* MERV, Minimum Efficiency Reporting Value,
is a number from 1 to 16 that is relative to an 
air filter’s efficiency
, according to a universal
filtration standard. The higher the MERV, the
more efficient the air filter is at removing
particles.

+ Energy Cost Index, or “ECI,” is a filter rating
system that looks at the filter’s efficiency over
its lifetime and the energy required to move air
through that filter. ECI compares filters of similar
construction, under the same conditions of
operation and provides an indicator of true
performance. Specifically, the formula is dollars
per percent of filter efficiency. The lower the
value, the better the filter. A filter with an ECI
of five stars maintains its efficiency over its
life and uses less energy to move air through
the filter. It is in the top 20% of all filters
evaluated. A four star filter has a lower
ECI value, and the pattern continues down
to one star, the poorest performers. 

MERV 8 Filter Removes Bacteria,
Airborne Particulate; Provides Exceptional
Value for FDA Facilities with
High Sanitation Standards

Background:

Food Safety is the #1 concern among the 395 respondents to a recent annual survey of food processors.   
Food-borne illness is back in the news – just as new rules on reporting contamination, contained in the
FDAAA (FDA Amendments Act) of 2007 have gone into effect. 

For food and beverage facilities, airborne contaminating bacteria is a chief concern. A new air filter
technology now addresses airborne bacteria very effectively.  This new technology also produces
immediate, substantial reductions in the energy used by a plant’s HVAC system. (In a typical food
processing plant, HVAC is 60% of utility costs.)

Camfil Farr, a world leader in filtration products for food and beverage processors, pharmaceutical
manufacturers and other FDA facilities, has introduced the first true MERV 8*(ASHRAE 52.2-2007)
30/30” air filter.

The 30/30® is a pleated panel filter engineered to remove bacteria and airborne particulate. 
It was designed to deliver the greatest overall value in facilities with high sanitation standards and
high rates of air changeover.  The 30/30 is ideal as the first phase of filtration in large AHUs,
and is an excellent pre-filter for laboratories, quality inspection and other areas where HEPAs or
other higher efficiency filters are required.  It provides a significant performance upgrade from
traditional MERV 8 filters. 

The 30/30 MERV 8 has very low initial resistance, and low maintained resistance, to airflow,
and the lowest average pressure drop of any MERV 8 filter.  This translates immediately into
energy savings that are measurable, and significant.

The MERV 8 30/30 filter is distinctive in having earned five stars on the ECI (Energy Cost Index+) -
the best-possible performance ranking.  The Camfil Farr MERV 8 30/30 has a distinctive design
that provides full use of the media for significantly greater capacity than conventional MERV 8 filters. 
This means a longer service life, and less-frequent change-outs.  

The 30/30 has proved highly effective as a system’s final filter for a broad range of recirculation
applications, including bulk powder dispensing rooms, many manufacturing areas, animal labs,
and packaging areas.  It is an exceptional pre-filter for sterile manufacturing and other areas that
use HEPA or ULPA filters.    

The media for the 30/30 filter is all-mechanical, rather than electrostatic, and maintains consistent,
high removal efficiency throughout the filter’s life.  In contrast, other MERV 8s are made with
electrostatically charged media, whose efficiency plummets as dust loads.  (Buyers of electrostatic
media filters are advised to obtain the “discharged MERV” rating, in order to determine the actual,
in-service performance level of the product, to make valid comparisons.)

The Camfil Farr Performance Guarantee Program guarantees that the 30/30 will maintain its
efficiency over time, and will last longer than any pleated panel filter.  The radial media pleats on
the 30/30 are secured by a welded wire grid, spot-welded on one-inch centers.  The grid is treated
for extended corrosion protection and is bonded to the media to prevent oscillation. 

The 30/30 also has very high structural integrity. A high wet strength beverage board frame
creates a stable, non-yielding media pack. The media pack is bonded to the frame, and diagonal
support members are bonded to each pleat to enhance rigidity through bridge-style engineering. 
Filter bypass is virtually eliminated. The MERV 8 30/30 is guaranteed to 2.0” w.g. without
media pack failure.  It is well-suited to the higher filter face velocities common in food processing.

The MERV 8 30/30 is a UL Class 2 or 1 filter, and is available in 2” and 4” configurations. 
Its unique combination of performance, energy savings and applications flexibility makes it an
excellent tool for protecting product, and product packaging materials, from contamination by
sources inside and near the facility, (including workers and air-blowing equipment) and from
airborne bioaerosols that can accelerate spoilage or otherwise compromise product shelf life.
The 30/30 also enhances the health and productivity of workers, by capturing a vast range of
mold-carrying particles and allergens.

The Camfil Farr 30/30 may be used to meet requirements of the U.S. Green Building Council
(“LEED”) in terms of efficiency, energy savings and reduced disposal impact.
