Activated carbon / activated charcoal is widely recognized as the safest, most effective way to treat odors and chemicals, while HEPA (High Efficiency Particle Air) filters are the gold standard for removing particles. Together they provide the most complete and versatile air cleaning system available. Both tried and proven filtration medias.
Carbon that is 'activated' undergoes a process that opens up millions of tiny pores and fissures to enhance the material's adsorbent properties. The process creates a very large internal surface area, which is key to the power of activated carbon - the more surface area - the more the carbon can adsorb. Only one pound of activated carbon typically has a surface area of 125 acres. Activated carbon is so effective that it's used in military gas masks. | multi-stage filtration process |
HEPA stands for high efficiency particulate air filter and describes a filter that can remove at least 99.97% of airborne particles 0.3 microns in diameter. Particles of this size are used to evaluate the performance of a filter because they are among the most difficult to remove. However, particles that are larger or smaller than 0.3 microns can be filtered with even greater efficiency due to the nature of the filter’s design. True HEPA filters are composed of a dense web of fibers designed to trap particles. This type of filter was first used in the 1940’s to trap radioactive contaminants in the air and protect scientists who were developing the first nuclear weapons. Today, HEPA is considered the safest and most efficient method to treat airborne particles.
