The Allergy Machine is ideal for use in environments where there’s higher than normal humidity levels, such as a damp basement.  It features an activated carbon cloth, called a HEGA (high efficiency gas arrestor) instead of granular carbon. This specialized material was developed for the British military for use in their chemical gas masks.The HEGA carbon cloth is more efficient and less likely to become saturated in a damp setting compared to regular granulated carbon.

As in all Austin Air purifiers, there is the true medical grade HEPA filter, certified to remove 99.97% of airborne particles 0.3 microns in size, and 95% of particles 0.1 microns in size. Comes with wheels for easy portability.
