot more chlorine than at other times. everyone in the family agrees it tastes better than straight out of the tap. Its definitely better for the env + wallet than buying bottled water, so i highly recommend it. It will rattle around if you are carrying a bottle with you, so best for bottles that are stationary.

    I fell in love with the romantic notion of purifying water following a tradition which is supposed to be centuries old. I bought a glass jar for the purpose. I boiled my charcoal in water to prime it. Then I put it in my glass jar and filled it with tap water. Did it overnight so that the water was cleaned for the eight hours required. Made our teas in the morning - need more water. No, wait - another eight hours? You have got to be kidding me. Perhaps this works in Japan in the countryside where each family has two barrels of water on the go and a mother at home the whole day to top up the water. It is totally impractical for me. In addition, it does not soften the water. I can confirm that the water tastes slightly better than pure tap water, but then again so might water allowed to sit for eight hours, without the filter. There was, disappointingly, still scum on the surface of the tea. So i have given in to modern technology and purchased a standard water filter jug which cleans and softens the water in seconds. The water from the filter jug tastes better than the charcoal filtered water too. We also have no scum on the surface of the water, no scale at all in our kettle and clean cups!!
    So, sorry. Romantic notion, but not up to the task.

    El Binchotan, aunque parezca increíble para quien nunca lo ha comprado funciona. Nosotros buscábamos la manera de no venir cargados de botellas del súper. Primero probamos el sistema de que nos trajesen las botellas de 20 litros con dispensador, pero siempre nos quedábamos sin agua al día siguiente de pasar la furgoneta de reparto. El Binchotan es un simple palo que pones en una jarra llena de agua y pasadas tres horas no sabe a cloro ni nada. Esta ha sido la mejor solución y sin plástico.

    I have been looking for a water filter that does not contain plastic, easy to use, and economical. Ive been using a brita water filter but i hate the fact that the water sits in plastic all the time...... These are great! Reasonably priced, easy to use and taste great! I drink a lot of water. So I purchased a ceramic water crock dispenser that fits nicely on my kitchen counter. I have two glass growlers that each have a charcoal stick in them. I keep those full so they can filter overnight and that way I always have fresh water available to put in my dispenser. I'm so happy I finally have a safe and easy water dispenser. It cost me a one time fee of $40 for crock and then it will be $16 a YEAR for the charcoal(since I use 2 at a time). And after 6 months you can use your charcoal as air purifiers for closets, decoration or to burn! It's awesome!

    Prima finde ich auch die Haltbarkeit (2x3Monate) und die weitere Verwendbarkeit der Kohle als Blumendünger etc. Kein Müll (außer der sehr reduzierten Verpackung), kein Plastik (wie bei anderen Wasserfiltern) und keine hohen Kosten für die Filter...für mich perfekt!
