Conventional water filters are expensive. This is a great(and cheaper) alternative

Binchotan absorbs chlorine and other chemicals from drinking water while releasing natural minerals into it. It has an alkaline effect, thus improving the overall taste of water.

Each stick can be used for about three months. It can easily be recycled by breaking it into small pieces and placing them into your plant soil, or as a dehumidifier.

It takes at least 3-4 hours to filter the water. I like to put them in my bottle before bed, so that it'll be ready in the morning
