Be sure to compare the weight of these charcoal fresheners to other bamboo charcoal products. The number one indicator of effectiveness is the amount of charcoal. The greater the weight, the greater the odor absorbing capability. These can be used in any room of the house, closets, in your car and also work great to control odors in your refrigerator.

Bamboo charcoal has a surface area as high as 600 sq meters per gram, and is excellent at absorbing and trapping harmful substances from the air such as allergens, smoke, odors, and volatile organic compounds (VOCs) from fresh paint or carpet. Our bamboo charcoal is produced at extremely high temperatures to ensure purity, and maximal surface area. Bamboo charcoal naturally emits negative ions and far-infrared rays. The negative ions help balance out the positive ions emitted by electronics in your home, and the far-infrared rays help boost your circulation, reducing soreness and cramps.
