rated to .3 or .1 microns. Extended surface filters are commonly known as HEPA (High Efficiency
Particulate Air) filters. First used commercially in 1961, these filters are honeycombed with fine
sheets of microporous material that can screen out particulates down to less than one third of a
micron size with a rated 99.99% efficiency. All spores of plants, fungi and most bacteria are thereby
trapped within the folds of the filter.
The collection media in this type of filter can be composed of various materials including hair,
spun glass, wool, paper and asbestos. (In the past, asbestos has been used in the manufacturing of
all types of filters. Since asbestos is cancer causing, be sure to specify a non-asbestos fiber). The extended surface media filter consists of folds of material woven back and forth. Corrogated aluminum
or paper separators are inserted perpendicularly to the filter face and separate the folds to help direct
airflow in an even, parallel fashion.
The airstream hits the filter material at a perpendicular angle and is forced to pass through the
many weaves of the filter before exiting. From the force of impact, inertia and the size of the media
web, particles are trapped within the filter. The result is that a very high efficiency is achieved, particularly with small diameter particles.
Extended surface filters have much higher resistance than electrostatic filters but they have a far
