General
The Model C Disposable Carbon air filter is an
easy-to-install partial-bypass carbon type air purifi-
er for light duty IAQ applications in home and com-
mercial recirculated air systems. The filter uses
premium grade granular virgin coconut shell carbon
to remove odors by the adsorption process rather
than masking them with air fresheners. Odors are
controlled by surface adsorption on the carbon,
which has over one million square feet of surface
area per square foot of filter face area. Typical
household applications are the removal of odors
from bathrooms, cooking, smoking and entertain-
ing. Commercial applications may include restau-
rants, schools, medical offices, beauty salons,
health clubs, and offices.
Construction
A laminated cellulose honeycomb material forms
the base structure of the filter. The honeycomb pro-
vides for the exposure of a great amount of surface
area for full utilization of the carbon. Each individual
honeycomb cell is filled with granular activated car-
bon to either the 50% or 75% level. The 75% fill fil-
ter has a longer life than the 50% fill filter, but its air-
way pressure drop is greater.
The carbon is retained within the honeycomb cells
by a non-woven nylon mesh on both sides of the fil-
ter. The honeycomb is given additional strength by
a moisture-resistant die-cut beverage board frame
(standard sizes) or U-channel beverage board
(special sizes). Each order is individually sealed in
plastic to retain the carbon efficiency prior to instal-
lation.
Service Life
It is difficult to predict the life of any carbon filter. It
is a function of the concentration level of dust and
gaseous contamination for each specific applica-
tion. Even though sensitivity varies with the individ-
ual, the human nose is still the best indicator of the
need to change a carbon filter.
