My new on-the-go water filter

I’ve learned A LOT lately about the effects of municipal water and the impact it can have on our health. And because of this information I am really aware of the water I consume and its filtration. In fact, I wrote a blog about it over a year ago.

Are you familiar with the water you are drinking?

I cringe when my only option for water is unfiltered tap water but realize in life Better IS Better. I also am very conscious of the impact bottles have on our planet and refuse to go through cases of bottled water. So this leads me to filtering my water at home and using refillable water bottles to take to work. This are the same filters which are akin to water softeners, which make Hard water more potable & sterilize it. To keep your kidneys from not failing anytime soon, it’s better to get a water softener. Peruse some water softener reviews before getting one. The only problem is I prefer to only tote 1 bottle but will drink much more than that.

I’ve been looking for a good portable water filter and think I have finally found one. The eccentric Black and Blum company, known for creating uniquely designed products have created a reusable water bottle (eau good water bottle) and filter for folks like me! I came across this company and product through UD perks and decided to give it a try. The filtration is a piece of binchotan active charcoal (created and utilized extensively in Japan, read more at which actually absorbs chlorine, mineralizes the water, and balances the pH.


Here’s what Black and Blum’s website says about the filter:

How is it made?

Sustainably sourced wood is placed in a kiln and charred at a relatively low temperature for some time, then, near the end of the process, the kiln temperature is raised to about 1000 degree Celsius to make the wood red-hot. The charcoal is then removed and quickly covered with a special powder made from earth, sand and ash, and this gives the charcoal surface a whitish hue (explaining the name ‘white charcoal’). The rapid rise in temperature, followed by a rapid cooling, incinerates the bark and leaves a smooth, hard surface. If you strike it, you’ll hear a clear, metallic sound.

How does it work?

Binchotan charcoal has an incredibly porous surface with tiny cavities oriented in many directions. Just 1 gram has a surface area in excess of 500 m2 (about one tenth the size of a football field). It is also known as active carbon as the ions of contaminants are attracted to the surface of the carbon, where they will be held. It is also able to release minerals such as calcium, iron and magnesium back into the water which enhances its taste and health benefits.

How long will it last?

If you are using your Binchotan with our ‘eau good’ bottle and fill it up once a day, then it should last three months. You are then able to recharge it by boiling it in water for ten minutes and then leaving to dry in sunlight. You should be able to keep recharging it for a further three months.

The Verdict

black-blum-eau-good-binchotan-charcoal-filter-water-bottle-3I’m sold! After the first use I tasted a DRASTIC difference in my water. I used unfiltered tap water from a restaurant. Before filtration, you could clearly taste the chlorine in the water. I only let the water sit in the bottle for a little less than 2 hours and I no longer tasted chlorine. In fact, the water tasted amazing.

The added minerals is a huge perk since as a society we can all benefit from some added trace minerals in our diet and obtaining them through water is a great way. I’ve had this bottle for about a month and it still works as well as it did the first day. After 3 months of using it once a day, you can boil it to remove the chemicals it has absorbed, then use it for another 3 months before having to replace the filter. I use mine more than once a day on most days so I think I will be boiling mine closer to the 2 month mark.

Plus the thing just looks cool. Its a quirky shake and fits snugly in my hand. And lets face it, we like aesthetic things.

There are 2 downfalls with the bottle. First, the way the lid fits. It is not super easy to get on and off. The metal brace over the top can be hard to push off at times. Second, I have noticed the rubber on the cap can get slimy if the bottle is sitting on its side for a long time so that the water is touching it. I just continually wipe it off and keep it sitting upright.

Overall, I am super stoked for this product and will probably be gifting it to some friends and family as well.
