About Carbon Blends

Our standard “EXEC” carbon blend has a very large internal surface area and works exceptionally well for a wide range of air pollutants. 


The “Vocarb” carbon blend is our most recommended and best-selling specialty carbon blend. Vocarb stands for Volatile organic compounds or VOCs and this include a variety of chemicals that can cause a range of health problems including shortness of breath, headaches, fatigue, nausea, dizziness and eye, nose, lung and throat irritation. Some VOC's are suspected to cause cancer in humans and have been shown to cause cancer in animals. The long-term health effects caused by VOC's would depend on the concentration and length of exposure.


Some chemicals adhere better to different types of carbon materials and carbon blends. Over the years we’ve sourced and developed over 40 carbon blends. If you have an odor or chemical you need to remove, we have a blend to target it
