I bought one cheap hot/ambient water dispenser..... use 6mth only spoil already... now I just buy binchotan charcoal from Amazon and put inside water jar.

Does Binchotan charcoal filter water?     Binchotan (Japanese Oak) activated charcoal is the highest grade of charcoal. These charcoals are from the Kishu region of Japan. Excellent natural properties that help reduce odor and hardness from water, and filter for better tasting drinking water. Filtering time is approximately 3-4 hours       thank me later

Msm want us to guess. So we guess
