"Odor Kontroller"® Activated Carbon & Zeo-Sorb Gas Phase
Filters "Purafilter" Potassium Permanganate Impregnated
These series of filters offer cost effective solutions to poor indoor air quality which is
associated with over 40% of today's buildings. They will replace existing HVAC filters
and require no equipment retrofit. They save in freight since they are lighter than bulk
compound filters. Costly energy is saved because pressure drops are extremely lower
than bulk filters. They serve a dual function by removing both gaseous compounds and
particulate matter from the filtered air. The gaseous control compounds are
impregnated onto a polyester filter substrate and offer highly effective removal of
gaseous contaminants as well as solid airborne contaminants. Filters are offered in the
following medias: activated carbon, zeolite, potassium permanganate. Available as the
ultimate gas phase filter, these filters contain a blend of both activated carbon and
potassium permanganate. Filters are offered in thicknesses of 1" to 12" and are offered
in many face sizes.
Activated carbon filters are Bio-Kontrol* filters and potassium permanganate filters have
an inherent resistance to biologicalians. Zeo-Sorb ODOR KONTROLLER provides a
cost effective solution for removing unpleasant fumes and odors associated with
ammonia and ammonium compounds (e.g. Urine).

Change-A-Pleat™ Extended Surface Replaceable
Pleated Elements
Incorporates the features of MAXI-PLEAT filter series and more!
CHANGE-A-PLEAT system design can be used in pad holding
frames. Pleats save labor time and storage space, because they are
compressed to take up little space and are easy to transport. Units
are available with protective end caps and compression tied, or bulk
packed without end caps and no ties. CHANGE-A-PLEAT media is
available in pre-cut sizes or bulk rolls in 1", 2" & 4" thicknesses. A
Bio-Kontrol* filter.

Airo-Flo™ Extended Surface ASHRAE Cell Filters
Compact design with rigid construction that fits all HVAC systems.
This type filter is well suited for variable air volume systems where
there is changing air velocity, in units where there is turbulent air, high
temperature or high humidity. Available in 60-65%, 80-85% and
90-95% efficiencies. Their 6" and 12" depths enable them to be
installed where space is limited. Available with side access headers
and frame constructions of partical board or metal cell. No header,
metal cell shown left.

Kontrol-Flo™ Extended Surface Filter
KONTROL-FLO is ideal for variable air volume systems, because its
performance is not affected by changing air velocity or system shut
down. It is also ideal for equipment where space is a problem. This
rigid cell filter is encased in metal framing in 6" and 12" depths.
Peripheral headers are available for side access units.
KONTROL-FLO EF filters are available as Earth Friendlier products.
They use no metal except expanded metal for media support. Both
units are available as a Bio-Kontrol* filter.

Micro-Kontrol® H.E.P.A.
Used where the highest degree of filtration is desired. H.E.P.A. filters
are available in DOP efficiencies of 95%, 99.97% and scanned units
of 99.999%. As in the Airo-Flo, H.E.P.A. filters offer different framing
constructions and CFM capacities to suit your specific use. Wood
H.E.P.A. shown left. Metal cells available.
