Activated carbon has been specially treated to open up millions of tiny pores and fissures. This creates a huge internal surface area. In fact, less than a handful of carbon has the surface area of an entire football field. When polluted air is drawn into the air purifier, chemicals, gases and odors are trapped in these openings. An air purifier made specifically for chemicals and odors will have a thick filter of granular activated carbon. Avoid any air purifier that uses only a thin carbon filter. This type of air purifier simply does not have enough carbon to be effective. It will quickly become saturated and may stop adsorbing within weeks or even days. A large carbon filter could last up to two years depending on the level of odors and chemicals in the dwelling.
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
