What makes it Mighty?

  • Binchotan Charcoal from sustainably harvested wood
  • incredibly porous charcoal attracts ions of contaminants and retains impurites
  • releases minerals such as calcium, iron and magnesium back into the water which enhances its taste and health benefits

Product Details

black+blum’s charcoal water filter sticks are a natural and easy way to improve the taste of your drinking water. Simply fill your bottle with (potable) tap water and wait for the charcoal to filter out impurities. You will taste the difference after just one hour (and get even better results if you filter overnight). 

It may seem counter intuitive to purify your drinking water with a stick of charcoal, but the Japanese have been doing it for centuries. Binchotan charcoal 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 odors, such as chlorine. Binchotan charcoal has an incredibly porous surface with tiny cavities. The ions of contaminants are attracted to the surface of the charcoal and are held there. At the same time, the charcoal releases minerals such as calcium, iron and magnesium back into the water which enhances its taste and health benefits. 

  • makes tap water taste great
  • lasts for 6 months (boil to renew effectiveness after 3 months of use)
  • vacuum foil packed
  • pre-washed and ready to use
  • can be used in any jug or bottle

Size: 4.7”

My tap water tasted like mold
Review by Lynn Fricker on 9/3
My tap water tasted like mold

Then I left it in the fridge overnight with one of these bad boys and Bam! Brand new water! These are magic. If you have craptastic water, because you live in one of America's wonderful one employer towns that can't upgrade anything, get these.

Works amazingly

Works amazingly

My use for this might be a little unconventional BUT it’s a game changer. My well water is high in iron and I put this is a gallon jug and let it filter 24 hours and it removes the iron perfectly. I use this in an ice machine for my tie dye business. It saves me so much money not having to buy filtered water (and kinder to the Earth). Definitely buying another one!!

It Works

It Works

This really works! I already use a water filter pitcher, but this makes the water taste so much crisper and cleaner. It's a dramatic difference.

Best tasting water in years!

Best tasting water in years!

These are the best filters I hgv ave ever tried! We gave water filters for our home and also in the refrigerator, so I thought we were getting good filtered water! Once I put this filter in my water bottle it was amazing how much better the water was! I use to gave those white floating particles and a white film on the bottom of the bottle, no more with the charcoal filters! The water now reminds me of the wonderful pure spring water I drank as a child, absolutely wonderful!

Great product!
Review by Amanda on 3/26
Great product!

I really enjoy the charcoal stick! I placed it in a jug that takes filter cartridges and I keep refilling it. The taste of the tap water is just as if I ran the water through the jug with the name brand filter. I'm happy to find this because it greatly cuts down on the plastic and waste from the traditional name brand monthly filters!

Love these
