Authentic Kishu Charcoal – To Go for Water Bottles. The Only Authentic, Certified & Tested Charcoal Water Purifier. Made by Japanese artisans. Absorbs toxins in tap water.Compact by Design (Amazon-developed Certification)

I use a purifying water pitcher at home. This may be a bit much, but I like to also stick the charcoal inside the pitcher for added purification. I personally feel like it makes the water taste even purer.

I love these things! They clean so much out of the water that I drink. I feel so much better mentally knowing all the things that have been pulled out of it. And after a month I just boil it and keep going. They really help so much. I feel better physically after drinking clean water. A really great product

All my tap water now is filtered through the charcoal in my glass jar. I hope it does what it's supposed to. Lol

Buy with confidence; boil once a month and enjoy peace of mind while sipping your water. Enjoy.

I love this product. The water has a noticeably better taste, and I love that you can tell when it’s time to replace because it stops bubbling. It lost a star because tiny pieces of the wood chip off into the water, which is not a huge deal for me. Other than that I love this, boil it 1x a month and it’s like a brand new filter all over!

My water tastes crisp and clean.

Bought for a high school student who if very picky about his health and he wanted something to take on band tour to have good tasting water. He didn't think it did much.

These work well to make drinking water taste clean & delicious. I bring one or a half of one everywhere so that I can refill my water bottle anywhere anytime. I don’t buy overpriced water in plastic waste anymore.
