Both airborne chemicals and particles aggravate, and in some cases, may even trigger allergies and asthma. It is therefore vital that an air cleaner for respiratory conditions provides both a deep-bed activated carbon filter and a medical grade HEPA filter.

About Our Activated Carbon + HEPA Filtration System

About "Activated" Carbon

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 1 25 acres. Activated carbon is so effective that it's used in military gas masks.

About HEPA Filters

HEPA stands for high efficiency particulate air 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. Today, HEPA is considered the safest and most efficient method to treat airborne particles.

AllerAir allergy and asthma air purifiers provide, not only HEPA protection (cleaning in exess of 99.97% of particles as small or smaller than 0.3 microns), they also contain the largest amount of activated carbon in the industry.
