"ULTRA" C dual filtration effect. "ULTRA" C MICRO-CK'R(TM) has an
activated carbon pad which acts as a molecular magnet attracting
and holding odor and contaminants. Available in 1" and 2" frames.
The activated carbon pad will become completely adsorbed by the
odors. The carbon pad is replaceable approximately every 6-9 months
depending upon the concentration of odors. Before washing, depress
the aluminum frame and remove carbon pad. EZ to clean, spray each
side with a degreaser and rinse. Constructed with the same high
quality as the "ULTRA" 1" and 2" with an added plus. All filters
come with 2 extra carbon pads. UL Class 2 Flammability only.
